The Complete Prohormone
Dosing Guide
Prohormone dosing isn't complicated — but getting it wrong is one of the fastest ways to waste a cycle. Whether you're planning your first run or dialing in an advanced protocol, the difference between results and frustration comes down to three things: dose, timing, and cycle length.†
This guide covers everything. Beginner to advanced prohormone dosing, on-cycle timing, cycle length by experience level, common mistakes that kill results, and how to time your PCT. Everything you need to run a clean, effective cycle at Pre Nutrition in Richmond, VA.†
Why Dosing Discipline Drives Results
Most people who underperform on a prohormone cycle didn't pick the wrong compound — they ran the wrong dose. More is not always better. Prohormones work within a dose-response range: below it, you get minimal results. Above it, you increase side effect risk without additional benefit. Hit the window and you get everything the compound offers.†
Discipline also means consistency across the cycle. Skipping doses, cycling on weekends only, or doubling up after a missed day all undermine the steady hormonal environment that prohormone gains require. These compounds work best when blood levels stay stable — which means taking them at the same time each day, every day.†
The good news: once you understand how to structure a cycle — what dose to start with, how long to run it, when to stop — everything else follows naturally. The framework below applies to every prohormone in the Pre Nutrition catalog, beginner to advanced.
Beginner Dosing Protocols
If this is your first prohormone cycle, one thing matters above everything else: don't complicate it. Beginners respond well to single-compound cycles at the manufacturer's recommended dose. There's no need to stack, no need to run extended cycles, and no need to push dose above what's on the label.
The right beginner compounds are non-methylated, mild on the liver, and forgiving on the endocrine system. The TESTOSTERONE SUPPORT BEG stack — built around ANDRIOL and BULASTERONE — is the ideal starting point. Both are 4-Andro and DHT-derived respectively, both non-methylated, and both forgiving enough to run solo before stacking.†
Beginner cycle parameters:
| Parameter | Recommendation | Notes |
|---|---|---|
| Compounds | 1 (single compound) | Stack only after your first successful solo cycle |
| Cycle Length | 4–6 weeks | Shorter first cycle = better data on your personal response |
| Dose | Label dose | Never exceed label dose on a first cycle |
| Timing | Same time daily | Morning with food is the default for most compounds |
| On-Cycle Support | Optional (Liver-Rx if methylated) | Non-methylated compounds don't require liver support† |
| PCT | 4 weeks Novedex XT | Start PCT the day after your last dose |
After your first cycle, note everything: strength changes by week, energy levels, sleep quality, recovery speed. This data is your roadmap for the next cycle. Beginners who track their first cycle intelligently almost always progress more efficiently than those who jump straight to stacking.
Intermediate Dosing Protocols
Intermediate status means you've run at least one successful prohormone cycle, completed PCT, and had a clean off-cycle period. You know how your body responds to hormonal compounds. Now you can start stacking and targeting specific outcomes more precisely.†
At the intermediate level, the most productive move is adding a second compound that complements the first — not just adding more of the same. A testosterone base like ANDRIOL pairs with a more targeted compound like OSTA-PLEX or DECABOLIN for a synergistic effect — more muscle signaling, better recovery, and a clearer body composition result than either compound alone.†
| Parameter | Recommendation | Notes |
|---|---|---|
| Compounds | 2 (base + targeted) | Testosterone base + goal-specific second compound |
| Cycle Length | 6–8 weeks | Extended run allows full expression of slower compounds like Decabolin† |
| Dose | Label dose on both | Stacking amplifies effect — don't exceed label on stacked cycles |
| Timing | Same time daily, split if directed | Some compounds are better split AM/PM — follow label |
| On-Cycle Support | Liver-Rx if any methylated compound | Run Liver-Rx from day 1 through last dose of cycle† |
| PCT | 4 weeks Arimiplex | Stronger PCT recommended for stacked cycles |
The intermediate stacks at Pre Nutrition — Mass & Strength Int, Cut & Definition Int, Recomp Int, and Test Support Int — are all built on this two-compound framework. Each is curated for goal alignment and compound synergy so you don't have to guess the pairing.†
Advanced Dosing Protocols
Advanced cycles are for athletes with multiple completed prohormone cycles, solid PCT experience, and a strong understanding of how their body responds to these compounds. Advanced does not mean more — it means more targeted. The distinction between an intermediate and advanced cycle is compound selection and synergy, not dose escalation.†
Advanced stacks incorporate three or more compounds, often including more androgenic options like HALODROL, TRENABOL, or DYMETHAZINE. On-cycle liver support with LIVER-RX is mandatory — not optional — on advanced cycles. PCT with ARIMIPLEX is the standard.†
| Parameter | Recommendation | Notes |
|---|---|---|
| Compounds | 3–4 (curated stack) | Use pre-built Advanced stacks — combinations are synergy-tested |
| Cycle Length | 6–8 weeks (8 max) | Do not extend beyond 8 weeks regardless of experience |
| Dose | Label dose only | Advanced compounds are potent — label dose is effective dose† |
| Timing | Per individual compound labels | Multi-compound stacks may have different timing requirements |
| On-Cycle Support | Liver-Rx mandatory | Start Liver-Rx day 1, run through final dose day† |
| PCT | 4 weeks Arimiplex (minimum) | Some advanced users run 6 weeks PCT after heavy cycles |
On-Cycle Timing: When to Take Your Dose
Timing your dose correctly keeps blood levels stable and maximizes the effectiveness of every compound. The general rule: take your prohormone at the same time every day. Consistency matters more than the specific time of day for most compounds. That said, some timing considerations apply:
| Scenario | Recommended Timing | Why |
|---|---|---|
| General / Default | Morning with first meal | Food increases absorption for most oral prohormones; morning dose aligns with natural testosterone peak† |
