Promise does not offer care outside the U.S. NXT LVL / FIELD NOTES Evidence before expectations ## Where our facts come from. - [FDA review of CJC-1295](https://www.fda.gov/media/183819/download) The different CJC-1295 forms, the human studies and the limits of the evidence. - [FDA review of ipamorelin](https://www.fda.gov/media/182088/download) What ipamorelin is, which human studies exist and which safety questions remain. - [FDA peptide ingredient safety listings](https://www.fda.gov/drugs/human-drug-compounding/certain-bulk-drug-substances-use-compounding-may-present-significant-safety-risks) The withdrawn nominations and the separate safety listing for ipamorelin acetate. - [FDA records for sermorelin](https://api.fda.gov/drug/drugsfda.json?search=openfda.generic_name:%22sermorelin%22+OR+products.active_ingredients.name:%22SERMORELIN%22) The earlier approved products and their discontinued status. The linked record is technical. - [Current approved tesamorelin drug label](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=839334d3-8c1d-4c26-9036-2ab524a6ea75) The specific approved use, limits of use, safety warnings and provider checks. ## Match the source to the claim. A small human study can describe a hormone response without establishing a result for training or recovery. A drug label applies to its specific finished product and indication, meaning its approved use. A compounding listing describes ingredient rules; it is not an approval of a medicine. FDA's ingredient safety page used here is marked current as of April 22, 2026. It does not publish individual dates for withdrawn nominations. The guide does not assign dates that the record cannot support. ## What these links cannot answer. They cannot establish personal eligibility or make a combination equivalent to an approved product. The side-by-side notes and beginner questions give the plain-language context. Promise lists these options for provider review. A licensed U.S. provider decides whether to prescribe. The listing does not change FDA status or the rules for the exact ingredient. [Read the side-by-side notes](/compare/) [Read the beginner questions](/faq/) ## Put the next step in licensed hands.
