PCT Basics
Post-cycle therapy is how you help your body restart its own testosterone production after a cycle. Skipping it is not an option unless you are on TRT or blasting and cruising.
The common SERMs
- Nolvadex (Tamoxifen): The most widely used PCT drug. Typical protocol: 20mg per day for 4 to 6 weeks. Stimulates LH and FSH release from the pituitary.
- Clomid (Clomiphene): An alternative to Nolvadex. Typical protocol: 25 to 50mg per day for 4 to 6 weeks. Some users report more mood-related side effects with Clomid compared to Nolvadex.
You do not need to run both. Pick one. Most experienced users lean toward Nolvadex for its milder side effect profile.
Timing
When you start PCT depends on the ester you used:
- Short esters (Propionate, Acetate): start PCT 3 to 5 days after your last injection
- Medium esters (Enanthate, Cypionate): start PCT 14 to 18 days after your last injection
- Long esters (Undecanoate, Decanoate): start PCT 21 to 28 days after your last injection
The idea is to let the exogenous hormone clear your system before you start stimulating natural production. Starting too early means the SERM competes with the remaining exogenous testosterone. Starting too late means you spend extra time in a suppressed state.
What recovery looks like
Energy and mood often dip in the first two weeks of PCT. Libido may drop. Strength in the gym may stall or decrease slightly. This is normal. Your body is recalibrating. It gets better. By week 4 to 6, most users feel close to baseline.
Post-PCT bloodwork
Get bloods 4 to 6 weeks after finishing PCT to confirm recovery. Compare LH, FSH, total testosterone and free testosterone to your pre-cycle baseline. If values are still significantly suppressed, consult a doctor. Read the bloodwork guide for what to test and how to interpret it.
