Purity is where most vendors stop.
Almost any vendor can confirm a peptide is 99% pure. Far fewer screen for the heavy metals, endotoxins, and microbes a purity test never catches — and almost none let you call and verify your exact lot. We do all three.

Quality you can verify, not just trust.
Every lot is independently tested by accredited U.S. laboratories. We do not ask you to take our word for it — we ship the analytical record with the vial.
Verified Potency
HPLC AnalysisEach lot is HPLC-tested so the analytical readout matches the labeled mass — down to the microgram.
Why it matters: Verifiable potency for reproducible bench work. No surprises mid-experiment.
For anything past the bench, talk to a licensed clinician.
We partner with one directly. Pure Primary Wellness & Aesthetics is a licensed medical practice in Monroe, North Carolina — a real clinician, real patients, a street address you can walk into.
Their door is open if you’d like to talk to someone licensed.
