[hytereserach]

First. Who is this lab you have testing for you? Anybody heard anything about them?

 

[Great Northern Peptides]

Hello Hytereserach,

Thanks for reaching out and asking.

Freedom Diagnostics Lab is located in Franklin, Tennessee. They specialize in peptide testing — including accuracy, purity, and quantity. While they may not be the most widely recognized name yet, they’re rapidly gaining credibility in the peptide industry. Every month, I’m seeing more peptide suppliers transitioning to them.

We used Janoshik for years and were always happy with their quality, but the constant price increases, long turnaround times, and high shipping costs to Europe became difficult to manage. We still use Janoshik for HGH and HCG, since Freedom Diagnostics cannot legally test those products in the U.S.

About a year ago we began looking for a new primary lab, we reached out to several Canadian and American peptide suppliers for recommendations, and Freedom Diagnostics came up repeatedly.

We honestly couldn’t be happier with them. They’re professional, communicate well, turn around reports quickly, and their pricing is very reasonable.

If you’re concerned that their reports are always “sunshine and rainbows,” I completely understand — and I’d be happy to share examples of reports where they caught underdosed or low-purity peptides for us. In those cases, we had to discard those batches entirely. Their testing is thorough and honest.

If you have any other questions, feel free to ask — happy to help.

 

[Beginnerweak]

Hello,

Do you have any HGH stock as of now, didn't see any from your website.

 

[Great Northern Peptides]

Good evening Beginnerweak,

Thanks for the inquiry!

At the moment, we don’t have any HGH available for sale. It is something we plan to carry in the future, but for the next couple of months we’re focusing on expanding and diversifying our overall peptide selection. Our goal is to become your one-stop shop for all peptide needs, so we want to build out that foundation first.

Please keep an eye on this thread — I’ll make sure to post an update as soon as HGH is in stock. Hopefully in the meantime we can help you with any of your other peptide needs.

If you have any other questions please feel free to reach out anytime.

Gonna be honest, your gonna have a hard go on this website. Most people here know where to source the same products for about 1/8th or less the price your selling for.

 

[tweek]

Always nice to see more domestic sources for peptides but at these prices its not competitive whatsoever compared to the dozens of other long established guys.

Good morning joeblow543212,

Thanks for your comment.

We completely understand that there are several well-established Canadian domestic peptide suppliers out there — both on this forum and across the internet. We know we’re entering a competitive space, and our goal is to stand out by offering excellent customer service, fair pricing, a strong product selection, and fast, reliable shipping. We’re simply hoping people will give us a chance to earn their trust and become their go-to peptide supplier.

What you’re referring to — buying directly from China — can definitely be cheaper, but it also comes with significant risks. Issues like orders not arriving, very long shipping times, customs seizures, inconsistent quality, and not receiving what you paid for are all very real possibilities. And unless someone is doing their own testing, they’re essentially rolling the dice with what they’re putting into their body.

We work with multiple established manufacturers in China ourselves, and even with trusted suppliers there are still surprises when the test reports come back. Speaking personally, I would never use peptides that haven’t been tested first — the variability can be shocking.

You might be surprised to learn how many people here on Meso and elsewhere prefer to avoid that risk altogether. They’re willing to pay a bit more to know exactly what they’re getting, receive it in just a couple of days, and have access to responsive Canadian customer service. Honestly, we’re often surprised by how many people are hesitant to even order from reputable Canadian suppliers, never mind overseas sources.

We truly hope that anyone looking for a reliable Canadian domestic peptide supplier will give us a try and allow us the opportunity to earn them as a valued customer.

If you have any other questions, we’re always happy to help.

Hello Tweek,

We’re really excited to be part of the Meso community and to serve everyone here with Canadian domestic peptide options they can rely on.

To be honest, I was a bit surprised by your comment about our pricing. I’ve spent a lot of time researching reputable Canadian domestic peptide suppliers who provide proper lab testing. I even built a spreadsheet to track pricing across the industry because our goal has always been to offer the most competitive prices in the Canadian domestic market.

Right now, there are two other active Canadian domestic peptide suppliers on Meso. One is very well established and provides full lab reports on all products. The other is newer, with more limited testing available as they work toward building their reputation. I reviewed both of their price lists again this morning, and aside from two peptides being the same price, we are consistently 10–50% lower across the board. And that’s before applying our 10–20% volume discounts for larger orders.

It’s also important to note that every single peptide we sell is fully tested before it ever goes up for sale. All lab reports are posted here on Meso, listed on our website, and even the COA number is printed directly on each vial. Quality and transparency are absolutely essential to us.

If you happen to know of another Canadian domestic supplier offering better pricing with the same level of quality and testing, please feel free to send me their information — I’d genuinely appreciate the opportunity to look into it.

If you have any other questions, I’d be more than happy to help.
Wishing you a great day, and we look forward to hopefully becoming your trusted Canadian domestic peptide supplier.

Thats because your comparing websites lol.

Theres many domestic warehouses offering these peptides 30-50% below your advertised prices with testing to back it up

Then for majority of our members here we know where to get bulk peptides for 1/8 the price

No offense but you cant compete with these international company's with domestic warehouses

Good evening Tweek,

You’re absolutely right in what you’re saying — but I think it’s important that we compare apples to apples within the peptide market.

