A plain-language starting point for research peptides — what they are, how we test for quality, and how reconstitution works. All of it educational reference for laboratory research, not medical advice.
What are peptides?
Peptides are short chains of amino acids — the same building blocks that make up proteins, just far smaller. Where a protein might be hundreds of amino acids long, a peptide is typically only a handful. In the body they act as signaling molecules: they bind to specific receptors and pass along instructions, nudging natural processes like tissue repair, metabolism, or hormone release rather than forcing a brand-new one.
Because each sequence is so specific, different peptides are studied for very different purposes — recovery and repair, metabolic and weight research, cognitive and stress research, and more. That specificity is exactly why researchers care which compound, which sequence, and which batch they're working with.
How we ensure quality
In a market where claims are easy to make and hard to check, we lead with documentation. Every batch is sent to an independent third-party lab — Janoshik Analytical or Vanguard Laboratory — and analysed by HPLC for purity and by mass spectrometry to confirm the compound's mass. The result is a Certificate of Analysis tied to a specific lot number, not a blanket marketing line.
Our intent across the catalogue is 99%+ purity, and the figure you see is always the one measured for that batch. We post those certificates — batch number and all — so you can read the actual numbers before you inquire, and Janoshik reports can be verified independently at their source.

Most research peptides ship lyophilized — freeze-dried to a dry powder for stability. Before use they're reconstituted: dissolved in bacteriostatic water, a sterile water with a small amount of preservative that keeps the solution stable for repeated draws. How much water you add sets the concentration, which in turn sets the volume of each unit you measure out.
On a U-100 insulin syringe, “units” are hundredths of a millilitre — 100 units to 1 mL — so a little arithmetic converts a target amount into a mark on the syringe. A common approach in the literature is to start low and adjust gradually rather than jumping to a high amount. Our dosage guide lists a suggested fill volume and the resulting per-unit maths for each compound.

If you're just getting oriented, it's usually easier to start with well-characterised, foundational compounds — the ones with the most published research and the clearest handling notes — before moving to anything niche or complex. Read the Certificate of Analysis for the batch, understand the reconstitution maths, and keep good records of exactly what you're working with.
Above all, keep the framing straight: everything here is supplied for laboratory and research use only. The material on this site is educational reference to help you evaluate compounds and handle them properly — it is not a protocol, a prescription, or a recommendation for any use in people or animals.
