Not Peptides

This varies by peptide. As a general guideline, most reconstituted peptides remain stable for approximately 14–28 days when kept continuously refrigerated, but some are stable for shorter or longer periods. The product page for each compound lists the specific post-reconstitution shelf life. Mark the date you mixed the vial, and discard any remaining solution past that window. If the solution turns cloudy, discoloured, or develops visible particles before the deadline, do not use it. An 8 mm (5/16″) 30-gauge needle is the standard recommendation for subcutaneous peptide injection in average-adult body compositions. If you have very little subcutaneous fat at your chosen injection site, you may prefer to pinch the skin more firmly to ensure the tip stays in the fat layer rather than reaching muscle. If you consistently find 8 mm uncomfortable, let us know by text or email — we are looking into stocking a shorter length (e.g., 4 mm / ⅝″) in the future. Acetic acid water is a sterile dilution solution that contains a small concentration of acetic acid. Some peptides — including Epitalon, Thymosin α-1, Kisspeptin-10, Tesamorelin, and AOD9604 — are more stable in a mildly acidic environment and will not dissolve properly in plain bacteriostatic water. If a product page says ‘Requires Acetic Acid Water,’ use that solution rather than BAC water. We stock both, so you can add the correct one to your cart.
