Quick take. A named operator, a named lab with checkable search codes and a 30-day refund window, offset by hidden pricing, a removed Trustpilot profile and a middling Finnrick record.

Quick take

Simple Peptide, at simplepeptide.com (singular), is a Delray Beach, Florida business run by Melex Technologies Inc. It describes itself as family-run, carries a ‘Since 2019’ badge and says it fully launched in 2023. The catalog is broader than most: lyophilized vials plus dissolvable ‘BioStrips’, oral peptides and a skincare line, including GLP-class listings. Pricing is visible only after sign-in, so no BPC-157 price could be recorded.

Who this supplier suits

This suits buyers who want a named legal operator with a street address and a toll-free line, a named lab whose search codes they can check, and a real 30-day refund window. It also suits buyers who need the strip or oral formats, which few peers carry.

It does not suit buyers who need to compare prices before registering, buyers outside the US, or buyers who want endotoxin and sterility data on older lots.

Testing in plain English

The lab is Freedom Diagnostics Testing in Franklin, TN. The supplier reports LC-MS for identity and HPLC-UV for purity, and says each certificate carries a search code that can be verified on the lab’s site. Certificates are per lot. The finished-lot standard is 99% purity or better where the molecule supports it, with exceptions documented on the lot COA.

Two caveats. Sterility, endotoxin and net-peptide-content results appear only on certificates issued in May 2026 or later, so older lots lack them. And the COA page is a lot-number search tied to the account page, so whether you can open a certificate without an account is unclear. The supplier claims no GMP, ISO or cGMP certification, and the lab makes no ISO 17025 claim on the vendor page.

Finnrick, an independent testing aggregator, reports 28 passes and 19 fails across 47 tests, latest Oct 8, 2026, a 63% rating, with BPC-157 at 48% and CJC-1295 at 25%. Those are Finnrick’s results on its own samples.

Prices and shipping

No prices are public. Shipping is US-only. Orders placed before 2:00 PM ET, Monday to Friday, ship the same business day by 2nd Day Air (UPS or FedEx), with USPS used for PO boxes. No free-shipping threshold is stated.

Service, returns and payments

Payments are card and bank. Contact is support@simplepeptide.com, 1-877-711-0702 and the Delray Beach address.

The refund policy is clear: 30 days on unopened, unused products in original condition, opened products case by case, customer pays trackable return shipping, refund 7 to 10 business days after inspection. The company also states it is not a 503A compounding pharmacy or a 503B outsourcing facility.

The Trustpilot profile for simplepeptide.com has been removed for going against Trustpilot’s guidelines. A separate Finnish-language Trustpilot page exists under the misspelled domain simplepeptides.com, which is not this supplier’s address. No FDA warning letter was found.

Final word

Simple Peptide scores on company transparency, a named lab with verifiable search codes and a refund window that most suppliers in this group do not offer. It loses points on hidden pricing, uncertain public access to certificates, the removed Trustpilot profile and a Finnrick record below two-thirds. Register, pull the certificate for your lot by its code, and prefer lots dated May 2026 or later if you need endotoxin and sterility lines.

What we liked

  • Names its third-party lab, Freedom Diagnostics Testing of Franklin, TN, and says each COA carries a search code checkable on the lab's site
  • Legal operator named (Melex Technologies Inc.) with a street address and toll-free phone
  • 30-day refund on unopened, unused products
  • States it is not a 503A compounding pharmacy or 503B outsourcing facility
  • Same-day dispatch by 2nd Day Air for orders before 2:00 PM ET, Monday to Friday

What we would want fixed

  • Prices and most of the catalog are hidden until sign-in
  • Trustpilot profile for simplepeptide.com removed; a separate Finnish-language profile exists under the wrong domain simplepeptides.com
  • The COA page is a lot-number search tied to the account page; whether certificates open without an account is unclear
  • Sterility, endotoxin and net-peptide-content testing appear only on COAs issued May 2026 or later
  • Finnrick, an independent testing aggregator, reports 28 pass / 19 fail on 47 tests (63%), with BPC-157 at 48% and CJC-1295 at 25%
