Peptide Vendor Shutdowns: What Happened and What to Do

By Editorial team. Updated Oct 14, 2026. Awaiting editor sign-off

Research-peptide vendors close often, and sometimes with no warning. Some closures follow enforcement action, some are voluntary, and some are never explained. This page records notable cases from 2024 to October 2026 with sources. It then sets out what to check when a vendor disappears. Our alerts page tracks new closures, warning letters, seizures and lawsuits as they happen. Each vendor page shows that vendor’s current status.

Notable closures, seizures and prosecutions

Peptide Sciences

Peptide Sciences was a US research-peptide seller [1]. A snapshot of its homepage from March 8, 2026 shows a notice saying the company “has made the decision to voluntarily shut down operations and discontinue the sale of our research products” [1]. The notice gave no reason, and we haven’t found an official explanation. Explanations circulating online are speculation.

Science.bio

By February 8, 2026, Science.bio’s homepage said it “has permanently closed” [2]. Its current notice adds a warning: any website, entity or individual claiming to be Science.bio, a successor to it, or a seller of its products is fraudulent and unaffiliated [3]. Closures of well-known brands attract impostors, and this is the clearest example.

Strate Labs

An archived copy of Strate Labs’ homepage from July 28, 2026 shows a closure notice. It says the regulatory landscape had “shifted in ways that make it impossible for us to continue operating” as before. It also says pending orders would ship as scheduled [4].

Chameleon Peptides

Chameleon Peptides’ storefront now says it is closed for new purchases. Existing customers can still sign in to view order history and lab reports, but new account registration is closed [5]. A review site dates the closure to September 27, 2026 [6].

Amino Asylum

Amino Asylum is no longer trading. Vendor and affiliate sites date its disappearance to mid-2025, and many describe a June 2025 FDA raid. We have not found an FDA, Department of Justice or court record confirming one, so we don’t repeat that claim as fact. Some sites have also mixed up the Amino Asylum story with the separate Paradigm Peptides prosecution. What we can document is the domains. An archived capture from April 2, 2026 shows aminoasylum.com redirecting to ww1.aminoasylum.com, a pattern typical of domain-parking services [7]. When we checked on October 15, 2026, the store’s aminoasylum.shop address redirected to a coupon site, peptidecoupons.com (see its profile).

Paradigm Peptides

Paradigm Peptides sold peptides, hCG and products labeled as SARMs online. Investigators found that many products sold as SARMs actually contained testosterone. Both defendants pleaded guilty on December 10, 2025. On July 30, 2026, the owner was sentenced to 5 years and 10 months in prison and a company employee to 1 year and 4 months. The US Attorney’s Office says anyone who bought from the business between April 2019 and March 2024 may be a victim [8].

Canada and Australia

In Canada, Prime Research of Sherbrooke, Quebec, stopped advertising and selling and took its website down at Health Canada’s request after seizures [9]. Canada Peptide’s products were seized later the same year [10]. In Australia, the TGA announced in September 2026 that the former company and directors behind BioV8 will face court over alleged unlawful advertising of peptides [11]. These are allegations; the court hasn’t ruled.

When a vendor goes dark: what to check

1. Confirm it at the source. Type the vendor’s domain yourself and read any notice there. Don’t rely on screenshots, social posts or direct messages.
2. Distrust “successors”. A new site claiming to be the old vendor under a new name is the most common follow-on scam. Science.bio says outright that such sites are fraudulent [3]. Look up any “new home” in ICANN Lookup and the Wayback Machine (see how to check a vendor). Our guide to look-alike peptide vendor sites lists the look-alikes we’ve found.
3. Deal with unshipped orders in writing. Email support, keep copies, and note the dates.
4. Dispute card payments in time. For US credit cards, a dispute letter must reach the issuer within 60 days after the first bill showing the error. Goods not delivered as agreed count as a billing error [12]. Don’t wait to see whether a “delayed” order turns up.
5. Save your records while you can. Download invoices, order history and any lab reports or COAs for products you bought. Some vendors leave a customer archive open for a while [5], but it won’t last.
6. Don’t buy “leftover stock” from third parties. Stock passed on after a closure has unknown storage history and no one accountable for it.
7. Treat product you already have as unverified. A closure doesn’t prove anything was wrong with a product. It does mean nobody stands behind it. Only an independent test can tell you what is in a vial, and only for that vial (see peptide testing explained).

How we track vendor status

We check every listed vendor’s website on a schedule and record whether it is live, down, redirecting, parked or closed, along with the date we checked. When a vendor closes, its page stays up with the evidence and a list of alternatives that pass our transparency checks. We don’t recommend unverified “successor” sites. If you spot a closure we’ve missed, our contact page explains how to send it with a source.
