A short chain of amino acids — the same building blocks that make up proteins, just far fewer of them. Your body already makes thousands of them, and uses them as messengers: insulin is a peptide, so is the GLP-1 your gut releases after a meal. A therapeutic peptide is a copy of one of those messages, or a close analogue of it, made in a lab. That is the whole idea. You are not introducing something foreign so much as re-sending a signal your body already understands.

No. Our products are sold as research compounds, which is why every vial is labelled for research use and why nothing on this site is presented as medical treatment. Deciding whether something is appropriate for you sits with you and whoever advises you.

Start with the goal, not the compound. Pick the collection that matches what you are actually trying to change, read the primer at the top of it, and look at what we have marked as a starting point rather than the strongest option. Then order the essentials in the same order — bacteriostatic water and a reconstitution kit — because a vial of powder is not usable without them.

Peptides ship as a freeze-dried powder because they are far more stable that way. Reconstitution is adding bacteriostatic water to turn that powder into a measurable liquid. It matters because the ratio you choose determines what every subsequent dose actually contains — get the ratio wrong and every dose after it is wrong too. Our reconstitution kit includes a chart so you are not doing the arithmetic yourself.

It depends on the compound. GLP-1 compounds change appetite within a week or two. Collagen-signalling peptides need six to ten weeks because new collagen has to physically be built. Recovery compounds usually show up around week three. Every product page on this site has its own timeline for exactly this reason.
