99% Pure Research
Peptides, Independently
Verified. — Pure Helix research peptides for in-vitro laboratory study. Every released peptide lot meets our minimum 99% chromatographic purity standard with independent analysis for identity and quantity, published on the lot-specific certificate of analysis.
Browse compounds by research pathway.
Each pathway is mapped to a focused area of in‑vitro research — from metabolic signaling to tissue repair and neural models.
Peptides, blends, hormone analogs, and cofactors — grouped by pathway. Purity, identity, and net contents are reported per lot.

US-based
Independent assays
Batches are submitted to an independent third-party United States laboratory for identity, purity, and net-quantity testing. Results are published on a lot-specific certificate of analysis — see how we test or look up a lot on the COA lookup.
The catalog is organized by research pathway — metabolic, cellular and mitochondrial, tissue signaling, neuroscience, neuroendocrine, and the growth hormone axis — and includes compounds such as semaglutide, tirzepatide, retatrutide, BPC-157, TB-500, GHK-Cu, and ipamorelin, plus reconstitution supplies. Browse the full research compound catalog.
Orders ship from the United States. Lyophilized material is shipped at ambient temperature and should be stored per the storage note on each product page; reconstituted material is kept refrigerated and protected from light. Handling guidance is documented under lab standards.
Purchasing is limited to qualified researchers and laboratory personnel who accept the research-use agreement. Materials are not for human or veterinary use, and no dosing, therapeutic, or clinical guidance is provided.
