cGMP-aligned manufacturing, compliance & testing
cGMP · 21 CFR 211
ISO/IEC 17025 · ILAC MRA
Manufacturing follows cGMP-aligned protocols adapted from 21 CFR Part 211 — documented batch records, controlled-environment monitoring, and lot-by-lot release testing.
Current COA-backed lots are documented around four checkpoints: HPLC purity, bacterial endotoxin, sterility, and heavy metals, with identity and lot details matched to the published certificate.

Questions you may have
Every current COA-backed lot is documented for HPLC purity, bacterial endotoxin, sterility, and heavy metals, with identity and lot details listed on the Certificate of Analysis. The matching COA is posted on each product page and in the lab reports library.
Keep lyophilized (freeze-dried) vials in a cool, dark place away from direct light. For longer holds, refrigerate or freeze them. Once reconstituted, store the vial refrigerated and use it within the window noted on the product's COA.
Mytide is US sourced and fulfilled stateside, current COA-backed lots are quadruple-tested for purity, endotoxin, sterility, and heavy metals, and stocked orders dispatch fast. No overseas transit, no customs delays, and no guessing about documentation.
Stocked orders dispatch within 24 hours. Lyophilized peptides stay stable at room temperature across the short transit window, so cold-chain shipping is not required for standard delivery.
Stored properly, lyophilized peptides stay stable for extended periods, commonly 18 to 24 months. Temperature and light exposure are the main factors, so check each product's COA for lot-specific guidance.
A COA lists compound identity, measured purity, endotoxin status, sterility status, and lot-level certificate details. Our COA guide walks through each section line by line. Read the COA guide.
