Post Cycle Therapy Canada
The Complete PCT Playbook
Your cycle is over. Now the real work starts. This guide covers everything Canadian athletes need to know about PCT — the drugs, the timing, the bloodwork, and the lifestyle — so you keep what you built.
Why PCT Is Non-Negotiable
Every steroid cycle suppresses your body’s natural testosterone production. Your hypothalamic-pituitary-gonadal (HPG) axis detects the exogenous androgens and shuts down LH and FSH. Your testes stop working. When the cycle ends, that suppression doesn’t lift automatically — your body sits in a dead zone where testosterone is low, estrogen is relatively elevated, and the feedback loop is slow to restart.
Post Cycle Therapy (PCT) is the structured protocol that bridges that gap. It uses pharmacological agents to kick-start the HPG axis, bring testosterone back to baseline, and prevent the muscle wasting, depression, fat gain, and libido crash that follow an unmanaged cycle end.
PCT is not optional. It’s not something you do if you feel bad after. It’s a planned phase that begins before your cycle ends. Your PCT protocol will depend on which anabolic androgenic steroids you ran, the duration, the dosage, and how suppressed your axis is. This guide gives you the framework to build yours correctly.

What Happens to Your Hormones
During & After a Cycle
Understanding the physiology makes the protocol make sense. Here’s what’s happening inside your endocrine system from the first pin to post-PCT clearance.
Exogenous Androgens Enter
AAS flood androgen receptors. Blood testosterone rises far above natural levels. The brain detects excess and begins shutting down endogenous production.
HPG Axis Shuts Down
The hypothalamus stops releasing GnRH. The pituitary halts LH and FSH output. Without those signals, the testes reduce testosterone synthesis — and can atrophy.
The Dead Zone
Cycle ends. Exogenous testosterone clears. But the axis is still suppressed. Testosterone crashes. Estrogen is relatively high. This is when you feel worst and lose the most.
PCT Restarts the System
SERMs block estrogen at the pituitary, triggering a surge in LH and FSH. The testes receive the signal and restart testosterone production on an accelerated timeline.
PCT Drugs Explained:
SERMs, AIs & Support
These are the tools. Know what each one does, when to use it, and what dose range you’re working in.
Tamoxifen (Nolvadex)
The most common PCT SERM. Blocks estrogen receptors at the pituitary, causing a spike in LH and FSH that drives testosterone recovery. Well-tolerated at standard doses.
- Start at 40mg/day weeks 1–2, drop to 20mg/day weeks 3–4
- Can be used solo for mild to moderate cycles
- Watch for vision side effects — rare but discontinue if they appear
Clomiphene (Clomid)
Stronger LH stimulus than Nolvadex but harsher on mood and vision at higher doses. Often stacked with Nolvadex for heavy or prolonged cycles.
- 50mg/day weeks 1–2, 25mg/day weeks 3–4
- More mood side effects — lower dose where possible
- Strong choice after long multi-compound cycles
Anastrozole (Arimidex)
Used during the cycle to control estrogen, not typically during PCT itself. If estrogen is rebounding high post-cycle, a low dose AI may be warranted before starting SERMs.
- Don’t crash estrogen — you need some for joint health and mood
- Adjust based on bloodwork — don’t dose blind
- Taper off before starting SERMs, not alongside them
SERM Comparison: Nolvadex vs Clomid
| Factor | Nolvadex (Tamoxifen) | Clomid (Clomiphene) |
|---|---|---|
| LH Stimulus | Moderate | Strong |
| Mood Side Effects | Mild | Notable at higher doses |
| Vision Risk | Low | Higher — rare but real |
| Best For | Standard cycles, solo use | Heavy / long cycles, stacked with Nolva |
| Starting Dose | 40mg/day → taper to 20mg | 50mg/day → taper to 25mg |
| Duration | 4–6 weeks | 4–6 weeks |
What Happens If You Skip PCT
Skipping PCT isn’t a gamble — it’s a guarantee of a bad outcome. The severity depends on cycle length and compounds used, but the pattern is consistent.
