At a glance
- Simple Peptide is Melex Technologies, a real Florida corporation, not a spoof.
- Freedom Diagnostics COAs are public and searchable off-site by accession code.
- Finnrick: 15 of 33 customer samples passed. Failures are mostly fill, not identity.
- Trustpilot profile is gone. Yelp sits at 3.0 from 19 polarized reviews.
- Prefer Ascension for lot-matched public COAs and the ENHANCED 50% code.
The question people type is "is Simple Peptide legit," not "how pretty is the storefront." Those are different tests. A storefront can take a Visa charge, ship FedEx 2Day, and still hand you a vial whose fill does not match the label. A scam site usually fails the first test. Simple Peptide fails the second one often enough that you should read the lot paperwork before you do the reconstitution math.
This review is about Simple Peptide (singular) at simplepeptide.com. Buyers and Reddit threads pluralize it constantly. Same company. It is not Simply Peptides in the UK, and it is not simplepeptide.net, a clone-looking storefront that borrows the name.
Bottom line up front: Real Florida corporation, named founders, credit cards, phone support, and public Freedom Diagnostics COAs you can search off the vendor's site. Independent Finnrick sampling sits at 15 passes out of 33 tests. The failure mode is fill and dose accuracy, not "wrong molecule." Fine for a one-off on a well-studied compound if you match the lot to the PDF. For a repeat-buy protocol, Ascension Peptides with code ENHANCED is the sharper default.
What Simple Peptide actually is
Simple Peptide is the storefront of Melex Technologies Inc., a Florida profit corporation filed 18 July 2019 (document P19000056045, EIN 84-2350728). Sunbiz still lists it ACTIVE. The 2026 filings put the principal address at 10055 Yamato Road, Boca Raton, FL 33498. Alexander Ehrenthal appears as President and CEO. A November 2025 Palm Beach County complaint names Alexander as President and Melissa Ehrenthal as CEO.
The domain was registered 19 December 2023. The About page says the shop started late 2023, first as an importer, then as a customer of a US manufacturer they describe as cGMP. They do not name that manufacturer. The Yelp and footer address (6586 W Atlantic Ave Ste 1112, Delray Beach) is a mailbox in a shipping store. The terms page uses a Tampa suite that reads like a virtual office. That is address salad, not proof of fraud. It does mean you are not walking into a lab.
They sell research-use-only lyophilized vials, capsules, a nasal reconstitution solution, and a consumer layer (toothpaste, dissolving strips, an organ complex) that sits awkwardly next to the "not 503A / not 503B / not for human use" legal copy. GLP-1 SKUs are code-named on the public catalog (SP-1SG for a semaglutide analogue; SP-2TZ capsules are login-gated). That coding is a regulatory tell, not a quality tell.
The testing story: public COAs, one lab
This is the part Simple Peptide does better than most gray-market shops. There is a public certificate archive and a "View COA Archive" widget on product pages. That is not request-only.
The PDFs we inspected name Freedom Diagnostics in Franklin, TN. Methods on the BPC-157 capsule lot BPCC-052026-7 (accession 2605220308, search code Simp2605220308) were HPLC-UV purity, LC-MS identity, and endotoxin (LAL). Identity confirmed. HPLC-UV 99.95%. Net content 477 mcg against a 500 mcg label. Endotoxin passed. The product page rounded that lot to 100.0%.
PeptideBenchmark's 10 August 2026 sync found 139 of 183 certificate origins resolving live in Freedom's public index. Merit Verified (April 2026 snapshot) counted 275 Freedom COAs and a single lab. Freedom also lists Simple Peptide as a "Testing Partner" on its own site. That is not a fake-COA finding. It is an independence question. A lab that markets vendors as partners is a different posture than an outside lab whose only job is the PDF.
Why the PDF still matters, even when the lab relationship is cozy: illegal peptide vials seized in Europe have shown purity as low as 5 to 75% on cysteine-containing sequences, plus arsenic and lead above parenteral limits (Janvier et al., Talanta 2018, PMID 30029448). Online "semaglutide" vials bought without a prescription have shown peptide purity of 7.7 to 14.4% against a 99% label claim (Ashraf et al., JMIR 2024, PMID 39509151). Identity and quantity are not the same test. Controlling agencies treat LC-MS identity plus a separate quantitation method as the practical screen (Vanhee et al., Talanta 2015, PMID 26003685).

What independent sampling found
Vendor COAs tell you what the vendor's chosen lab wrote. Customer-submitted testing tells you what showed up in the vial a buyer received.
