Single compounds. Documented purity.
Single-compound research peptides — our standard is identity by mass spec, purity by HPLC, and an independent Certificate of Analysis per batch. For laboratory research use only. We started SUNSET LABS because sourcing research peptides had become harder to trust than it should be — and we thought it could be calmer, plainer, and more honest.
The standard we hold ourselves to
Why we exist, in plain terms — and what we won’t cut.
SUNSET LABS started with a simple frustration: too many suppliers ask you to take their word for it. Vague specs, no documentation, no way to know what’s actually in the vial. We wanted the opposite — products you can verify, with the analytical data in the open.
So we kept it narrow. Single, identified compounds at high purity, reference specifications stated plainly, and the standard of an independent batch Certificate of Analysis behind every vial. The catalogue is organised the way research is — metabolic, cognitive, recovery — plus the ancillaries that go with them.
We put the data in the open, not the adjectives. If a figure isn’t verified yet, we say so plainly and show you where the proof will live. Everything here is supplied for laboratory and research use only — that’s the standard we’re holding ourselves to as we grow.
How we want to earn your trust
- Single, identified compounds at high purity — no blends, no fillers.
- Reference specifications stated plainly, with the batch COA as the source of record.
- Neutral, research-only language: what a compound is, never how to use it.
- Transparency about testing and certifications, including what is still pending.
