Shop by category

Post-cycle therapy (PCT) is the catalog's name for this group, which holds one product, HCG. The name is a shopping label. It is not one of the uses on hCG's approved labels, as the first question below explains. Health Canada's April 2026 warning about injectable peptides bought online named HCG among unauthorized products, and said such products may contain too much, too little or none of the active ingredient, unlisted ingredients, or contaminants such as solvents, heavy metals and particles.7

HCG's prescription status is covered on hormone therapy peptides. The HCG education page sets out the label and the research, and the testosterone goal guide maps related compounds.

Frequently asked questions

Is HCG approved for post-cycle therapy?

No. The approved uses of urinary hCG are prepubertal undescended testes not caused by an obstruction, selected cases of hypogonadotropic hypogonadism in males, and induction of ovulation and pregnancy in certain anovulatory infertile women, with a prescriber setting each dose.12 Post-cycle use is not among them. The HCG vial in this category is a research product labeled: For research use only. Not for human or veterinary use.

Is HCG banned in sport?

Yes, for men. WADA's 2026 Prohibited List, in effect from January 1, 2026, bans chorionic gonadotrophin in males at all times, in and out of competition, under S2.2.1, testosterone-stimulating peptides, as a non-Specified Substance.345 The same class names kisspeptin and gonadorelin, which are sold under reproductive health peptides.8

In New York it is: the state lists chorionic gonadotropin in Schedule III of its controlled substances schedules, under Public Health Law section 3306.6 The sources behind this page do not cover federal scheduling or the laws of other states, so check the rules where your lab operates before you order.
