Facts, not fads.

Quick glossary

These are the terms behind the calculator. Know what they mean and the numbers stop feeling arbitrary.

Energy balance — the only law that matters

Your body obeys one equation: calories in versus calories out. Eat more than you burn and you gain weight. Eat less and you lose it. There are no magic foods and no evil ones — there are only amounts. Everything else in nutrition is optimization around this law.

Your total daily energy expenditure (TDEE) is not one thing; it is the sum of the four components below. That matters because training is only part of what you burn, and ordinary movement can change substantially when you diet.

Find your maintenance

Two ways. Best: track everything you eat and weigh yourself daily for two weeks — if weight is stable, that's maintenance. Two weeks matters because water, stored carbohydrate, sodium, and food in your gut can hide the true trend for several days.

Faster: estimate it. Bodyweight in pounds × 14–16 gives a decent starting point for active people. Treat every estimate as a starting guess, not gospel, because activity and individual energy needs vary more than any equation can capture.

Set your target

• Fat loss: 15–20% below maintenance (roughly 300–500 calories). This is enough to move the scale while keeping hunger, training, and muscle retention manageable.
• Muscle gain: 5–15% above maintenance (roughly 200–300 calories). Muscle can only be built so fast; calories beyond that ceiling mostly add body fat and create a longer cut later.
• Recomposition: eat at maintenance. Stored body fat can help cover the energy cost while protein and progressive training support muscle gain, but progress is slower.

Small, boring adjustments beat dramatic ones because they are easier to sustain and make it clear which change actually worked.

Protein — the priority macro

Eat 0.7–1.0 gram per pound of bodyweight per day. Cutting? Aim for the top end because food is scarce, hunger matters more, and muscle is at greater risk; protein helps with both fullness and muscle retention. Bulking? The middle is fine because calories are plentiful and the extra protein is unlikely to build extra muscle.

Note: Stoic Cookie's preference is at least 1.0 g of protein per pound of bodyweight per day — the calculators use this as a floor.

Protein repairs muscle and costs roughly 20–30% of its own calories just to digest, which is another reason it earns priority.

Eat: lean meats, fish, eggs, Greek yogurt, and whey. Spread protein across 3–5 meals because repeated servings make the daily target easier to hit and give muscle-building machinery several chances to respond.

Fat — don't fear it

Eat 0.3–0.5 gram per pound of bodyweight. That range leaves enough dietary fat to support normal physiology and make meals satisfying without crowding out the carbohydrates that fuel hard training. Drop it too low and mood, libido, and training can suffer. Nuts, olive oil, eggs, and fatty fish are practical sources.

Carbs — fuel, not the enemy

Carbohydrates fill whatever calories remain after protein and fat. Those two have clearer minimum targets; carbohydrates are the flexible lever and directly support hard training by replenishing muscle glycogen, the stored carbohydrate used during lifting.

My method: lock protein and fat, then move carbohydrates up or down to create your surplus or deficit. My body runs great on them — yours might differ. Adjust to appetite, digestion, and training performance.

Adjusting — the two-week rule

Weigh yourself daily, then compare weekly averages — never one day against another. Daily weight swings reflect water, stored carbohydrate, sodium, and food in your gut; two full weeks of averages are long enough to reveal whether the underlying trend has actually stalled.

If nothing moves for two full weeks, change one variable: drop 100–150 calories, or add one cardio session. Never both at once, because changing two levers hides which one worked and can create more restriction than you need.

Keep calories as high as you can while still progressing. Less restriction means less diet fatigue, better training, and more room to reduce food later if a real stall appears.

If you hate tracking

You don't have to count forever. These habits work because they make filling, protein-rich food the default and quietly reduce calorie density:

• A protein source at every meal — easier protein coverage and better fullness.
• Water before meals — thirst is removed from the hunger equation.
• Eat slowly — your fullness signals have time to catch up.
• Skip liquid calories most of the time — they add energy with little fullness.
• Make half your plate vegetables — more food volume for fewer calories.
• Keep highly processed food as the exception — it is usually easier to overeat.

