Thymosin alpha-1 has been tested in controlled trials in people, mostly in Asia, for hepatitis B, sepsis and other serious illnesses.
Thymosin alpha-1 is not FDA-approved for any use. These studies don’t show that it treats any condition in people, and safety data in people are limited. Your free consultation with a nurse practitioner is the place to talk through what is and isn’t known.
Most peptides are not FDA-approved for the uses discussed publicly, and are prescribed at the discretion of a licensed provider after an individual evaluation. A peptide is not appropriate for everyone, and individual results vary.
Peptide therapy at Cienega Medical is available by prescription only. You start with a consultation with one of our nurse practitioners, who reviews your health history, your goals, and whether a peptide is appropriate for you. If it is, they write the prescription and we prepare it for your visit. If it is not, they will tell you that too.
Thymosin alpha-1 (thymalfasin) is a synthetic peptide studied in immunology research.
In the U.S. it is not FDA-approved and is classified as a research peptide.
A synthetic version is registered as a pharmaceutical in a number of other countries.

Thymosin alpha-1 (also written Tα1 or thymalfasin) is a 28-amino-acid peptide fragment that was first identified in extracts of the thymus gland. It is now made synthetically and has been studied in laboratory and clinical research on the immune system. A free consultation with a nurse practitioner is the place to discuss that research in relation to your immune-health concerns.
No. Thymosin alpha-1 is not approved by the U.S. Food and Drug Administration. A synthetic form is registered as a pharmaceutical product in some other countries, but regulatory status differs by jurisdiction. Your nurse practitioner can explain what that means when considering a prescription at your free consultation.
Thymosin alpha-1 is not right for everyone. Your nurse practitioner reviews your health history, current medications and existing conditions before prescribing and will tell you if it is not a fit. Bring your current medication list to your free consultation.
Bottle prices are listed on this page. Every order includes one medication review fee, which covers the review and managing your prescriptions, and is charged once even when prescriptions go out as separate orders the same day. The consultation itself is free.
Pick a time for a free telehealth visit with a nurse practitioner, by phone or video. Before your visit, you fill out a short health form. They go through your health history, your current medications and what you are trying to achieve, then tell you whether this is a sensible fit. Not everyone is, and if you are, they write the prescription and you pay for your bottles plus one medication review fee.
Your prescription is filled by a licensed U.S. 503A compounding pharmacy.
That depends on what your provider prescribes, so it is not something we can put a number on here. Your nurse practitioner tells you at your review roughly how long a bottle should last for you and when it would make sense to order again. You can order as many bottles as your nurse prescribes while you’re on the call, and when you need more, book another call online or call us. Each call where you order adds one $49 medication review. Nothing renews on its own. If you’d like bottles sent on a regular schedule, ask your nurse: it’s worked out case by case, since everyone’s prescription is different.
Both. Collect at West Hollywood, Santa Monica or Calabasas, where we pack it for you and show you how to inject it, all covered by the medication review fee. Or we ship it to your home anywhere in California, at no extra charge.
