Peptides & Products
What we sell, how it is made, and how it is verified.
What form do the compounds arrive in?
Every vial ships as lyophilized powder, sealed under vacuum with a crimped aluminium cap. Nothing is pre-reconstituted.
Is Every Lot Really Tested?
Yes. Identity is confirmed by mass spec and purity by reverse-phase HPLC, and a retained sample goes to a second, unaffiliated lab. Both certificates are published against the lot number before the product page goes live.
How Do I Find the Certificate for My Vial?
Enter the lot number printed on the vial label into the COA lookup. The same certificate is archived permanently in your account after purchase.
What purity should I expect?
Listings state the measured purity for the lot in stock, typically 98% or higher. The figure on the page always comes from the certificate, not from a supplier specification.
What do the size variants mean?
The variant is the mass of peptide in the vial — for example 5mg or 10mg. Concentration depends on the volume of solvent you add during reconstitution.
How Should Material Be Stored?
Lyophilized powder is shelf-stable and needs no cold chain in transit. For long-term storage keep it at −20°C, sealed and away from light. Once reconstituted, refrigerate and use within the window appropriate to the compound.