Eat to grow

Run a small surplus: 5–15% above maintenance. Muscle growth is rate-limited by training status and recovery; once enough energy is available, a bigger surplus does not force faster muscle growth. It mostly adds body fat and buys you a longer cut later.

Aim for the scale to climb 0.25–0.5% of your bodyweight per week — for a 180-pound lifter, that is roughly half a pound to a pound a week. Faster than that is a sign the surplus is doing more for fat gain than muscle gain.

Train with intent

Progressive overload is king: over time, do more — more weight, more reps, or more productive sets. That rising demand tells your body its current capacity is not enough; repeating the same work removes a major reason to adapt.

• Volume: roughly 10–20 hard sets per muscle per week is a productive range. Start at the low end and add only when recovery and performance support it, because more work is useful only if you can adapt to it.
• Frequency: hitting each muscle twice a week is a practical way to distribute that work. You get more high-quality sets instead of cramming everything into one exhausted session.
• Repetitions: anything from roughly 5 to 30 can build muscle if the set goes near failure. The 6–12 range is a practical default because it balances load, joint stress, and time.
• Rest: 2–5 minutes on heavy compound lifts and 1–2 minutes on accessory work. Rest enough to perform your next set well; rushing lowers the load or repetitions you can produce without creating extra growth.

Form beats weight. Controlled technique keeps tension on the intended muscle and limits compensatory movement; adding load only counts as progress if the target muscle is still doing the work.

Realistic rates

Beginners: up to ~1–1.5% of bodyweight per month. Intermediates: half that. Advanced: glacial. This is a years-long project. Anyone promising faster is selling something.

Body recomposition — building while leaning out

Body recomposition works best if you are a beginner, returning after time off, or carrying extra fat. Eat at maintenance, keep protein high, and train progressively: stored body fat can cover some energy needs while a novel training stimulus makes muscle gain more likely.

Expect slow. If you are already lean and experienced, pick a direction — gain or cut — because your margin for doing both at once is much smaller.

The deficit is the diet

Start around 15–20% below maintenance. That is usually large enough to produce a clear trend but moderate enough to preserve training quality, lean tissue, and adherence.

Target 0.5–1% of bodyweight per week. For a 200-pound person, that is 1–2 pounds a week. Leaner and more advanced people should favor the slower end because they have less stored energy and more muscle to protect.

Protect the muscle

Keep protein at the top end: 0.8–1.0 gram per pound of bodyweight. In a calorie deficit, food is scarcer, hunger matters more, and muscle is more vulnerable; higher protein improves fullness and gives your body the raw material to retain lean tissue.

Keep lifting hard — the tension that built the muscle is the signal to keep it. Do not slash calories to the floor. Keeping intake as high as possible preserves training, limits diet fatigue, and leaves room for a small reduction when a genuine stall arrives.

Cardio is a tool

Cardio burns calories — that is its job in a cut. Start with one short session a week (15 minutes at a comfortable pace), then add a day, time, or intensity only after the two-week weight trend truly stalls. Starting low controls fatigue and preserves the smallest effective dose for later.

Daily steps — part of non-exercise activity thermogenesis (NEAT) — matter enormously. A daily walk target is easier to recover from and more consistent than heroic weekend cardio, and it helps replace the movement that often drops unconsciously during a diet.

Stalls and diet breaks

First, confirm the stall: if two weekly weight averages show no movement, change one variable. The wait filters out water, stored carbohydrate, sodium, and gut-content noise; changing only one lever shows whether that change actually worked.

Then use breaks deliberately: after roughly 8–12 weeks of dieting, spend 1–2 weeks eating at maintenance before resuming the cut. A diet break is controlled maintenance, not an untracked free-for-all.

Why it helps psychologically: diet fatigue is real. More food and fewer restrictions can reduce the sense of grind, restore adherence, and make the next block easier to execute.

