As of January 1, 2026, human chorionic gonadotropin (hCG) is no longer a controlled substance in California. For nearly 40 years, California was one of the only places in the country that classified this common fertility and hormone medication as a Schedule III controlled substance, in the same legal category as anabolic steroids. A new state law, AB 1152, changed that.
For men on TRT, hCG is one of the main tools used to protect fertility and testicular function during testosterone therapy, and California’s classification made it harder to prescribe than almost anywhere else.
But, a separate federal rule has made hCG hard to get nationwide since 2020, and that part has not changed. This guide covers what California’s new law does, why the state treated hCG this way for so long, the federal supply issue that still applies, how hCG compares to the alternatives your clinic may offer, and how to actually get it in 2026.
Is hCG a Controlled Substance in California?
No. As of January 1, 2026, hCG is no longer a controlled substance in California. A state law called AB 1152 removed it from California’s list of Schedule III controlled substances, where it had sat since 1986. hCG is still a prescription medication, so you continue to need a valid prescription from a licensed provider to obtain it. The change removes the controlled-substance restrictions while keeping the prescription requirement in place.
What Changed Under AB 1152
AB 1152, authored by Assembly member Joe Patterson, removed hCG from California’s Schedule III list. Governor Newsom signed it in October 2025, and it was chaptered as Chapter 183 of the Statutes of 2025. Because it was a standard, non-urgency bill, it took effect on January 1, 2026. From that date, California regulates hCG the way federal law and most other states already do, as a normal prescription drug.
Here is the change at a glance:
- Bill: AB 1152 (Assembly member Joe Patterson)
- What it does: Removes hCG from California’s list of Schedule III controlled substances
- Signed: October 2025, as Chapter 183, Statutes of 2025
- Effective: January 1, 2026
Why was hCG a controlled substance in California?
California added hCG to Schedule III in 1986, grouping it with anabolic steroids and testosterone. The reasoning at the time was tied to doping, hCG can stimulate natural testosterone production, so anabolic steroid users sometimes used it to restart their own hormone output, and regulators wanted to discourage that misuse.
The issue is that the federal government and nearly every other state never treated hCG as a controlled substance, because the risk of abuse or public harm is very low and the medication has well-established medical uses. California was the outlier.
Under the old rule, possessing hCG outside the controlled-substance requirements could even carry criminal exposure, a heavy consequence for a fertility hormone.
What The Change Means if You’re on TRT
The practical effect is that hCG becomes easier to prescribe and obtain in California, and it sheds the extra restrictions that came with controlled-substance status. In real terms:
- Fewer prescribing hurdles: Providers no longer have to handle hCG under the stricter controlled-substance framework.
- No controlled-substance reporting: hCG prescriptions are no longer tracked in California’s controlled-substance monitoring system.
- No possession exposure: The criminal-possession risk tied to its old classification is gone.
- Easier continuity: Filling and refilling hCG now works more like a standard prescription.
None of this changes the medicine itself or the need for medical supervision. It changes the paperwork and the legal category around it.
Why hCG Has Still Been Hard to Get in the US
In March 2020, the FDA reclassified hCG as a biologic, which removed it from the substances that local compounding pharmacies can make under the common 503A pathway. Almost overnight, most compounding pharmacies could no longer produce hCG.
That left two supply routes, each with drawbacks:
- Brand-name hCG (Pregnyl, Novarel) stayed on the market, but at higher cost, with insurance hurdles and periodic supply limits.
- 503B outsourcing facilities, a smaller category of FDA-registered compounders, can still make hCG, though only a limited number actually do.
Because hCG became harder and pricier to source, many TRT clinics switched patients to gonadorelin, a different medication that could still be compounded easily. That switch was driven by access and cost, and it happened quickly, often without much explanation to patients. If you started TRT after 2020, you may have been offered gonadorelin without ever being told hCG existed as an option.
California removing hCG from its controlled-substance list clears the state legal barrier, while the federal compounding situation is a separate issue that still affects supply and price. hCG remains available through brand-name products and 503B facilities, and some compounding access has improved over time.
hCG vs. Gonadorelin vs. Enclomiphene
If your goal is protecting fertility or testicular function on TRT, hCG is one of three options a clinic might use. They act at different points in the same hormonal chain.
| hCG | Gonadorelin | Enclomiphene | |
| How it works | Mimics LH and acts directly on the testes (downstream) | Signals the pituitary to release LH and FSH (upstream); needs an intact pituitary | Blocks estrogen feedback so the pituitary releases more LH and FSH |
| Main role | Preserve testicular size, intratesticular testosterone, and fertility during TRT | Preserve testicular function during TRT | Raise natural testosterone, often as an alternative to TRT |
| Evidence on TRT | Strongest for maintaining intratesticular testosterone | Limited, mostly extrapolated from other conditions | Moderate, raises testosterone and supports sperm |
| Dosing | Injection, a few times a week | Injection, often daily because of its pulsatile biology | Oral, daily |
| Availability | Brand or 503B compounded, tighter since 2020 | Easy to compound, widely available | Prescription, generally available |
hCG has the strongest evidence for fertility preservation during TRT, gonadorelin is easier to obtain but less proven for this use, and enclomiphene is usually a path for men who want to raise testosterone without starting TRT.

Should You Switch From Gonadorelin Back to hCG?
If your clinic put you on gonadorelin after 2020 because hCG was hard to get, the California change is a reason to revisit that decision with your provider, though it is not automatically the right move for everyone.
- If fertility is a current or near-future goal, hCG has the stronger evidence base, and switching is often worth discussing.
- If you are mainly maintaining testicular size and feel fine on gonadorelin, there may be no urgent reason to change.
- If you tried gonadorelin and noticed less benefit, some men report a more noticeable response on hCG, which is worth raising.
The right answer depends on your goals and your labs, so bring it to your next visit and decide with your provider.
Do you still need a prescription for hCG in California?
Yes. Removing hCG from the controlled-substance schedule does not make it available over the counter. hCG remains an FDA-regulated prescription medication, so you still need an evaluation and a prescription from a licensed provider.
That prescription requirement is what guards against misuse, which was part of the argument that the controlled-substance label was unnecessary in the first place.
Why hCG matters for men on TRT
hCG is valuable in testosterone therapy because of how TRT affects the testes. The mechanism runs in three steps:
- TRT suppresses your natural signals: Taking testosterone from outside the body tells your brain to cut back on LH and FSH, the hormones that keep your testes active.
- Intratesticular testosterone falls: Without LH, the testosterone made inside the testes drops sharply, which can shrink them and impair sperm production.
- hCG stands in for LH: It keeps the testes stimulated, preserving testicular size, intratesticular testosterone, and fertility while a man is on TRT.
This is why hCG is often paired with testosterone for men who care about fertility or want to avoid testicular shrinkage. For a fuller picture, see our guide to TRT and fertility.
Next Steps: Getting hCG in California in 2026
The state legal barrier is gone, and the steps are the same as any prescription hormone, with one supply precaution:
- See a licensed provider for an evaluation and, where relevant, bloodwork.
- Get a prescription if hCG fits your goals, whether for fertility, testicular preservation, or as part of a TRT protocol.
- Fill it through the right pharmacy: Because of the 2020 compounding rules, hCG usually comes as a brand-name product or through a 503B outsourcing facility, so ask your provider where yours will be filled and what it will cost.
If hCG is difficult to source for your situation, your provider can discuss whether gonadorelin or another option fits, though hCG remains the better-supported choice when fertility is the priority.
