Frequently asked questions
Handling, storage, testing and trade. These answers stay quality-focused and never give a dose, a protocol or a use in the body. If you need to know how to use a material in or on a living system, we cannot and will not tell you: these products are laboratory reagents, and that is outside what we supply.
Every batch is characterised by an independent third-party laboratory and shipped with a Certificate of Analysis (CoA). Identity is confirmed by mass spectrometry, purity by HPLC with the chromatogram, plus a safety panel including heavy metals (ICP-MS) and bacterial endotoxin (LAL). The salt form is stated, because the counterion changes the peptide content per milligram. See how we test.
It links to that specific batch’s Certificate of Analysis: named lab, lot number, and every test dimension. No manual cross-referencing. Every published certificate also lives in our searchable, per-batch library at lab results.
Each certificate carries a verification key issued by the testing laboratory. You can take that key to the lab’s own website and confirm the result directly at source, independently of anything we host. A certificate belongs to your vial only when the product identity, the lot number and the appearance all match what you received.
Look for identity confirmed by observed mass against expected mass, purity by HPLC with a chromatogram rather than just a number, the salt form stated, and a safety panel. For blends, each component should be resolved separately. Our full guide to reading a CoA walks through each figure and the common traps.
Most peptides are supplied as a salt, paired with a counterion such as acetate, trifluoroacetate (TFA) or arginate rather than as the free base. That counterion has weight, so it accounts for part of the powder in the vial. Two vials both labelled, for example, 10 mg can therefore contain slightly different amounts of the actual peptide if their salt forms differ, because part of the mass is counterion, water and other residue rather than peptide. This is why the CoA states both the salt form and the net peptide content: purity tells you how clean the peptide fraction is, and content tells you how much of the powder is peptide at all. We state the salt form so the figure on the label means something precise.
Bacteriostatic water is water containing a small amount of a preservative (typically benzyl alcohol) that inhibits the growth of bacteria, which is why it is often used as a laboratory solvent for reconstituting lyophilised material for study over a working period. In our context it is simply a reagent: we describe it only as a laboratory solvent, and we give no dose, no protocol and no use in or on the body.
Reconstitution is dissolving a lyophilised (freeze-dried) powder into a liquid so it can be handled in the lab. It is a solution-preparation step, not a dose: a milligram to millilitre to milligram-per-millilitre calculation only. We do not advise on how any solution should be used, because these products are for laboratory research only.
Keep lyophilised vials cold, dry and protected from light; the freeze-dried powder is the stable, long-shelf-life form. Once reconstituted, peptides are far less stable and cold-chain dependent. NAD+ is more moisture and heat sensitive, so treat it as shorter-lived. These are general laboratory-handling notes, not use guidance.
GHK-Cu should be blue; a colourless, green or brown solution suggests the copper is not correctly complexed. A white or off-white cake is normal for most peptides. Cloudiness after reconstitution is a red flag. These are first-line indicators only; the definitive record is the CoA, and its stated appearance should match the vial in your hand.
Glow contains GHK-Cu, BPC-157 and TB-500. KLOW (KGlow) is Glow plus KPV. CJC-1295 (no DAC) plus ipamorelin is a two-peptide blend of those named actives. We publish which peptides and what milligram split make up each vial, and lock the ratio so a blend name means one defined thing across batches. We do not publish any use or protocol.
Each named component is resolved separately on the certificate, so the identity and content of every peptide in the vial can be confirmed rather than assumed. A blend CoA that cannot separate its components is incomplete.
Axyn supplies the research market on a business-to-business basis, for qualified professionals conducting in-vitro laboratory research who are aged 18 or over. By ordering you confirm you meet those conditions and that the materials are for lawful research use only. See our research use policy.
We accept card payment and Open Banking (pay-by-bank) at checkout [payment methods to be confirmed]. We do not take payment by informal or off-platform means; checkout is handled through our standard secure process.
Because these are sensitive research materials, returns are limited to unopened, undamaged items within the stated window, and opened vials cannot be accepted once the tamper-evident seal is broken. For the full conditions and how to start a return, see our returns policy.