| Training Day | 60–90 min pre-workout | Some users prefer dosing before training sessions to time peak levels with the workout window† |
| Split Dosing (label directed) | AM + PM, with meals | Helps maintain steadier blood levels across the day for compounds with shorter half-lives† |
| Missed Dose | Skip — do not double up | Doubling spikes levels and increases side effect risk without benefit |
Always take prohormones with food. This is especially important for compounds with lipophilic (fat-soluble) delivery systems — the fat in a meal increases oral bioavailability and significantly improves how much of the active ingredient reaches systemic circulation.†
Cycle Length: How Long to Run Each Protocol
Cycle length is one of the most common points of confusion — and one of the most consequential decisions in any prohormone protocol. Longer is not always more effective. Every compound has a window where gains accumulate efficiently. Beyond that window, the risk-to-reward ratio shifts in the wrong direction.†
Beginner
Enough time to see genuine results from non-methylated compounds. Shorter cycles are easier to recover from and give you a clean baseline to evaluate your body's response before committing to longer protocols.†
Intermediate
The sweet spot for most stacked cycles. Longer runs allow slower compounds like Decabolin and Equipoise to fully express their gains — these compounds peak later in the cycle and benefit from extended time.†
Advanced
Even with experience and aggressive compounds, 8 weeks is the ceiling. Beyond this point, endocrine suppression deepens without proportional gain increases, and PCT recovery becomes significantly harder.†
The one exception to cycle length rules: highly androgenic compounds like Halotestin should be run no longer than 4 weeks, even for advanced athletes. Short, sharp cycles are appropriate for compounds with strong androgenic profiles.†

Off-Cycle Breaks: Why You Can't Skip the Reset
The off-cycle period is where long-term gains are protected. After completing PCT, your body needs time to fully restore natural hormone production before the next cycle begins. Skipping the off-cycle break and running back-to-back cycles is the single fastest way to cause lasting hormonal disruption.
The minimum off-cycle break after a completed PCT is equal time off as you spent on cycle plus PCT combined. If you ran 8 weeks on and 4 weeks PCT, take at least 12 weeks off before the next cycle. This is the "time on = time off" rule — it's the industry standard for a reason.
During the off-cycle period:
- Train consistently Maintaining your training intensity during the off-cycle preserves gains and keeps your baseline fitness high for the next run. Strength may decrease slightly — this is normal and expected.†
- Keep protein high Dietary protein remains the primary driver of muscle protein synthesis off-cycle. Keep protein at or above 1g per pound of bodyweight to support retention of cycle gains.†
- Monitor how you feel Energy, libido, mood, and sleep quality are all proxies for hormonal recovery. If any of these are still significantly off at the 4-week post-PCT mark, extend your off-cycle period before considering another run.
7 Common Dosing Mistakes That Kill Results
These mistakes show up consistently across beginner and intermediate cycles alike. Avoiding them doesn't require advanced knowledge — just discipline and a clear protocol before you start.
- Mistake #1 — Exceeding Label Dose "For Better Results" Prohormone dosing is optimized by the manufacturer. Exceeding it doesn't linearly increase results — it increases side effect risk and stresses the liver and endocrine system without proportional gain. Label dose is effective dose.†
- Mistake #2 — Skipping Doses, Then Doubling Up Inconsistent dosing creates hormonal instability. Doubling up after a miss spikes levels unpredictably. If you miss a dose, skip it and resume your next scheduled dose at the normal time.
- Mistake #3 — Running Cycles Too Long "More weeks = more gains" is the most expensive mistake in prohormone use. Beyond 8 weeks, endocrine suppression deepens significantly while marginal gain rate drops. Respect the cycle length ceiling.†
- Mistake #4 — Skipping PCT or Running Weak PCT PCT is not optional. Every prohormone cycle suppresses natural testosterone production to some degree. Without proper PCT, recovery is slow, gains are lost, and long-term hormonal health is at risk. Use ARIMIPLEX or NOVEDEX XT — don't improvise.†
- Mistake #5 — Stacking Too Many Compounds Too Soon Stacking multiple prohormones before understanding how a single compound affects you makes it impossible to isolate what's working and what's not. Run one compound successfully before stacking.
- Mistake #6 — Taking Prohormones on an Empty Stomach Most prohormone compounds have significantly better absorption when taken with food — particularly with a fat source. Taking on an empty stomach reduces bioavailability and can cause nausea.†
- Mistake #7 — Running Back-to-Back Cycles Without a Break Time on = time off. Running consecutive cycles without full hormonal recovery is the fastest path to lasting hormonal suppression. Always complete the full cycle → PCT → off-cycle sequence.
PCT Timing: When to Start and What to Use
Post Cycle Therapy begins the day after your last prohormone dose — no waiting period, no gap. The goal is to restart natural testosterone production as quickly as possible while the cycle compounds clear your system.†
Which PCT product to use depends on your cycle:
Light Cycles (Beginner)
- 4-week protocol
- Natural aromatase inhibitor
- Ideal for non-methylated single compounds†
- Lower suppression requires lighter PCT
Standard + Advanced Cycles
- 4–6 week protocol
- Pharmaceutical-grade formula
- Required for stacked and advanced cycles†
- Strongest PCT option in catalog
What to do during PCT: Continue training at normal intensity. Keep protein high. Sleep is non-negotiable — this is when your endocrine system is doing the most recovery work. Avoid alcohol and any other hormonal compounds during PCT.†
What success looks like: By week 3–4 of PCT, most users notice energy returning, libido normalizing, and mood stabilizing. If these markers are still significantly off at the end of PCT, extend the off-cycle period and consider consulting a healthcare professional before running another cycle.
