peptides testosterone FAQ

HCG alone preserves fertility in 50–65% of men on TRT, which is better than the 8% success rate with testosterone monotherapy. Adding recombinant FSH (not a peptide, but mechanistically necessary for spermatogenesis) increases that figure to 75–80%. The protocol: HCG 250 IU every other day + FSH 75 IU three times weekly. Monitor semen analysis every 12 weeks. If sperm count remains above 5 million/mL, the protocol is working. If counts drop below 1 million/mL after six months, consider stopping testosterone entirely and switching to enclomiphene monotherapy (12.5–25mg daily), which maintains testosterone while preserving endogenous production.

Add enclomiphene 12.5 mg every other day to maintain LH signaling during the SARM cycle, or reduce RAD-140 to 5 mg daily and assess whether anabolic effects remain sufficient. Research from 2021 published in Andrology demonstrated that enclomiphene co-administration preserved LH levels at 80% of baseline in subjects using anabolic steroids—the same principle applies to SARMs. The enclomiphene blocks estradiol feedback at the hypothalamus, preventing the suppressive signal that RAD-140's androgenic activity would otherwise trigger. Post-cycle, discontinue the SARM and continue enclomiphene for 4 weeks to accelerate LH recovery.
