IGF-1 LR3 is prescribed after a consultation and is one of the more advanced options, so provider guidance matters.
Experienced, training-focused adults pursuing strength and lean mass

Anyone who prefers close provider oversight on an advanced protocol
A free consultation with our medical team is required to see if it is appropriate for you.
IGF-1 LR3 is a modified version of insulin-like growth factor 1, engineered to stay active in the body longer than the natural form. IGF-1 is one of the main signals through which growth hormone drives tissue growth and repair. Research and clinical interest focus on muscle growth, recovery, and metabolic support. It is a research peptide, prescription-only.
Muscle growth and lean-tissue development
Recovery and repair after training
Metabolic support as part of a broader plan
Strength and body-composition goals
IGF-1 LR3 is a modified form of the growth factor IGF-1, described by Australian scientists in 1992 as a research tool. Its published research is in cells and animals only.
IGF-1 LR3 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.
IGF-1 LR3 is a modified form of insulin-like growth factor 1, a protein the body makes naturally that helps drive growth and tissue repair. The LR3 changes let it stay active in the body considerably longer than the natural version, which is why it is studied for muscle growth and recovery. It is a research peptide, available at Cienega by prescription only after an individual evaluation.
IGF-1 LR3 is a modified form of insulin-like growth factor 1, distinct from other IGF-1 preparations, changed so that it binds less to the carrier proteins that normally regulate it and lasts longer in the body. There is essentially none. IGF-1 LR3 has not been studied in human clinical trials, and what is known comes from laboratory work, which your nurse practitioner will go over with you at your free consultation.
No. IGF-1 LR3 is not FDA-approved for any use. The modified form was originally developed as a laboratory reagent for cell culture work rather than as a medicine.
The World Anti-Doping Agency prohibits IGF-1 and its analogs, and use would cause a failed drug test in a tested sport. Your nurse practitioner reviews your health history, current medications and any 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.
