What is on the record

Apex Peptides

Offline

apexpeptides.com · 23 Sep 2026

Confirmed

On 23 September 2026, federal agents searched a business address in North Sioux City, South Dakota, and a home in Dakota Dunes. The US Postal Inspection Service led, with the FBI, IRS Criminal Investigation and local police. Apex Peptides is one of several Apex-named businesses listed at that address [1][3].

Two days later its website said it was temporarily closed, with most products removed [2]. On 30 September 2026 the site showed only a maintenance page.

Not known

No charges have been announced. What the investigation is about, and whether it concerns peptides, has not been made public.

Chemyo

Closed

chemyo.com · 8 Sep 2026

Confirmed

Its site says it permanently closed on 8 September 2026. Orders placed before that date will be fulfilled, and it no longer takes payment [4].

Not known

No reason is given.

Eternal Peptides

Closed

eternalpeptides.com · Sep 2026

Confirmed

The store is gone. The site shows a thank-you note and says customer support runs until 30 September [5].

Not known

The exact closing date and the reason are not stated.

Strate Labs

Closed

stratelabs.com · 2026

Confirmed

Its site says it has permanently closed, and gives the reason as the regulatory landscape around the industry having shifted in ways that make it impossible to keep operating [6].

Not known

The notice carries no date.

Peptide Sciences

Closed

peptidesciences.com · 2026

Confirmed

Its site says it has voluntarily shut down operations and stopped selling research products [8].

The same notice says any site or person claiming to be its successor, or to sell its products, is unauthorized [8].

Not known

The notice carries no date and gives no reason.

Science.bio

Closed

science.bio · 2026

Confirmed

Its site says it has decided to permanently close and stop selling research products [7].

Not known

The notice carries no date and gives no reason.

Paradigm Peptides

Closed

paradigmpeptides.com · Sentenced 2026

Confirmed

The business, based in Michigan City, Indiana, shipped products from April 2019 to March 2024. Its owner and an employee pleaded guilty in federal court on 10 December 2025 [9].

The owner was sentenced to 70 months in prison and the employee to 16 months, with $78,317.52 in restitution [10]. The Justice Department says some products sold as SARMs contained testosterone [9], and CBS News reports the owner admitted knowing products were sold for human use [11].

Not known

Nothing material. The business itself stopped selling in 2024; the court case ran into 2025 and 2026.

If your supplier closed

Four things to check before you order elsewhere

1. A certificate for the exact compound. It should name the independent lab, the method and the purity, and match the compound and size you are buying. A generic "tested" badge is not a certificate.

2. A lab you can check. The lab should be a real, named business you can contact. If you cannot find the lab, you cannot trust the report.

3. No "successor" claims. Be wary of any site presenting itself as the new home of a closed brand. Peptide Sciences' own notice says anyone claiming that is unauthorized.

4. Clear research-use terms. A serious supplier says plainly that its products are for laboratory research only, and does not sell them with instructions for personal use.

Our supplier checklist has fourteen checks you can run on any seller, us included. Every compound we sell has its certificate on its product page, and the certificate archive lists them all.

Questions

Common questions

What happened to Apex Peptides?

Federal agents searched a North Sioux City, South Dakota, business address where Apex Peptides is listed on 23 September 2026, and its website went offline soon after. As of 30 September 2026, no charges have been announced and the reason for the search has not been made public.

Did Peptide Sciences shut down?

Yes. Its own website says it has voluntarily shut down and stopped selling research products. It also says anyone claiming to be its successor is unauthorized.

Is Chemyo closed?

Yes. Its website says it permanently closed on 8 September 2026 and no longer takes payment.

Why are so many peptide vendors closing?

Most closure notices give no reason. Strate Labs says the regulatory landscape changed. Separately, the FDA sent warning letters to a number of online peptide sellers in 2025 and 2026, and the Justice Department prosecuted the owner of Paradigm Peptides. We do not guess at why any single company closed.

Is SBz Industries connected to any of these companies?

No. We are not a successor to, a partner of, or a reseller for any company on this page, and we do not sell their products.

How do I check a new supplier?

Ask for a certificate of analysis for the exact compound, from a named independent lab, and check that the lab and report are real. Our supplier checklist has fourteen checks you can run on anyone, us included.
