Retatrutide, BPC-157 & Epitalon: A Look at Our Current Research Peptides for Sale

We currently stock six research peptide kits, each backed by a current, independently-issued lab report. Below is a factual overview of what’s in the catalog right now — chemical identity, not marketing claims — alongside a link to the verified batch data for each one.

Retatrutide Research Kits (R10 / R20 / R30)

Retatrutide (CAS 2381089-83-2, molecular formula C221H342N46O68, molecular weight approximately 4731.33) is a triple agonist peptide studied in research literature for activity at GLP-1, GIP, and glucagon receptors. We currently offer it in three fill sizes:

• Retatrutide 10mg Research Kit (R10) — current batch verified at 99.46% purity (HPLC-UV) with LC-MS identity confirmation, tested by Freedom Diagnostics Testing.
• Retatrutide 20mg Research Kit (R20) — current batch verified at 99.83% purity, also tested by Freedom Diagnostics Testing.
• Retatrutide 30mg Research Kit (R30) — current batch verified at 99.693% purity by Janoshik Analytical, with identity confirmed against a blind panel that included Semaglutide and Tirzepatide alongside Retatrutide.

BPC-157 Research Kits (BPC10 / BB10)

BPC-157 (CAS 137525-51-0, molecular formula C62H98N16O22, molecular weight approximately 1419.54) is a synthetic 15-amino-acid peptide fragment (sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) that has been studied in preclinical research models. We offer it standalone and as part of a blend:

• BPC-157 10mg Research Kit (BPC10) — current batch verified at 99.90% purity, tested by Freedom Diagnostics Testing.
• BPC-157 / Thymosin Beta-4 Blend 10mg Research Kit (BB10) — a combination kit with both peptides confirmed and quantified separately: current batch shows a combined purity of 99.32%, with BPC-157 and Thymosin Beta-4 content individually verified via LC-MS.

Epitalon Research Kit (EPI10)

Epitalon (CAS 307297-39-8, molecular formula C14H22N4O9, molecular weight approximately 390.35) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly, studied in aging-related research literature. Our Epitalon 10mg Research Kit (EPI10) is currently verified at 99.85% purity, tested by Freedom Diagnostics Testing.

Every Batch Is Independently Verified — Check It Yourself

None of the figures above are marketing estimates. Each one comes directly from the current batch’s lab report, and we link to the primary source — not our own summary of it — for every product we sell. The complete, current list lives on our Certificates of Analysis page, where each entry links to either a Janoshik Analytical verification page or a Freedom Diagnostics Testing PDF, keyed to the accession or task number printed on the product itself.

If you’re new to reading these reports, our article on why third-party COA testing matters walks through what each section of a report actually means. And if you’re comparing us against other options, our guides on what to look for in a research peptides supplier and evaluating research peptides for sale cover the same checks we hold ourselves to.
