The short answer
Compounded HCG went away because of a change in its legal category, not because of a safety problem with the hormone itself. On March 23, 2020, HCG and a group of other protein medicines were reclassified as biological products, and federal law gives compounding pharmacies no pathway to make biologics. The FDA-approved brands survived; the lower-cost pharmacy-made versions did not.
For men on testosterone therapy, that turned a once-inexpensive add-on into a brand medicine. It also pushed some men toward sources that are neither licensed nor safe, which is the part of the story worth knowing before you buy anything.
What changed on March 23, 2020?
A 2009 law set the date years in advance. The Biologics Price Competition and Innovation Act said that certain protein products approved as ordinary drugs would be deemed to hold biologics licenses as of March 23, 2020. The FDA’s list of products deemed to be biologics on that date includes chorionic gonadotropin products such as Pregnyl and Novarel.
In a notice to compounders published that March, the FDA said that beginning March 23, the transitioning products would not be eligible for the compounding exemptions in sections 503A and 503B of the Food, Drug, and Cosmetic Act. The agency named human chorionic gonadotropin as one of four bulk substances that outsourcing facilities had reported using, alongside hyaluronidase, FSH and menotropins.
Why can’t a pharmacy compound a biologic?
The compounding exemptions were written for drugs, and biologics sit under a different law. The FDA’s compounding questions and answers put it plainly: biological products are not eligible for the 503A or 503B exemptions, and federal law provides no legal pathway for biologics prepared outside an approved biologics license.
The FDA has published narrow guidance on when certain licensed biologics may be mixed, diluted or repackaged. That is very different from making HCG from bulk powder, which is what compounded HCG was. Our article on 503A versus 503B compounding pharmacies explains how the two pharmacy types differ.
Why did men on TRT use HCG in the first place?
HCG stands in for a signal that testosterone therapy switches off. The Pregnyl label describes HCG’s action as virtually identical to pituitary LH, the hormone that tells the testes to make testosterone. When a man takes outside testosterone, his own LH falls, testosterone inside the testes drops, and sperm production and testicular size often follow.
Adding HCG aims to keep the testes working. In a small retrospective study of 26 men on testosterone who also used low-dose HCG every other day, none became azoospermic during follow-up and 9 contributed to a pregnancy. That is encouraging but limited evidence, and using HCG alongside testosterone is off-label. The labeled uses in men are prepubertal cryptorchidism and selected cases of hypogonadotropic hypogonadism.
HCG is not for everyone either. The Pregnyl label lists prostate or breast tumors, tumors of the hypothalamus or pituitary, and uncontrolled thyroid, adrenal or pituitary disorders among its contraindications, and it notes that HCG may occasionally cause breast enlargement in men. Those are questions for the evaluation, not for a website checkout.
What do men use now?
Men who still want HCG use a licensed product, and men who cannot get it or do not need it have a few other paths:
| Option | What it is | What to know |
|---|---|---|
| Licensed HCG (Pregnyl and similar) | Brand biologic from the manufacturer | Powder mixed with diluent; the label says a mixed vial stays stable 60 days in the refrigerator and lists intramuscular use |
| HCG on its own, without testosterone | Uses the body’s own production | Can suit men with a pituitary-signal problem who want to protect fertility |
| Testosterone without HCG | Standard therapy | Fine for many men who are not planning children, with the trade-offs explained first |
| Other fertility-sparing approaches | Medicines such as clomiphene, used off-label | Chosen with a clinician based on LH, FSH and goals |
Clomiphene’s labeled use is inducing ovulation in women, and MedlinePlus lists male infertility among its other uses beyond that label, so it is a judgment call rather than a standard swap.
The cost shift is real. Licensed HCG is priced as a brand medicine, and our page on HCG cost for men breaks down what drives the monthly total, while why HCG is hard to get covers supply. For a side-by-side of the two approaches, see HCG versus TRT, and for the pituitary-based option, our page on clomiphene for men.
What this means for men right now
The practical lesson is to treat any non-licensed HCG as a red flag. A vial from a website, a gym contact or a “research chemical” seller has no regulatory route to exist legally as compounded HCG anymore, so there is no assurance of what it contains or how it was made. HCG drops sold for weight loss are a separate problem; the Pregnyl label states that HCG has not been shown to be effective treatment for obesity, a point our page on HCG for weight loss covers.
If you were on compounded HCG years ago and switched, it is worth asking whether you still need it. Goals change, and a man who wanted fertility at 34 may have a different plan at 42.
A few habits make any HCG conversation easier:
- Bring the exact product names and doses you have used, including old pharmacy records or vial details from compounded products.
- Note when you started and stopped, and any breast tenderness, mood change or testicular ache along the way.
- Throw out leftover compounded vials rather than mixing them into a new plan.
- Ask how a licensed vial will be mixed, stored and timed around your testosterone doses.
How Ultimate Male uses HCG today
HCG appears on the Ultimate Male menu as Pregnyl, a licensed product, used either on its own for some men or alongside a testosterone plan. Our page on HCG with testosterone therapy explains when each fits, and the guide to mixing and injecting HCG shows the routine at home.
The decision starts with labs and a one-on-one consultation with a PA-C or MD at our San Gabriel or Downey clinic, where fertility plans, testicular symptoms and cost are all discussed before anything is ordered. If HCG is part of your testosterone therapy, follow-up labs show how your body responds; lab monitoring on HCG describes the markers involved. Start with the free 10-minute call.
