Research peptides, with the paperwork attached.
RetaPure is a specialist supplier of research peptides and cofactors. Every lot is tested by an independent laboratory, and each Certificate of Analysis is documented per lot and published in the archive as lots are released - no login, no email gate. That is the whole pitch.
The research-peptide market has a documentation problem.
Most suppliers claim purity, then bury the evidence. Certificates are gated behind contact forms, reissued internally, or simply not provided. Customers end up buying on brand trust - which is the exact opposite of how research reagents should work.
Verification isn't marketing. It's the bare minimum. We document every lot's Certificate of Analysis and publish it in the verification archive as lots are released, without a login or an email gate.
Everything that can be verified, is.
Three things are public. No login, no email gate, no "contact us for documentation."
Certificates of analysis
Each lot's Certificate of Analysis is documented and added to the verification archive as lots are released. Third-party results, unedited. Updated if a lot is re-tested.
View archive →Testing methodology
Every lot is analyzed by HPLC for purity and mass spectrometry for identity. Methods are the same across lots, so comparisons are meaningful.
What we test for →Lot traceability
Every vial includes a QR code on the label that links directly to that lot's Certificate of Analysis.
How lot lookup works →How a lot moves through the system.
Every lot follows the same path. No shortcuts, no parallel paths for different customers. This is operations, not marketing.
Synthesis & receipt
Lot arrives from a qualified synthesis partner with manufacturer documentation.
Third-party QC
Sample is pulled and sent to an independent laboratory. HPLC and mass spectrometry.
CoA verified
Results reviewed. The lot either passes and moves forward, or is rejected. No partial passes.
Compound-specific storage
Stored according to compound-specific handling requirements until fulfillment.
Pick & pack
Orders pick from the current lot. Vial labels include the QR pointer to that lot's CoA.
Ship & archive
Same-business-day ship by 2 PM CT*. CoA stays in the public archive, permanently.
What we refuse to do.
Most supplier sites are defined by what they claim. We are also defined by what we will not do. These are not oversights; they are choices.
No medical, therapeutic, or performance claims.
Not in marketing copy, not on product pages, not in customer support. If you see our products promoted with health claims by a third party, it is not us.
No human-use framing.
No dosing guides, no protocols, no "how to use" content. Research Use Only isn't a disclaimer at the bottom of the page - it's the entire positioning.
No "research grade" claims without the document.
If a product is described as tested, the test is attached. No adjectives doing work that a certificate should be doing.
No international shipping. No drop-shipping. No resellers.
US domestic only. We hold our own inventory, store it ourselves, and ship from a single facility. Customs risk, chain-of-custody gaps, and margin-stacking resellers aren't worth the operational cost.
No cards, no crypto, no cash.
Bank-to-bank ACH only - same as how research institutions and lab suppliers invoice each other. Cleaner records, lower processing overhead, and no card data stored anywhere.
No partial QC and no "hold for priority customers."
Every lot follows the same QC path before it's available to anyone. There's no priority tier that skips verification, and there's no "internal" stock not listed in the public archive.
What to expect, in plain numbers.
No hedging language. These are the commitments.
Same-business-day ship on orders placed by cutoff, pending ACH authorization. Mon-Fri, excluding federal holidays.
HPLC purity and mass spectrometry identity, by a third-party US laboratory. Unedited.
Each Certificate of Analysis is added to the verification archive when its lot is released and remains available afterward.
Tracked from first scan. US domestic only. Discreet, unbranded packaging.