Realistically, customers have four main options when buying peptides:

1. Buy directly from Chinese labs
2. Buy from Chinese companies with warehouses in Canada
3. Buy from Canadian domestic suppliers (that’s the category we’re in)
4. Buy through an HRT clinic, usually based in the U.S.

Each option comes with its own set of pros and cons. Our focus isn’t on competing with every option — we’re specifically aiming to serve customers who prefer to buy from Canadian domestic suppliers. While many Meso members do choose China direct or domestic Chinese warehouses, there are still plenty who value domestic testing, fast shipping, and reliable Canadian customer service. Those are the people we’re aiming to serve.

Even though we may look new on the Meso forums as a peptide company, the reality is that we’ve personally been part of this Meso community for over a decade and have been involved in the bodybuilding and the PED world for a decade beyond that. Our experience is broad, and we stay very up to date — we still actively compete internationally in bodybuilding to this day.

I’m sharing this so people understand that the person “behind the curtain” is not new to this world at all — we take this very seriously and we’re very qualified in what we do.

Thanks again for the discussion and for taking the time to comment on our post. I genuinely appreciate it.

Your so called Canadian domestic is Chinese , theirs no way you’re getting peptides through clinics from the states to Canada.

Don’t feed that bs. Fix your prices or have no customers easy as that.

He's saying he's offering them domestically, that means they aren't shipping directly to customers from China or otherwise. He's not saying the product doesn't originate in China. How are you so fucking dumb as to not understand that?

Hello Axxium,

It seems there may have been a misunderstanding about what we’re offering, so I’d like to clarify to avoid any confusion.

You are absolutely correct — all peptides sold by Great Northern Peptides are manufactured in China. When we use the term “Canadian domestic peptides,” we are referring to the fact that the products are physically located in Canada, shipped from within Canada, and tested before sale. In our case, the lab testing is performed in the USA because Canadian regulations make peptide testing extremely limited here.

Within the peptide community, this is generally the accepted meaning of Canadian domestic:
Chinese-manufactured peptides that are stocked, tested, and shipped from within Canada.

I’m sorry for any misunderstanding you or anyone else may have had — it was never our intention to mislead in any way. Transparency is important to us, and we’re always happy to explain our sourcing and processes in detail.

If you have any questions or would like clarification on anything else, please feel free to reach out. I’m more than happy to help.

Still think untested Chinese domestic the way to go?

 

[thejoker]

Don’t worry about @Axxium he’s an imbecile and contributes zero to this forum.

Good luck on your endeavour here and you will need it as the peptide market is incredibly saturated now. I’m getting a half dozen ads on my Facebook feed every morning now for peptides it’s out of control.

It seems there is also a lot of new peptide testing labs coming online which will fuel some concern if these companies are actually legit. Janoshik is so well trusted these days that anyone else is viewed with skepticism.

Hey thejoker,

Thanks for the warm welcome to Meso — I really appreciate it.

You’re absolutely right, the peptide market is getting crowded with new companies popping up everywhere. Our goal is to separate ourselves from the rest by offering the best customer service, highly competitive pricing, full lab testing on every peptide we sell, and complete transparency at every step.

We genuinely believe that once customers give us a chance, they’ll see the difference in quality, service, and honesty — and the feedback we’ve already received from early customers has confirmed that.

Hopefully you’ll give us a try in the near future as well. If you ever have any questions, I’m always happy to help.

You talk of all these "surprises" from buying and testing from China , yet, I don't see any endotoxin or sterility testing done on any of your peptides ? I thought testing was most important, to you, and how you're justifying charging kit prices for single vials ??

Good afternoon Canuck83,

Thanks for the great question about our lab testing and procedures.

From the beginning, we’ve been very clear that we perform three core tests on every single batch of peptides we bring in:
Identity, Purity, and Quantity.
We believe these are the most important tests for ensuring customers receive exactly what they expect, and we run them religiously on every batch. Among “Canadian domestic” suppliers, very few actually do this consistently — many show no testing at all or only occasional random reports.

To give you an idea of why our testing matters so much, here are a few examples of the “surprises” we’ve encountered over the years:

• SLU-PP-332 testing as MOTS-c
• Epitalon coming back below 97% purity
• BPC-157 under-dosed by 25%

These are perfect examples of why we test every batch, and why customers can feel confident in what they’re receiving. All of the peptides listed above were never sold.

You’re absolutely correct that we could add endotoxin and sterility testing. Freedom Diagnostics does offer these tests, and we can include them in our protocol if our customers want that additional layer of assurance. To be honest, until your comment, no one has ever requested those specific tests — but if there’s demand for them, we’re more than willing to incorporate them.

There are many other tests that can be performed on peptides, such as:

• Heavy metal testing
• Chemical impurities
• Contaminant testing
• Stability testing
• Container/closure integrity
• Aggregation testing
• Extractables & leachables
• And more

As much as I would personally love to run every test available, doing so would push peptide prices far out of an affordable range. Our goal is to focus on the tests that matter most for safety, accuracy, and transparency — while keeping products accessible to the people who need them.

That said, we are always open to adapting our policies and procedures based on what our customers value. Transparency and trust are priorities for us.

Please let us know if you have any other questions or concerns — always happy to help.
