The sources behind the catalog
Every compound is sourced from independent vendors. Here's what each one offers — batch & lot traceability, US-warehouse shipping, independent lab testing, lot-specific COAs, purity guarantees, and refund/reship policies. Filter by what matters to you.
Nuvexa Peptide Institute
US warehouse — batch + lot numbers on every order.
A US (California) warehouse shipping domestically in about 2–5 days. Every order carries batch and lot numbers, and the catalog is independently lab-tested with an extensive library of published COAs. Content and purity are guaranteed.
Nuvexa Peptide Institute (China)
China warehouse — same lab-tested catalog, direct-from-source pricing.
The Nuvexa China warehouse: the same independently lab-tested catalog, shipped internationally, with batch and lot numbers and published COAs. Content and purity guaranteed. Live stock and pricing are pulled directly from the source.
Peptiva Research Facility
US warehouse for the most in-demand compounds.
Ships the most in-demand GLP-1s and Selank from a US warehouse in about 2–6 days. Every batch is independently tested by Janoshik for both purity and fill volume, and Peptiva reships or refunds if a result comes back under spec — or if a parcel is held in customs.
Orchid Cloud
A broad-catalog source covering most of our compounds at competitive prices. Independently lab-tested with an extensive COA library, and backed by a refund-or-reship guarantee if a test comes back under spec or a parcel is held in customs.
Pepturion
A wide-ranging source with a strong purity track record, including harder-to-find compounds. Independently lab-tested with an extensive COA library, and backed by a refund-or-reship guarantee.

What the badges mean
- US Warehouse
- Ships from a US warehouse for fast domestic delivery — the estimated time is shown on the badge.
- Batch Numbers
- Every kit carries a traceable batch number — not just a cap colour — so it can be matched back to a test result.
- Independent Lab Tested
- Batches are sent to an outside analytical lab (e.g. Janoshik) rather than tested in-house — the lab is shown on the badge.
- Extensive COA Library
- A deep, ongoing testing history — hundreds of certificates of analysis built up over time, not a one-off test.
- Fill-Volume Verified
- Fill volume is measured alongside purity, so you receive full kits rather than short-fills.
- Purity Guarantee
- States a minimum purity the vendor stands behind, with recourse if a test comes back lower (floor shown on the badge).
- Refund / Reship
- Refunds or reships if an independent test fails or a parcel is seized by customs.