Why it may help physiologically: maintenance intake can partially reverse some short-term adaptations to dieting, including suppressed leptin, a hormone involved in energy balance and hunger. Hunger can ease and training performance often rebounds. This is a partial reset, not a metabolic hack.

Practical rule: take 1–2 weeks at your current maintenance calories every 8–12 weeks of sustained dieting, hold normal protein and training, then resume the deficit.

Sleep — the silent lever

Aim for 7–9 hours because sleep changes both sides of the diet. Short sleep tends to raise ghrelin, a hormone that increases hunger, and lower leptin, a hormone involved in fullness and energy balance. It can also reduce training quality and spontaneous movement.

Poor sleep does not just make dieting feel harder — it can shift weight loss away from fat and toward lean tissue. Sleep is a body-composition tool.

“Metabolic damage,” honestly

Your metabolism adapts downward when you diet — that is real. But much of the slowdown is explained by physics and behavior: a smaller body burns less, and tired dieters often move less without noticing. “Permanent damage” is not a useful model.

Returning to maintenance raises food intake, supports normal movement and training, and allows the adaptive component to recover over time. That is why a maintenance phase belongs after a long cut instead of immediately launching another aggressive deficit.

Measure right

Use weekly average weight, photos under consistent conditions, and a waist measurement. No single measure tells the whole story: scale weight includes water and food, while photos and waist changes can reveal fat loss that a stable scale hides.

During body recomposition, bodyweight can move slowly even while body composition changes. Judge trends over weeks, not days, because the signal is smaller than normal daily noise.

Quick glossary

The language can make a complicated subject sound simpler than it is. These terms describe categories and biological systems — not endorsements.

What a “cycle” actually means

Cycle, blast, cruise, TRT — these are patterns of use, not recommendations. A cycle means a defined period of use followed by time off. A blast is a higher-exposure period; a cruise is a lower baseline period. TRT is doctor-prescribed replacement for low testosterone — a medical treatment, not a cycle.

People argue endlessly about which pattern is “best.” The honest answer: they carry different tradeoffs, and every pattern suppresses natural production while external androgens are present.

Why cycles exist as a concept

The central tradeoff of all AAS use is HPTA suppression — your brain stops telling your testes to produce testosterone while external androgens are present. The “cycle” concept is an attempt to manage that tradeoff: defined periods of use, then time off to recover.

Whether that works well in practice is debated. Recovery varies between people, can take longer than expected, and is never guaranteed.

The building blocks

People talk about compounds in roles, not just names. Understanding the role a compound plays matters more than memorizing a list.

• Testosterone as the base concept: the reference androgen everything else is compared with.
• DHT-derivatives: compounds such as masteron and primobolan are non-aromatizing and carry a different cosmetic and androgenic character.
• 19-nors: compounds such as nandrolone and trenbolone are potent and bring their own baggage, including sexual-function and prolactin-related discussions.
• Orals versus injectables: categories with different routes, convenience, metabolism, and patterns of liver burden.

These are classification tools, not instructions or a menu.

The support concepts

Aromatization: testosterone can convert to estrogen. Managing that balance is a whole category of discussion, not a dosage chart. Estrogen is not simply a side effect; it has roles in bone, sexual function, mood, and cardiovascular biology.

Prolactin: this pituitary hormone becomes especially relevant in conversations about 19-nor compounds, but symptoms alone do not identify a prolactin problem.

Cardiovascular: AAS can affect cholesterol, blood pressure, heart structure, and hematocrit — the proportion of blood made up of red cells, which can affect viscosity. This is the serious long-term ledger.

Liver and kidney stress: liver burden is especially associated with many oral compounds, while kidney risk may be direct or indirect through blood pressure, body mass, and other strain. Exposure and duration shape the risk.

These are the categories knowledgeable users monitor. Knowing they exist is the education.

Bloodwork: what people monitor and why

The concept is baseline before, check during, and check after. Bloodwork replaces guessing with data, but interpretation still needs medical context.

