Peptix USA Review: Our Verdict
- A working cart example:
pepadded a free BPC-157 10 mg vial to a two-vial cart on October 19. The $2.50 two-vial bundle discount remained in the total. - Reports differ by product: the BPC-157 report we opened is from Freedom Diagnostics; the latest retatrutide report is from ILS Laboratories. The latter includes a wider panel.
- Small catalog: the store displayed seven products on October 19, including bacteriostatic water; NAD+ was marked as coming soon.
- US only: the store says it ships to all 50 states, with free shipment protection and free shipping at $150+.
- Check the details: the free item and bundle behavior were tested for one product only. Review the certificate for the lot you receive and confirm your own cart total.

Estimated Savings with pep
On October 19, the store displayed these starting single-vial prices. Actual eligible items, strengths, bundle pricing and the free item can change; the only cart total we tested is BPC-157 below.
| Product | Starting price for one | Cart result with pep |
|---|---|---|
| BPC-157 10 mg | $40.00 | Two paid plus one free: $77.50 before shipping, including the two-vial bundle discount |

| Tirzepatide | From $58.00 | Not tested |
| Tesamorelin | From $62.00 | Not tested |

The BPC-157 cart showed a $118.75 subtotal for the three vials, a $2.50 bulk discount, and $38.75 in deal savings. We did not test mixed products, other quantities, or the referral link’s automatic application of the offer.
Peptix USA Lab Reports and Purity
We opened two certificates linked from product pages on October 19, 2026. These results apply only to the submitted samples, not every vial sold.
| Product and lot | Lab and date | Purity | Identity and net content | Other tests |
|---|---|---|---|---|
| BPC-157 10 mg, D87432 | Freedom Diagnostics; reported April 23, 2026 | 99.66% by HPLC-UV | Confirmed by LC-MS; 11.43 mg | The report does not list endotoxin, sterility or heavy-metal testing |
| Retatrutide 10 mg, D687432 | ILS Laboratories; analyzed October 16, 2026 | 99.90% by HPLC | Confirmed by HPLC retention-time comparison; 10.65 mg | Heavy metals not detected within stated limits; PCR sterility no growth; endotoxin reported at not more than 0.05 EU/mL; fentanyl not detected |
Peptix’s homepage FAQ names Freedom Diagnostics, while its about page names multiple labs and the latest retatrutide certificate is from ILS. The ILS report caps purity at 99.9% to reflect its detection limit and says sample identification was supplied by the client. Ask for the certificate matching your lot and verify it with its issuing lab. Our COA guide explains what to look for.
