HPLC purity, every lot
No compound leaves the facility below 99% purity by high-performance liquid chromatography — retested independently, not just at synthesis.
Made in the USA
Synthesized, lyophilized, and verified in California.
Most private-label suppliers import finished compound and relabel it domestically. PureTide synthesizes every research peptide in its own Orange County facility, re-verifies it independently, and puts the lot number on your label — so your brand rests on chemistry, not luck.
The PureTide standard
99 percent is where we start, not where we stop.
≥99%
HPLC purity · verified per lot
Mass-spec identity
Molecular weight confirmed by mass spectrometry against the published structure, so the sequence on the label is the sequence in the vial.
COA with every shipment
A certificate of analysis accompanies each lot, tied to the lot number printed on your label. Your customers can verify what you sell.
American manufacture
Synthesized, lyophilized, and finished in Orange County, California — no overseas relabeling, no customs roulette, no six-week lead times.
Domestic vs. imported
Not all “made for your brand” is made the same.
| PureTide | Typical overseas relabeler | |
|---|---|---|
| Synthesis | Domestic — synthesized and lyophilized in Orange County, CA | Imported material, relabeled after the fact |
| Purity verification | ≥99% HPLC, independently re-verified per lot | Purity unverified after import |
| Certificate of analysis | COA issued per lot, tied to the lot number on your label | COA on request, or none at all |
| Lead time | 48-hour US dispatch, no customs | 4–6 week import lead times |