Time on, time off

The principle: time off should respect time on. Coming off means facing suppressed natural production. Recovery concepts people discuss include SERMs — drugs that alter estrogen-receptor signaling and can stimulate the HPTA signal. That is a mechanism category, not a protocol.

Indefinite blasting without breaks is where the long-term bills — cardiovascular risk, fertility impairment, and dependence on external hormones — pile up fastest.

The honest price list

Every compound has a price, and exposure and duration scale it. The ledger can include cardiovascular strain, lipid damage, HPTA suppression and possible infertility, hair loss and acne shaped by genetics, and psychological effects.

Anyone who tells you a cycle is a free lunch is selling something.

Cycle design theory

This is a framework for understanding how experienced people organize the problem. It is not a list of instructions, an example cycle, or a substitute for a doctor.

The family tree

Every anabolic steroid is derived from testosterone, in three branches: testosterone itself, which aromatizes to estrogen; DHT derivatives such as masteron and primobolan, which do not aromatize and have strong androgen-receptor binding; and 19-nors such as nandrolone and trenbolone, which are often described as less androgenic, generally aromatize less, and carry progestogenic activity.

Why it matters: the branch helps predict the side-effect family you may be managing. It does not predict an individual's exact response.

Build by role, not by name

Experienced users think in roles: a testosterone-base concept, a primary anabolic role, and support roles around estrogen balance or separate growth pathways.

Why: role-based thinking keeps the design goal-driven. A stack of random compounds is how overlapping side effects multiply.

Phase thinking

Bulk, cut, cruise or health phase, and rebound are concepts describing what a phase is for: gaining phases; fat-loss phases that preserve muscle; health phases where everything non-essential is dropped so markers can recover; and the post-cut rebound window when sensitivity may be higher.

Why: different goals need different structures. Running one structure forever is how health markers never get room to recover.

Recognizing estrogen: high versus low

This is recognition, not treatment. Signs associated with high estrogen can include bloating and water retention, blood pressure creeping up, chest or gyno sensitivity, moodiness or anxiety, acne flare-ups, and erection or libido trouble. Signs associated with low estrogen — often after overdoing control — can include achy or dry joints, fatigue, low libido, mood swings, and mental fog.

Why: crashed estrogen can feel as bad as high estrogen. The target is balance, and knowing which side you may be on is the entire education. What to do about it is a doctor conversation; symptoms alone do not confirm a lab value.

Side effects have causes

Water retention can reflect estrogen, renin–angiotensin–aldosterone system stimulation, or growth hormone. Blood pressure can reflect water retention, stimulants, or an elevated red-cell count. Suppressed HDL cholesterol can reflect oral compounds or overly low estrogen. Insomnia and reflux are often discussed with trenbolone or stimulant overuse.

Why: when you understand the cause-category, you stop guessing — and learn that most side effects are the price of a specific choice, not bad luck. A symptom can have many causes, so this framework organizes questions; it does not diagnose them.

The design philosophy

Start with the lowest effective approach and let data drive changes: escalate only when progress has truly plateaued in the gym, and pull back when bloodwork or health markers skew. Think in multiple pathways — androgens are one lever; growth hormone and insulin sensitivity are separate ones. Pick tools for the individual's actual response, not forum consensus. Save the harshest compounds for last, if ever.

And the big one: stalled progress usually is not solved by more. Audit sleep, food, training, and stress before touching anything else.

Why: every addition has a price. The cheapest gains are the ones you get from fixing the basics.

Field notes · n=1

My experience has included testosterone-based cycles and DHT-derived compounds. The useful version of that story is not a list — it is what changed, what the bloodwork showed, what I misread, and which conclusions survived hindsight.

This is what happened to me. It is not a template. Personal experience is evidence about one person. It cannot establish what will happen to someone else, and it does not turn correlation into causation.

The bottom line

Volume landmarks — how much is enough

MEV means minimum effective volume — the least work that grows muscle. MAV means maximum adaptive volume — the productive sweet spot. MRV means maximum recoverable volume — the most work you can recover from. Below MEV, you are maintaining; above MRV, you are digging a recovery hole.

