Know what you’re looking at.
Twelve of the most-searched names in peptide care, each explained the same way: what it is, where the research stands, its FDA status, and what a prescription route looks like.
How to read a library page
Study summaries identify the model used. Much peptide research is in cells and animals, and a result in rats is not a result in people.
Reading the evidence
Study models, populations and preparations differ. Findings for one do not establish outcomes for another.
All peptides
- Synthetic peptideBPC-157A synthetic 15-amino-acid peptide based on part of a protein found in human gastric juice.Read the guide
- Synthetic peptideTB-500A short synthetic fragment of thymosin beta-4, a protein found in most human cells.Read the guide
- Copper tripeptideGHK-CuA copper-binding tripeptide that occurs naturally in human plasma.Read the guide
- BlendKLOWA four-peptide blend: BPC-157, TB-500, GHK-Cu and KPV.Read the guide
- BlendGLOWA three-peptide blend: BPC-157, TB-500 and GHK-Cu.Read the guide
- Growth hormoneSermorelinA synthetic copy of the first 29 amino acids of growth-hormone-releasing hormone.Read the guide
- Growth hormoneCJC-1295 + IpamorelinTwo peptides that act on growth-hormone signals through different receptors, the cells’ signal receivers. Promise Peptides lists the combination; a licensed provider decides. FDA keeps ipamorelin acetate in Category 2 because of significant safety risks. That status applies under section 503B, the rules for registered outsourcing facilities that compound drugs.Read the guide
- Mitochondrial peptideMOTS-cA 16-amino-acid peptide encoded in mitochondrial DNA.Read the guide
- CoenzymeNAD+Nicotinamide adenine dinucleotide, a coenzyme every living cell uses in energy metabolism.Read the guide
- MetabolicSemaglutideA GLP-1 receptor agonist. The compounded form is not FDA-approved; approved versions exist.Read the guide
- MetabolicTirzepatideA dual GIP and GLP-1 receptor agonist. The compounded form is not FDA-approved; approved versions exist.Read the guide
- Melanocortin agonistPT-141Bremelanotide, a synthetic peptide that acts on melanocortin receptors.Read the guide
Looking by goal instead?
Promise Peptides prescribes these peptides now through licensed U.S. providers. Every request is reviewed; the provider decides and not everyone qualifies. Goal names group treatments and do not establish a benefit.

For the listed CJC-1295 + Ipamorelin combination, a licensed provider decides. FDA lists ipamorelin acetate in Category 2 under 503B because of significant safety risks; its nomination also appears in FDA’s withdrawn table.
