Paradigm Peptides Review: What Happened and Where to Buy Instead
If you landed on this page looking for a Paradigm Peptides review, I need to bring you up to speed on something important.
Paradigm Peptides is done.
The owner, Matthew Kawa, pled guilty to federal charges in December 2025. The U.S. Attorney’s Office for the Northern District of Indiana found that products Paradigm sold as SARMs actually contained testosterone, which is a controlled substance. His sentencing is scheduled for March 2026.
This isn’t a rumor. This is a federal case with a guilty plea. The Department of Justice has a public page documenting the entire investigation.
If you bought anything from Paradigm Peptides between April 2019 and March 2024, the government considers you a potential victim in this case.
I’ve been in this industry for over 10 years. I’ve watched companies come and go, and I’ve seen what happens when suppliers cut corners. This is exactly why I pound the table on sourcing from companies that actually test their products. When you’re putting something in your body, you need to know what’s in the vial. Paradigm customers thought they were getting SARMs and they were getting testosterone instead. That’s not a quality control issue. That’s fraud.
Let me break down what happened, why it matters, and where you should be buying your peptides instead.

What Happened to Paradigm Peptides?
Paradigm Peptides was a U.S.-based supplier operating out of Michigan City, Indiana under the business name Paradigm R.E. LLC. They sold peptides, SARMs, and hCG through their website paradigmpeptides.com.
On the surface, they looked legitimate. They had a professional website, talked about third-party testing, and built a decent following. They had a 4.7 star rating on Trustpilot. People trusted them.
Then federal investigators started looking under the hood.
What they found was that many of the products labeled and sold as SARMs actually contained testosterone. Let that sink in for a second. People who thought they were buying research SARMs were unknowingly taking a controlled substance. The health implications of that are serious. Testosterone has real physiological effects, and taking it without knowing you’re taking it means you can’t monitor for side effects, adjust dosing, or make informed decisions about your health.
Matthew Kawa and his sister Jennifer Stechkober, who worked for the company, both pled guilty in December 2025. Kawa’s sentencing is set for March 24, 2026.
The website now displays a message saying Paradigm Peptides is closed and no orders will be fulfilled.
Why This Matters for Every Peptide Buyer
The Paradigm Peptides case isn’t just about one bad company. It’s a warning about the entire peptide and research chemical market.
Here’s the reality most people don’t want to hear. There is no shortage of suppliers out there selling products that don’t match their labels. Some are under-dosed. Some are contaminated. And as we just saw with Paradigm, some contain completely different substances than what’s advertised.
This is why third-party testing isn’t just a marketing buzzword. It’s the only thing standing between you and a vial of something you didn’t sign up for.
When I say third-party testing, I mean independent lab verification of every batch. Not in-house testing. Not a certificate of analysis from the manufacturer in China. An actual independent lab in the United States running purity, identity, and potency tests and publishing the results.
If your supplier can’t show you batch-specific third-party test results, walk away. Period. The Paradigm situation is proof of what happens when people trust a brand name without verifying what’s in the product.
What Should Former Paradigm Peptides Customers Do?
If you previously ordered from Paradigm Peptides, here’s what I’d recommend:
Stop using any products you still have from them. You don’t know what’s actually in them. Federal investigators confirmed that product labels did not match contents. Don’t take the risk.
Check if you’re considered a victim. The U.S. Attorney’s Office has set up a process for customers who purchased between April 2019 and March 2024. You can contact their office at 219-937-5500.
Find a new supplier you can actually verify. More on that below.
Where to Buy Peptides Now: BioEdge Research Labs
After the Paradigm situation, I’ve gotten a flood of questions from people in our community asking where to buy now. My answer is the same one it’s been for years.
Here’s why I trust them and why I recommend them to everyone in our community:
Third-party lab testing on every batch. Not some batches. Not when they feel like it. Every single batch gets tested by an independent lab before it ships. You can verify what you’re getting.
Cold-chain shipping. Peptides degrade in heat. BioEdge ships with proper temperature control so your product arrives intact and at full potency. This sounds basic but a shocking number of suppliers skip this step.
Consistent quality. I’ve been working with BioEdge long enough to know what I’m getting every time I order. The quality doesn’t fluctuate batch to batch. That consistency matters when you’re building a protocol you want to rely on.
Transparent operations. After what happened with Paradigm, transparency isn’t optional anymore. You need to know who you’re buying from, how they test, and what’s actually in the vial. BioEdge delivers on all of that.
