These peptide questions cover the words and decisions that can feel unfamiliar on a first read. We explain the research limits and access questions without asking you to arrive with a science background.

The first questions count
What is a peptide?
A peptide is a short chain of amino acids, the pieces that make proteins. Some peptides are part of ordinary body signalling. Others are made in a laboratory. The word describes a kind of molecule, not a guarantee of safety, approval or usefulness.
Are the five entries here approved medicines?
They do not share one status. BPC-157, Wolverine, and CJC-1295 with ipamorelin have no FDA-approved product. There is no current approved sermorelin product in the U.S. Tesamorelin has an approved product for a specific condition in adults with HIV. Compounded preparations are not FDA-approved.
What does “compounded” mean?
A pharmacy or another permitted compounder prepares a medicine for a particular need. It is different from an approved finished medicine. Compounded medicines are not FDA-approved, and the rules governing ingredients and products still apply. A prescription is not an exemption from every rule.
What is Promise Peptides?
Promise Peptides is a U.S. telehealth platform. Licensed U.S. providers review each request and decide whether prescribing is appropriate. Licensed U.S. compounding pharmacies prepare what is prescribed; the platform is not itself a pharmacy. Compounded medicines are not FDA-approved.
Is Perform part of that service?
Perform Peptide is an independent guide and is not Promise Peptides. Perform Peptide may earn money when readers become Promise patients. The invitation links take you to that separate service; this guide does not assess or prescribe for you.
Does opening a product page mean I qualify?
No. Promise Peptides serves U.S. patients, availability varies by state and treatment, and not everyone qualifies. A licensed provider makes the decision after reviewing the request. A visible listing does not establish the legal basis for compounding a particular substance.
Why do you keep mentioning rats?
Because the species is part of the result. A surgically injured rat tendon is a different question from a sore human tendon after practice. Animal and cell experiments can support more research without establishing a useful or safe treatment in people.
Does better growth-hormone signalling mean better sleep?
That conclusion does not follow from a hormone measurement. Normal growth-hormone release is connected to sleep, but changing the signal does not automatically improve the night. The sleep guide separates normal physiology from studies of particular substances.
Is Wolverine the same as TB-500?
No. Wolverine is the pairing of BPC-157 and TB-500. TB-500 is a fragment of a longer protein called thymosin beta-4; findings for that longer protein cannot simply be assigned to the fragment. No controlled human trial establishes a recovery benefit for the Wolverine blend.
Are the two CJC-1295 forms interchangeable?
No. DAC is a chemical attachment that extends time in the body by binding a blood protein. CJC-1295 with DAC and without it are different active ingredients. The limited human DAC studies do not establish the effects of a different form or of a blend with ipamorelin.
Does a withdrawn FDA nomination mean clearance?
No. On the FDA page current as of April 22, 2026, withdrawal means a request for evaluation was taken back. It does not grant FDA clearance, approval or permission to compound. Ipamorelin acetate appears in both the withdrawn table and Category 2 under the 503B interim policy for registered compounding facilities. Category 2 identifies significant safety concerns. The page gives no individual withdrawal dates.
What if I take part in tested sport?
The 2026 prohibited list names BPC-157, TB-500 and the growth-hormone-related compounds discussed here. Prohibition applies in and out of competition. A prescription does not automatically provide permission under sport rules. A clinical decision and any sport exemption process are separate matters.