- Testosterone suppression lasting up to 12 months
- Elevated estrogen relative to testosterone
- Gynecomastia development or worsening
- Testicular atrophy — may not fully reverse without intervention
- Rapid muscle loss as cortisol dominates low-testosterone environment
- Significant fat gain — especially around the midsection
- Persistent fatigue, low energy, poor sleep quality
- Depression, irritability, loss of drive
- HPG axis restores within 6–12 weeks
- Majority of muscle and strength gains retained
- Mood, libido, and energy stabilise within weeks 2–3
- Bloodwork confirms recovery — no long-term damage
Critical Warning Signs
These symptoms during the post-cycle window mean you need to start PCT immediately — not wait:
- Visible or tender breast tissue (gyno onset)
- Severe depression or mood crashes
- Complete loss of libido beyond week 2
- Rapid muscle softening and strength loss
- Run bloodwork to confirm low T before adjusting
- Start Nolvadex 20–40mg/day immediately
- Reduce training volume temporarily — recover first
The PCT Protocol
This is the standard framework. Adjust timing based on your ester — short esters clear faster, long esters like Enanthate or Cypionate need the full 2-week wait.
Complete Your Cycle
Run your cycle as planned. In the final week, ensure you have your PCT medications on hand. Do not extend the cycle to delay PCT — suppression compounds with time.
Wait for Clearance (1–2 Weeks)
Long esters (Enanthate, Cypionate): wait 14 days after last injection. Short esters (Propionate): wait 3–4 days. Starting PCT too early wastes the SERM — exogenous test will suppress the axis right back down.
Begin SERMs — Weeks 1–2 (High Dose)
Nolvadex 40mg/day OR Clomid 50mg/day (or both for heavy cycles). This aggressive opening drives an LH spike and gets the testes working again fast. Some users add hCG here if atrophy is significant.
Taper SERMs — Weeks 3–4 (Standard Dose)
Drop to Nolvadex 20mg/day OR Clomid 25mg/day. Testosterone is rising, the axis is coming back online. Maintain the taper for another 2 weeks. Some extend to 6 weeks for heavier cycles.
Post-PCT Bloodwork — Week 10–12
4–6 weeks after the last SERM dose, run a full hormone panel: total testosterone, free testosterone, LH, FSH, estradiol, SHBG, liver enzymes, lipid profile, and hematocrit. This confirms full recovery.
PCT Dosing Schedule at a Glance
| Week | Nolvadex | Clomid (if stacking) | Notes |
|---|---|---|---|
| Week 1–2 | 40mg/day | 50mg/day | High-dose phase — aggressive LH stimulus |
| Week 3–4 | 20mg/day | 25mg/day | Taper phase — axis stabilising |
| Week 5–6 | 20mg/day (if needed) | — | Extension for heavy or long cycles only |
| Week 10–12 | — Off — | Run bloodwork to confirm recovery | |
Your PCT Recovery Timeline
SERMs Kick In
LH and FSH begin rising within 48–72 hours of first SERM dose. Expect some mood fluctuation and libido changes as hormone levels shift.
Testosterone Rising
Natural testosterone production resumes. Energy starts returning. Libido improving. Some muscle fullness returning as T climbs. Mood stabilises.
Approaching Baseline
Testosterone nearing pre-cycle baseline. Training performance stabilised. Most gains retained. Final SERM taper complete by end of this phase.
Full Recovery
Bloodwork confirms testosterone, LH, and FSH at natural baseline. Axis fully restored. You’re clear to assess next cycle or continue natural training.
Bloodwork: When to Test & What to Check
Running PCT without bloodwork is like driving blind. Three panels — pre-cycle, mid-PCT, and post-PCT — give you everything you need to manage your recovery intelligently.
Before You Start
Establish your natural numbers. Total T, free T, LH, FSH, estradiol, SHBG, liver enzymes (AST/ALT), lipid panel, hematocrit, and CBC. You need this baseline to measure recovery against.
Progress Check
Testosterone, LH, FSH, and estradiol. Confirm the axis is responding to SERMs. If LH is still flat, you may need to extend or adjust dose. Catch problems here, not after.
Clearance Panel
Full panel 4–6 weeks after last SERM dose. Testosterone back to your personal baseline, LH and FSH normal, liver values clean, lipids recovering. This is your green light.
Key Markers & Target Ranges (Post-PCT)
| Marker | Target Post-PCT | What It Tells You |
|---|---|---|
| Total Testosterone | 300–900+ ng/dL (your baseline) | Primary indicator of axis recovery |
| LH | 1.7–8.6 IU/L | Confirms pituitary is signalling testes |
| FSH | 1.5–12.4 IU/L | Testicular function and sperm recovery |
| Estradiol (E2) | 20–40 pg/mL | Ensure no estrogen rebound or crash |
| AST / ALT | Within normal lab range | Liver health — especially after oral compounds |
| Hematocrit | <52% | Red blood cell elevation — cardiovascular risk marker |
How to Train, Eat & Live
During PCT
The drugs do part of the work. What you do outside of them determines whether you keep your gains or lose them. PCT is an active phase, not a rest phase.
