peptidesciences.com now serves a notice in place of its storefront: the company has voluntarily shut down and discontinued the sale of its research products, keeps its trademarks and will enforce them, and calls any site claiming to be its successor fraudulent. The notice carries no date and no reason. Read on the company's own domain, 29 September 2026.
The homepage of peptidesciences.com no longer shows a catalog. It states that after careful consideration the company decided to voluntarily shut down operations and discontinue the sale of its research products; that it retains all rights in its name, brand, trademarks and goodwill and will continue to protect and enforce them; and that it is grateful to its customers. A second paragraph is a warning: any website, platform, entity or individual claiming affiliation with Peptide Sciences, representing itself as a successor, or claiming to sell its products is unauthorized and fraudulent, and the company authorizes no third party to use its name.
That is the whole of what the company has said. There is no date on the notice, no reason beyond "voluntarily", no mention of open orders, refunds or support, and no product list. Every more specific claim you will find elsewhere — a March date, an enforcement trigger, a buyer — is somebody else's inference. We record what is on the company's own domain and nothing more.
The notice says nothing about orders or support. If you paid by card, your issuer's dispute process is the practical route; if you paid by a rail with no dispute mechanism, we know of no channel. We would rather say that than invent a support address.
Is not Peptide Sciences. The company's own notice calls any successor claim or any sale under its name unauthorized and fraudulent. A new domain using the name, a "discount code" and a payment rail you cannot dispute is the pattern that follows every closure on our closures record.
Peptide Sciences closed before we scored it, so we hold no basket to match line by line. What we can offer is the top of a rubric applied identically to every vendor we cover.
Print a closure date the company has not given, repeat an enforcement story with no record behind it, or name a "successor" the company itself calls fraudulent. The closures hub keeps the record for Peptide Sciences, Science.bio, Amino Asylum, Chameleon and Chemyo, and separates what is verified from what is merely repeated.
Where the evidence points
For the peptides Peptide Sciences listed, the closest thing to a like-for-like on the evidence is the top of the scoreboard above. Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Purgo Labs is our primary affiliate partner; we earn a commission on that link. The score is computed from published evidence and does not read partner status.
Yes. peptidesciences.com serves a notice in place of its storefront stating that, after careful consideration, the company decided to voluntarily shut down operations and discontinue the sale of its research products. We read it on the company's own domain on 29 September 2026.
The notice is undated. Several industry sites report early March 2026, but none cites a primary source, so we do not print a date. If the company dates it, we will.
The company has not said beyond the word 'voluntarily'. We have found no FDA warning letter, DOJ action or court record naming Peptide Sciences, and no company statement giving a reason. Anything more specific you read elsewhere is that site's inference, not the company's words.
The notice says nothing about open orders, refunds or support — unlike Chemyo's, which does. If you paid by card, the practical route is your card issuer's dispute process, which usually runs 60–120 days from the charge; if you paid by a rail with no dispute mechanism, we know of no channel. We would rather say that plainly than guess.
The company's own notice says any website, platform, entity or individual claiming affiliation with Peptide Sciences, representing itself as a successor, or claiming to sell its products is unauthorized and fraudulent, and that it does not authorize any third party to use its name, brand or trademarks. Treat any store using the name accordingly, whatever its discount code says.
On the evidence, Purgo Labs: 10/10 on the same 10-point rubric every vendor on our scoreboard is scored on — named laboratory, lab-verifiable certificates with measured net content, open prices, a published company, and an independent review base. Code HEALTH is 20% off every order; it is an affiliate code, disclosed, and does not touch the score. The scoreboard ranks 60-plus vendors on the same criteria if you want to compare.
No. It closed before we scored it, so we hold no certificate, price or review record for it and cannot say how it would have scored. Our comparison page with Purgo Labs is kept for readers who search for it, marked closed.