Start at the low end of these weekly hard-set ranges. These ranges count direct sets — the lower targets (front delts, rear delts, glutes) assume meaningful indirect work from compound pressing, pulling, and hip-hinge movements. Add a set per muscle each week. When performance stalls, soreness lingers, or joints ache, you have found your current ceiling.

Why: junk volume past your MRV does not grow more muscle. It creates fatigue that can mask the growth already happening.

The mesocycle — train in blocks

A mesocycle is a training block built around one progression arc: usually 4–6 weeks of accumulating work, then a deload. One proven template starts with weeks 1–2 at baseline effort — about 2 reps in reserve, adding one set per muscle each week. Weeks 3–4 push to about 1 rep in reserve while holding volume. Week 5 overreaches at 0–1 reps in reserve, with an extra set only for priority muscles. Week 6 deloads with half the sets, about 3 reps in reserve, and light pump work.

Why: fatigue accumulates and hides your fitness. The deload drains fatigue while the fitness you built stays, so the next block starts from higher ground.

Effort — RIR, plainly

RIR means reps in reserve: how many more good repetitions you could have completed. Most work sets land around 1–2 RIR. The last isolation set can reach 0 RIR — near failure. A useful effort target is roughly 7.5 RPE, or rating of perceived exertion, which works out to about 2–3 RIR, with work sets taken close to failure.

Why: proximity to failure is the stimulus. Stopping five repetitions short is cardio with weights.

Rep ranges by exercise type

• Compound lifts — squats, presses, rows, and deadlifts: 3–8 repetitions.
• Machines and cables: 8–15 repetitions.
• Isolation work — curls, lateral raises, and calves: 10–20 repetitions.

Why: heavy compounds in lower ranges build strength without drowning you in fatigue; isolation in higher ranges lets you chase the local stimulus while sparing joints. Muscle can grow across all of these ranges near failure — match the range to the exercise.

Exercise selection — the filter

Most lifters do not need a new program. They need better exercise selection. Run every movement through this filter:

• Does it load the target muscle through a full range of motion?
• What is its stimulus-to-fatigue ratio — the local muscle stimulus versus the systemic and joint cost?
• Does it fit your structure, mobility, and injury history?
• Is it redundant with another movement already in the program?

Three row variations doing the same thing are one good row done three times.

Why: the best exercise stimulates the target with the least unnecessary cost, leaving recovery capacity for growth.

Frequency

Training each muscle twice a week is the default — a practical distribution, not a growth lever. Research finds no meaningful hypertrophy difference between frequencies when weekly volume is matched; the benefit of splitting is keeping more sets high quality instead of cramming all the work into one exhausted session. Then individualize: fast-recovering muscles can go more often; beat-up joints get less.

Why: spreading volume across the week keeps more sets high quality instead of cramming all the work into one exhausted session.

Progression — the logbook, done right

Track 4–6 week trends, not session-to-session jumps. Add repetitions first, then load, then sets. Execution quality is progression too — the same weight with better control can create more stimulus in the target muscle.

The alternative is the logbook trap: chasing strength numbers that do not build the intended muscle. Chase the muscle, not the number.

Deloads — read the signals

Plan a deload every 4–6 weeks, or take one earlier when motivation dips, joints ache, sleep or digestion go sideways, or performance drops. Performance is often the last thing to fall. Sleep, mood, and appetite wave red flags first.

A deload is not quitting. It is what makes the next block grow.

Specialization and the long game

Lagging body part? Run a specialization block: give the priority muscle extra volume and frequency while everything else sits at maintenance volume. That concentrates a finite recovery budget instead of pretending every muscle can be the priority at once.

An offseason can push bodyweight upward at 0.25–0.5% per week across 18–24 week blocks, followed by time to consolidate the gain.

Why: muscle is built in long, boring pushes — not 4-week programs.
