Why researchers choose us

Purity, speed, and value — in every vial.

We're a legal biotech research supplier. Every compound is synthesized in a controlled lab environment, third-party tested, and shipped fast so your work never waits.

≥99% purity, always

Every batch is HPLC- and mass-spec-verified by an independent lab. If it isn't above 99%, it doesn't ship — and the COA is available before you buy.

Next-day shipping

Orders in before the daily cutoff go out same-day. Next-day delivery is available to all US customers, with cold-chain packaging for sensitive compounds.

Transparent sourcing

USA-synthesized peptides with documented provenance and traceable batch records — no relabeled inventory, no mystery vials.

FAQ

Questions, answered.

Purity standards

What purity level do you guarantee?+

Every batch is tested above 99% purity by an independent third-party lab using HPLC and mass spectrometry. If a batch tests below 99%, it doesn't ship.

Can I see a COA before I buy?+

Yes. The current batch's Certificate of Analysis is linked on every product page — identity, purity, and endotoxin results are all in the document.

How do you verify identity, not just purity?+

Mass spec confirms molecular weight matches the target sequence; HPLC quantifies purity and flags impurities. Both results appear on the COA for each batch.

Where are your peptides synthesized?+

All compounds are synthesized in USA-based labs with documented provenance and traceable batch records. No mystery vials, no relabeled inventory.

Shipping & delivery

How fast will my order arrive?+

Orders placed before the daily 2 PM Central cutoff ship the same business day. Next-day shipping is available to all US customers at checkout.

Do you offer cold-chain shipping?+

Yes — temperature-sensitive compounds ship with insulated packaging and ice packs sized to your transit time.

Which carriers do you use?+

UPS, FedEx, and USPS Priority. Next-day delivery is via UPS or FedEx; standard tracked delivery typically arrives in 2–3 business days.

Do you ship to all 50 states?+

Yes. We ship research peptides to every US state with tracked delivery. International shipping is not offered.