Training
Reduce volume by 20–30%. Keep intensity. Your recovery capacity is lower — train hard, not long. Strength will dip slightly; that’s normal and temporary.
Protein & Calories
Keep protein high — 1g per lb of bodyweight minimum. Slight caloric surplus or maintenance. This is not the time to cut — you need fuel for hormonal recovery.
Sleep
The majority of testosterone production happens during deep sleep. 7–9 hours is not optional during PCT. Poor sleep actively suppresses the recovery process.
Vitamin D3 & Zinc
Canadian winters mean chronically low D3. Both D3 and zinc are directly involved in testosterone synthesis. Supplement: 3000–5000 IU D3 daily, 25–45mg zinc.
PCT Myths vs Reality
You only need PCT if you ran a long or heavy cycle
Suppression begins within the first week of any AAS use. Even short 6-week cycles cause measurable HPG axis shutdown. PCT is required every time, no exceptions.
The body will recover on its own — PCT is just extra
It will eventually recover — but over 12 months of low testosterone with muscle loss, fat gain, and depression is the cost of skipping PCT. That’s not a trade worth making.
Running higher SERM doses means faster recovery
Dosing above the therapeutic range increases side effects without proportional benefit. The recovery timeline is determined by your axis sensitivity, not how hard you hit the Clomid.
How Canadian Athletes
Ran Their PCT
Two different approaches from two different athletes — both got their bloodwork done, both came out the other side intact.
First Cycle: 12-Week Testosterone Enanthate @ 400mg/wk
Ran Anastrozole at 0.5mg every other day throughout the cycle to keep estrogen in range. Two weeks after the last pin, started Nolvadex at 40mg/day.
By week 3 of PCT, libido and energy were mostly back. Dropped to 20mg/day for weeks 3–4. Ran bloodwork at week 10 post-cycle — total testosterone at 520 ng/dL, LH and FSH both in normal range. Full recovery confirmed. Retained approximately 80% of cycle gains.
20-Week Bulk: Test + Deca, Winter Off-Season
Planned the cycle deliberately to end in November, giving a full winter to recover before spring prep. Because Deca (nandrolone) is more suppressive than testosterone alone, he ran hCG at 500 IU twice per week during the final 4 weeks of the cycle to prevent severe testicular atrophy.
After a 2-week clearance period, started Clomid 50mg + Nolvadex 20mg daily for 4 weeks, then Nolvadex 20mg solo for 2 more weeks. Added ZMA and 4000 IU D3 daily. Bloodwork at week 14 post-cycle showed full recovery. Ready for spring prep on schedule.
Complete PCT Checklist:
From Last Pin to Clearance
Have Your PCT Meds Before Your Cycle Ends
Nolvadex, Clomid, and any support supplements should be sourced before you pin the last dose. You don’t want to be scrambling during the wait period.
Run hCG During Final Weeks (If Suppression Is Severe)
500 IU hCG twice per week for weeks 10–12 of a 14-week cycle keeps the testes primed and reduces recovery time. Stop hCG before starting SERMs.
Wait for Ester Clearance (1–2 Weeks)
Long esters: 14 days. Short esters: 3–5 days. Starting SERMs too early while testosterone is still elevated in blood will negate the protocol entirely.
Start SERMs — High Dose First Two Weeks
Nolvadex 40mg/day or Clomid 50mg/day. Heavy cycles: stack both. This is the most critical phase — do not skip or reduce the opening dose.
Taper Weeks 3–4 (or 3–6 for Heavy Cycles)
Drop to Nolvadex 20mg/day or Clomid 25mg/day. Continue supporting sleep, protein intake, and D3/zinc supplementation throughout this phase.
Confirm Recovery With Bloodwork at Week 10–12
Full hormone panel 4–6 weeks after last SERM dose. If testosterone and LH are back at your pre-cycle baseline, you’re recovered. If not, investigate before running another cycle.
Don’t Leave Your Gains
On the Table
PCT is the last part of the cycle — and the most important. Get your SERMs, run your bloodwork, and come out the other side with your testosterone intact and your gains kept.