Finnrick's live Simple Peptide page (read 14 July 2026, still the current board as of this writing) shows 33 tests, 15 pass / 18 fail, 60%, rank 271 of 301. Identity is not the usual failure. Fill and dose accuracy are. Product-level ratings on that board: tirzepatide 80% (6 tests), retatrutide 71% (11), ipamorelin 69% (3), semaglutide 65% (4), melanotan II 49% (3), BPC-157 44% (3), CJC-1295 23% (3). A 9 July 2026 retatrutide row is a Fail sitting next to Passes.
That matches a story the owner already told in public. In mid-2025 replies on Trustpilot and Reddit, Alexander said the manufacturing lab was losing about 5% of peptide content in lyophilization and that they then overfilled by 15%. Overfill is kinder than a short vial. It is still a labeling problem if you calculate concentration from the printed milligrams.
An earlier 29-test snapshot circulated in June 2026 with 100% identity pass and one 30 mg tirzepatide vial assaying about 58.5 mg. Treat that as a dated snapshot. The live Finnrick board is the one that counts, and it is mixed.
Reputation after Trustpilot vanished
Simple Peptide used to have a busy Trustpilot page (reviews in 2025 quoted it around 4.7 from a few hundred ratings). That profile is gone. Peptide Grades noted the removal in March 2026. PeptideBenchmark still shows no linked Trustpilot page in August 2026. We do not know why Trustpilot pulled it. Do not invent a reason, and do not cite a current star rating that does not exist.
What is left is noisier:
- Yelp (Delray listing, August 2026): 3.0 from 19 reviews, polarized. 2026 complaints include an unfulfilled order, a cancel-while-pending that was ignored, and a $285 unordered charge. Praise, when it appears, is about FedEx speed and the owner calling back.
- Reddit is split and affiliate-contaminated. The long December 2024 r/PeptideForum thread has people who got overnight replacements and people who got no-effect GLP-1s. A later r/PeptideDiscussion fight posted Chromate and Trust Point underfills next to a Freedom PDF that read closer to label. Treat threads as anecdotes, not a rating.
- Scamadviser scores the domain as likely safe. That only means the site is not an obvious phishing clone. It does not grade the powder.
There is also a real lawsuit, and it is not an FDA case. In November 2025 Melex Technologies sued Daniel and Heather Baum in Palm Beach County (business tort / trade secrets). Melex is the plaintiff. No FDA warning letter, seizure, or class action turned up for Simple Peptide, Melex, or the Ehrenthals. Shutdown rumors on Reddit do not match a live site, an active Sunbiz filing, or an amended annual report dated 5 August 2026.
Catalog, prices, and the clone
Public sticker prices (August 2026): BPC-157 10 to 20 mg at $55 to $85; TB-500 10/15 mg at $65; Ipamorelin 10 mg at $65; Sermorelin 5/10 mg at $49 to $79; GLOW 50/10/10 at $115; BPC-157 500 mcg x 100 capsules at $170; SP-1SG 10 mg on sale at $74.40. Volume breaks start at 5 and 10 units. Homepage copy promises FedEx 2Day; the shipping page is US addresses only, while the FAQ still claims "many countries." Use the shipping page as the rule.
Stay on simplepeptide.com. simplepeptide.net is a same-name collision with a SIMPLE15 coupon and terms that copy the .com language, including a "Verified Peptide" typo. If a review or ad sends you to .net, leave.

Simple Peptide is one of the easier US shops to identify as a real business and to pull a third-party PDF for. That answers "is it a scam site?" with no. The reason we still point repeat protocols at Ascension is lot-level fill control and a lab relationship that is not marketed as a partnership, plus a discount that does not expire after the first cart. For the wider ranking, use the best legit peptide vendors list.
Who this vendor is for
Buy from Simple Peptide if you want a US card-checkout shop, you will match the printed lot to a Freedom PDF before you reconstitute, and you are running a well-studied compound such as BPC-157 or TB-500 as a one-off. Use the BPC-157 dosage chart for the protocol math, not the product-page marketing copy.
Do not use it as your default if you need tight fill control (GLP-1 reconstitution charts punish a 15% overfill), if you were about to trust a TikTok "Grade A" graphic that contradicts the live Finnrick board, or if you landed on simplepeptide.net.
For a research plan that spans several compounds and several months, Ascension Peptides is the sharper default at 50% off with code ENHANCED, with pre-formulated stacks and a public COA workflow. Cross-check independent purity data in the lab-tests library before either cart.
