Post cycle therapy is a sequencing problem, not a list of pills. This tool scores how suppressed your axis actually is based on every compound, dose and week you ran, then works out when to start, whether your testes need priming first, what the taper looks like, and which labs confirm you recovered.
Expect roughly 8–13 weeks to feel normal again after PCT, longer if bloodwork lags.
Your longest-acting compound needs ~15 days to clear. Start earlier and the SERMs are wasted, because the exogenous androgen still in your blood keeps the axis shut down.
Taken daily. Nolvadex also blocks estrogen at breast tissue, so it covers gyno without an AI. Enclomiphene, Clomid's active isomer, is an option if Clomid mood or vision effects hit hard.
Do not run an aromatase inhibitor during PCT unless you have real high-estrogen symptoms. You need estrogen to recover: it drives LH and libido, and crashing it here stalls the whole process and wrecks your mood. The SERM already handles gyno risk.
Educational framework built from reported protocols and pharmacology, not medical advice and not a prescription. SERMs and hCG are prescription medicines; misuse carries real risks. Recovery varies with genetics, age, and cycle history. Bloodwork and a qualified clinician, ideally one who understands this context, should guide any real protocol.
Starting too early wastes the entire protocol. Selective estrogen receptor modulators work by removing estrogen's negative feedback so the brain resumes signalling. If exogenous testosterone is still circulating from a long ester, the axis cannot sense any drop and nothing restarts. You spend four weeks on drugs for nothing.
Under treating heavy suppression is the other. A sixteen week run with nandrolone at high doses is not the same problem as eight weeks of low dose testosterone, and treating them identically leaves some people in prolonged hypogonadism.
The tool takes the longest acting compound you ran and computes its clearance window, then sets your start day from that. Short esters clear in days, enanthate and cypionate need roughly two weeks, and nandrolone or Sustanon closer to three. That single number is the most important output on the page. Cross-check your own protocol first with the Serum Testosterone Level Calculator if you are unsure which ester is still active.
Human chorionic gonadotropin mimics luteinising hormone and directly stimulates the testes. That makes it useful for priming testicular function during the clearance window, but it also suppresses your own axis through feedback, which means running it alongside SERMs works against the recovery you are trying to produce. The tool sequences it correctly and stops it before the taper begins. See the hCG Dosage Calculator for exact reconstitution and units.
Estrogen is part of the recovery signal. Crushing it during PCT stalls the process and makes you feel considerably worse. The SERM already protects against gynecomastia, so an aromatase inhibitor is generally unnecessary and often counterproductive here — see the Estradiol & Aromatase Inhibitor Calculator for why.
Once the taper finishes, confirm recovery with bloodwork rather than by feel — run your post-PCT panel through the Bloodwork Analyzer to see LH, FSH and testosterone read together instead of one at a time.
After the longest ester you ran has cleared. That is roughly four days for propionate, two weeks for enanthate or cypionate, and about three weeks for nandrolone or Sustanon. Starting before then wastes the protocol because the axis cannot sense the drop.
Four weeks is standard for mild to moderate suppression. Longer or heavier cycles, particularly those involving nandrolone or trenbolone, commonly need six to eight weeks. The right length scales with how suppressed you actually are.
Tamoxifen is milder and better tolerated, and is sufficient for most standard cycles. Clomiphene is stronger but carries more mood and visual side effects. Heavier suppression often warrants both together at reduced doses. Enclomiphene is clomiphene's active isomer and is better tolerated by some people.
It is most useful after long cycles, high doses or nineteen nor compounds, where testicular function has been shut down for an extended period. It must be run and finished before SERMs begin, not alongside them, because it suppresses the axis you are trying to restart.
Bloodwork, six to eight weeks after the protocol ends. Test luteinising hormone, follicle stimulating hormone, total and free testosterone and estradiol. Feeling normal is encouraging but it is not proof, and low testosterone with low LH at that point means the axis has not restarted and needs medical attention.
