Ever since Proven Peptides shut down in 2020, there’s been a huge rift in the SARMs community.

They have been selling SARMs since 2015 and have rightfully earned their spot as one of the best SARMs vendors on the market.

This article will tell you a bit about what happened, why they closed and where to find the best Proven Peptides alternatives!

Why Did Proven Peptides Shut Down

When the red pop-up on the top of their website appeared, stating they were gone for good, many people brought forth their own theories.

The most serious conjecture talked about total doom and gloom; the end of SARMs and an outright ban on their sales.

Another theory connected two dots and claimed that it was due to the new LGD-4033 ban that affected many vendors.

The original company claimed a trademark on Ligandrol and went after vendors selling it under the names “LGD-4033” and “Ligandrol”.

Some people also guessed that the main reason behind the ban was the massive advertising campaign Proven Peptides had.

They basically think it was due to the company being “too much in your face” that the FDA had stepped in.

None of these postulations paint an accurate picture of what had actually transpired.

According to the US Department of Justice and the criminal charge reported by SupplySide, the owner of Proven Peptides engaged in false promises and mislabeling of their products.

Prosecutors added that the owner failed to register the facility where their SARMs were produced.

On top of that, the main allegation comes from the fact that Proven Peptides made claims that SARMs would have certain effects on their users.

This goes against the holy grail of SARMs being used for research purposes only.

Proven Peptides had disclaimers on their website stating SARMs were for research purposes only.

However, prosecutors said the owner knew their customers were imbuing SARMs and were using the disclaimers to hide illegal actions.

The owner pleaded guilty in August 2021 to conspiracy to defraud the United States, agreed to forfeit about $10.7 million and faced up to five years in prison and a $250,000 fine. The same charge listed SARMsX among his businesses (see our SARMsX review).

I’m 100% sure Proven Peptides will never sell SARMs again.

With that being said, what are the best alternatives to this vendor?

The Best Alternatives to Proven Peptides

I’ve been studying SARMs for over 7 years now and have gone through hundreds of vendors.

Many of them fail to disclose their lab results or post outdated reports from a few years back.

These are just some of the things you have to pay close attention to.

For that very reason, we keep a page of SARMs company recommendations, with what we check and our current pick.

Be sure to check it out if you’re looking for a good Proven Peptides alternative.

Our current pick

Our current pick for buying SARMs, PCT compounds and peptides is SwissChems. The reasons are ones you can check on its own pages:

  • Lot-specific lab reports. SwissChems publishes lot-specific certificates of analysis on its independent test results page (131 reports were listed when we checked on 30 October 2026). Each report names the product, the lot and the lab. The report we opened, for GW-501516 (cardarine) lot J26CYG, was issued by Freedom Diagnostics Testing on 3 October 2026 and shows identity confirmed by LC-MS and 99.79% purity by HPLC.
  • A written quality claim process. Its quality assurance page sets out a written claim process: if your own third-party lab test (with chromatograms and the lot number) shows a problem within 30 days of delivery, SwissChems says it will review it and, if confirmed, replace the product or credit it and pay up to $100 of the testing fee.
  • Range. The shop lists SARMs, PCT compounds (tamoxifen, clomiphene, enclomiphene, raloxifene, anastrozole, letrozole), around 50 peptides, about 30 nootropics and bioregulators in one catalog.
  • Shipping and payment. US orders ship by USPS or FedEx; international orders by USPS. It takes US Visa and Mastercard, bank transfers (ACH, Zelle, Interac) and crypto. No PayPal.

More detail, including what we would like SwissChems to do better, is in our SwissChems review. You can also visit SwissChems directly.
