Simple Peptide is the trading name of Melex Technologies Inc., a company in Delray Beach, Florida that wears a “Since 2019” badge on its storefront, says it fully launched in 2023 and describes itself as family-run. The catalog, as far as a visitor can see it, spans lyophilized vials, dissolvable “BioStrips”, oral peptides and a skincare line, and it includes GLP-class products. The one thing a first-time reader should know is that the company is unusually forthcoming about who it is and unusually guarded about what it charges. That combination shaped the whole of our check.
We read the public pages the way a cautious buyer would. We looked for the operator’s legal name, a street address and a phone number, opened the certificate page, read the third-party testing page, the shipping and returns page and the about page, and then went to the public record for warning letters, review-site history and independent test results. Where the site asked us to create an account to see more, we stopped, because a reader deciding whether to trust a supplier should not have to hand over an email address first.
The claims this storefront makes
The central claim is about testing. Simple Peptide says every lot is tested by Freedom Diagnostics Testing in Franklin, Tennessee, using LC-MS to confirm identity and HPLC-UV to measure purity, and that each certificate carries a search code that can be checked on the lab’s own website. From May 2026 onward the company says certificates also report sterility, endotoxin and net peptide content. Alongside that sits a finished-lot standard of 99 percent purity or better where the molecule supports it, with any exception documented on the lot certificate.
The remaining claims are about the business. The company states that it is not a 503A pharmacy or a 503B outsourcing facility, which is the correct position for a research supplier. It promises same-business-day dispatch by 2nd Day Air for orders placed before 2:00 PM Eastern, Monday through Friday, and a 30-day refund on unopened, unused products. It does not claim GMP, ISO or cGMP certification for itself, and the testing page makes no ISO 17025 claim for the lab, which we note as a point in favor of restraint.
What held up when we checked
The identity claims are the strongest part of the record, and they held up completely. The legal operator is named. The address, 6586 W Atlantic Ave Ste #1112, Delray Beach, FL 33446, the toll-free number, 1-877-711-0702, and the support email, [email protected], are all published where a visitor can find them. A research-use-only disclaimer is present. In a market where many storefronts offer a contact form and nothing else, this is the baseline we wish every supplier met.
The testing claim is specific in the ways that matter. Naming a lab with its city, naming the methods and pointing to a search code that resolves on the lab’s site are all checkable statements, and the record treats the per-lot claim as supported. The purity guarantee is also better written than most. Rather than promising 99 percent across the board, it concedes that some molecules will not reach that figure and commits to saying so on the certificate. That is how a guarantee should read.
The commercial terms are concrete. Shipping is by UPS or FedEx 2nd Day Air within the United States, with USPS for PO boxes, and there is no international service. Payment is by card or bank transfer. Returns run for 30 days on unopened, unused products in original condition, opened products are handled case by case, the customer pays for trackable return shipping, and refunds arrive 7 to 10 business days after inspection. None of this is generous, but all of it is stated.
What did not, and what we could not verify
The certificate program has a wall in front of it. The certificate page is a lot-number search tied to the my-account page, and the record cannot establish whether a certificate opens for a visitor who has not registered. That matters because the value of a named lab and a search code is that a stranger can check them before ordering. If the check requires an account, the company has done the hard part of a transparency program and then hidden the result. We record public certificates as unknown rather than confirmed.
Prices are hidden in the same way. Most of the catalog and every price sit behind sign-in, so we could not record a BPC-157 price or place the company on the market’s price scale. A buyer comparing suppliers simply cannot do so here without registering. The Trustpilot history is also a mark against the record: the profile for simplepeptide.com has been removed by Trustpilot for going against its guidelines, and the only surviving page is a Finnish-language listing under the wrong domain, simplepeptides.com, which does not help anyone.
Then there is the independent record. Finnrick, an independent testing aggregator, reports 28 passes and 19 failures across 47 tests, with the most recent test dated October 8, 2026, for a 63 percent rating. Finnrick’s figures for BPC-157 and CJC-1295 are 48 percent and 25 percent respectively. We did not run these tests and cannot vouch for them, but a stated standard of 99 percent sits awkwardly next to an outside pass rate below two in three. The sterility, endotoxin and net-content testing also only begins with certificates issued in May 2026, so older lots carry identity and purity alone. The product count is not published. No FDA warning letter naming Simple Peptide was found as of October 19, 2026.
Our read
Simple Peptide has done the identity work properly, named its lab and written a guarantee that does not overpromise, and that puts it ahead of a good share of this market. What it has not done is let a stranger see the certificates or the prices, and the independent test record Finnrick has compiled does not support the purity standard the company advertises. A buyer who already has an account and can read a current lot certificate with a search code that resolves at the lab is on reasonable ground. A buyer who cannot, or who wants to compare prices before committing, is being asked to trust first and verify later, and we would put two questions to the company before ordering: whether a certificate can be read without an account, and why outside samples pass at the rate Finnrick reports.
