What is a peptide?

A peptide is a short chain of tiny pieces called amino acids.

That is the whole definition people need on a first read. Amino acids are the small molecules that link up to make proteins. The National Human Genome Research Institute says a peptide is that short chain, usually 2 to 50 of those pieces, hooked together by a bond. A longer chain is a different word. Their page is Peptide. The version with the numbers, the bond, and the GLP-1 hormone is What scientists mean by peptide. You can skip that one.

People use "peptide" for a lot of products that are not the same thing. A scoop of collagen powder and a face cream are the two that ordinary health pages mean. Neither one is a research vial. That split is collagen powder and a face cream.

• Insulin is a peptide. It is an old prescription drug.
• The ingredient in Ozempic, Wegovy, and Rybelsus is semaglutide. That is a peptide made as a medicine. Sema on this shop is not those pens or that pill.
• Tirz is tirzepatide. Reta is retatrutide. The short names and the prices are on tirz, reta, and sema.
• BPC is BPC-157. Wolverine, GLOW, and KLOW are nicknames for blends in one vial. The label note is Wolverine, GLOW, and KLOW.

A research vial on this shop is a small sealed bottle. The peptide inside is a dry powder. The label has a name and a milligram number. You can buy one. Every research vial is at least 99% pure, and the fill is within 10% of the label. A 10mg label means 9mg to 11mg. That math is spelled out in what 99% and 10% mean.

"Gray market" is the ordinary name for buying a peptide outside a pharmacy. The label on that kind of bottle often says research use only. It is not a permission slip, and it is not the same product as a brand pen or a compounded prescription. The longer quotes are on Hollywood and San Francisco and on compounded and research.

If you only wanted the shop in one screen, new here is the short version. The catalog is peptides. One bottle to look at is try one vial.
