Post Cycle Therapy (PCT) is the protocol you run after a steroid cycle to help restore your body's natural testosterone production. Skip PCT and you risk prolonged low testosterone, muscle loss, depression, libido issues and potentially permanent hormonal damage.
This guide covers everything: why PCT is essential, which SERMs to use (Nolvadex vs Clomid), exact dosing protocols for different cycle types and when to start.
Why Do You Need PCT?
Anabolic steroids suppress your body's natural testosterone production by signaling the hypothalamic-pituitary-gonadal (HPG) axis to stop producing LH (Luteinizing Hormone) and FSH (Follicle Stimulating Hormone). Without these signals, your testes reduce or stop testosterone production entirely.
When you stop your cycle, exogenous testosterone levels drop — but your natural HPG axis hasn't recovered yet. This leaves you in a state of low testosterone, which causes muscle loss, fat gain, mood crashes, fatigue and sexual dysfunction. PCT speeds up the recovery of this axis to weeks rather than months.
When to Start PCT
The timing depends on the esters in your cycle. You need to wait for the exogenous steroids to clear before starting PCT — starting too early means the SERMs are fighting against still-active androgens.
| Compounds Used | Wait Before Starting PCT |
|---|---|
| Short esters only (Prop, Ace) | 3–4 days after last injection |
| Long esters (Enanthate, Cypionate) | 14 days after last injection |
| Oral only (Anavar, Dbol) | 24–48 hours after last dose |
| Long + short ester mix | 14 days after last long ester injection |
| Deca Durabolin (Nandrolone) | 21 days after last injection |
Nolvadex vs Clomid: Which is Better?
Nolvadex (Tamoxifen) is a Selective Estrogen Receptor Modulator (SERM) that blocks estrogen receptors at the pituitary, allowing LH and FSH to rise and stimulate natural testosterone production. It is better tolerated than Clomid and is the first choice for most users.
Clomid (Clomiphene) is also a SERM but acts on both estrogen receptor alpha and beta. It's generally more aggressive and can cause more side effects (visual disturbances, mood swings) but is useful for heavier cycles requiring stronger hormonal recovery.
💡 For most single-compound cycles (e.g., testosterone only), Nolvadex alone is sufficient. For multi-compound cycles or long cycles (16+ weeks), combining both Nolvadex + Clomid produces faster recovery.
PCT Protocols
Standard PCT — Nolvadex Only (most cycles)
- Week 1–2: Nolvadex 40mg/day
- Week 3–4: Nolvadex 20mg/day
Aggressive PCT — Nolvadex + Clomid (heavy/long cycles)
- Week 1–2: Nolvadex 40mg/day + Clomid 50mg/day
- Week 3–4: Nolvadex 20mg/day + Clomid 25mg/day
Clomid Only Protocol (alternative)
- Week 1: Clomid 100mg/day
- Week 2–3: Clomid 50mg/day
- Week 4: Clomid 25mg/day
Should You Use HCG?
HCG (Human Chorionic Gonadotropin) mimics LH and can be used during the cycle (not during PCT) to prevent testicular atrophy and keep the HPG axis more primed for recovery. Using HCG at 250–500 IU twice weekly during your cycle makes PCT easier and more effective. Stop HCG before beginning SERMs.
Supplements During PCT
- Zinc: Essential for testosterone production
- Vitamin D3: Correlated with healthy testosterone levels
- Ashwagandha: May help reduce cortisol and support testosterone
- TUDCA/UDCA: If you ran an oral steroid, liver support during PCT is advisable
- Omega-3: Helps restore HDL cholesterol damaged during cycle
Signs PCT is Working
Within 2–3 weeks of starting a proper PCT, you should notice: improved mood, returning libido, better sleep quality and reduced fatigue. If symptoms of low testosterone persist beyond 4–6 weeks post-PCT, consider getting bloodwork done to check LH, FSH and total/free testosterone levels.