Use code PEP10 for 10% off your order.
Important: Make sure you’re on the real BioEdge site. There are copycats out there building sites with similar names trying to ride BioEdge’s reputation. The only official site is bioedgeresearchlabs.com. If you land on anything else with “bioedge” in the name, it’s not them. Bookmark the real URL and don’t trust random links from forums or social media. After what happened with Paradigm, the last thing you want is to get burned by a knockoff supplier pretending to be someone they’re not.
Whether you go with BioEdge or someone else, here are the non-negotiable things to look for after the Paradigm collapse:
Third-party testing with published results. Ask for batch-specific certificates of analysis from an independent U.S. lab. If they can’t provide it, they’re not worth your money or your health.
Reputation that holds up under scrutiny. Don’t just look at Trustpilot scores. Paradigm had a 4.7 and their owner pled guilty to federal charges. Look at community forums, ask people who have used the products, and check if the company has a real track record beyond paid reviews.
Proper shipping and storage. Peptides are fragile. If a company is shipping vials in a padded envelope in July with no temperature control, they don’t care about product integrity.
Clear labeling and honest communication. If a company is vague about what’s in their products, how they’re made, or where they’re sourced, that’s a red flag. The companies worth buying from are the ones that over-communicate on quality.
Payment processing stability. This is an underrated indicator. Legitimate suppliers maintain stable payment processing because they’re not doing things that get them flagged. If a company is constantly switching processors or only accepting crypto, ask yourself why.
Peptides can get expensive, but as an FYI - BioEdge is doing 15% off this month (code mars15 at bioedgepeptides.com), one of the few suppliers that consistently delivers what their lab reports claim.
Products Paradigm Peptides Used to Carry
For reference, Paradigm used to offer BPC-157, TB-500, Melanotan 2, and various SARMs. If you were using any of these from Paradigm and need to find a replacement source, BioEdge carries high-quality versions of the most popular peptides.
Here are some quick alternatives for what Paradigm customers were commonly buying:
BPC-157 — One of the most popular healing peptides. Known for gut health, injury recovery, and tissue repair. BioEdge carries this and it’s one of their best sellers.
TB-500 — Often stacked with BPC-157 for enhanced recovery. Works systemically throughout the body rather than locally.
Melanotan 2 — Used for tanning and other research applications. Make sure you’re getting it from a tested source because purity matters significantly with this one.
You can find all of these at BioEdge Research Labs. Use code PEP10 for 10% off. Make sure you’re on the real site at bioedgeresearchlabs.com — there are copycat sites popping up using similar names trying to ride their reputation.
For SARMs specifically, I’d be cautious right now. The regulatory environment around SARMs is getting tighter, and the Paradigm case is going to accelerate that. If you’re set on running SARMs, do your homework on the supplier and demand third-party testing before you buy.
The Lesson From Paradigm Peptides
The Paradigm Peptides story is a cautionary tale that every peptide buyer needs to hear.
A company can have a professional website, good reviews, and all the right marketing. And still be selling you something completely different from what’s on the label. The only protection you have is verification. Third-party testing. Lab results you can actually check. A supplier with a track record that holds up when you dig into it.
I’ve been doing this for over a decade. The companies that last in this industry are the ones that do things right from the start. The ones that cut corners eventually get caught. Paradigm got caught. And their customers paid the price.
Don’t let that be you.
Source smart. Verify everything. And if something seems too cheap or too good to be true, it probably is.
Stay sharp.

I’m Joe Mars, and I’ve dedicated the past ten years to understanding peptide therapy, longevity, and how to optimize the body through practical, real-life testing. My journey started when I was tired, inflamed, and aging faster than I should have been. Clear information on peptides was almost impossible to find, so I dug in, researched nonstop, and tested protocols on myself.
Over the years, I have learned from experts like Jay Campbell, Dr. Seeds, Jim LaValle, and Ben Greenfield, and I have completely transformed my health. Now in my fifties, I feel stronger and sharper than I did in my twenties. That experience is why I write. I want to give people simple and honest guidance so they can use peptides safely and effectively.
I believe in data, smart protocols, and taking responsibility for your own health. You are the protocol. Your habits, your consistency, and your awareness shape your results. Through The Peptide Report, I share what actually works so you can make informed decisions and build a healthier, more resilient body.
