Why SUNSET LABS
Confirmed by HPLC and mass spec
Every specification stated, every batch held to an independent analysis — so you always know exactly what you are working with.
High purity
Compounds are supplied at >99% purity by HPLC. Purity shown is the supplied specification; the batch Certificate of Analysis is the source of record — see exactly where that stands.
Single compounds
One compound per vial — no blends, no fillers. You know exactly what you are working with and at what quantity.
Batch COA
Our standard is for every batch to ship with an independent Certificate of Analysis confirming identity and purity. See exactly where that stands.
Proper handling
Lyophilized, stored cold, and shipped with clear reconstitution and storage guidance for the lab.
See exactly how we source, specify, and test — read our standards.

Quality & testing
High purity, documented per batch
Every compound is a single, identified molecule — purity by HPLC, identity by mass spec. Our standard is for that analysis to ship with each batch on an independent COA, so you never have to take our word for it.
- Peptides supplied at >99% (HPLC) — the analytical profile lives on the batch COA.
- Our standard: an independent Certificate of Analysis per batch (see exactly where it stands).
- Lyophilized, cold-stored, and shipped discreetly with clear handling guidance.
Why we exist
“Sourcing research peptides shouldn’t mean guessing. So we built the opposite: one identified compound per vial, every specification stated, and the standard of an independent batch analysis — identity by mass spec, purity by HPLC. Rigorous on purpose, documented on principle.”
