The full range
Every question, answered before you order
Four families. Open the one that is holding you back.
Four reports from Janoshik Analytical (an independent laboratory) are published: Retatrutide 10, 20 and 30 mg (99.3–99.8%) and GHK-Cu (99.6%), each verifiable at the lab. Every product page says whether the report for the other peptides is still pending.
The lyophilized peptide, sealed, with the compound and quantity on the label; the Janoshik report of each size is published once it comes back. Stored at −20 °C, sealed. Diluent water (bacteriostatic) ships free with every peptide.
No. Research use only. Not for human or veterinary use. Products are sold to laboratories and qualified researchers, and every buyer confirms being 21 or older and purchasing for laboratory research.
Check it yourself: every Janoshik Analytical report carries a key you can verify at the laboratory, and 156 of our last 162 tracked parcels were delivered. Every proof, on one page

Check three things: a registered company, independent lab reports you can verify (Janoshik keys), and real delivery data. OXpeptides publishes all three on /is-oxpeptides-legit.
About OXpeptides
Who we are
OXpeptides supplies lyophilized research peptides in sealed glass vials, and one laboratory diluent, to researchers and laboratories.
How we work
Our reports come from Janoshik Analytical, one per size: HPLC purity and mass-spectrometry identity. Each report is published on the product page with its date as soon as the laboratory returns it; a product whose report is not back says so, in those words, rather than borrowing figures from elsewhere. Every vial is crimp-sealed and carries the compound name and the net quantity in milligrams; each report is published with its task number and verification key. Orders ship from the warehouse that serves the delivery address, tracked.
Who we sell to
Researchers and laboratories. Three things we do not do: we publish no quantities, no routes and no schedules anywhere on this site, and support declines those questions; we publish no certificate we do not hold; and we publish no customer review that does not come from a verified order.
The full entity record, the testing method step by step and what the company does not do are on the About page.
