9 Best Peptide Companies and Sources

With so many options online, and Bezos not looking like he's gonna stock the stuff soon, how do you know where to get your peptides? Let's find out.

Let’s face it. You’re spoiled rotten, aren’t you? You have so many options for Peptide Suppliers you’re not even sure which one to go for anymore! This one has great marketing, but that one has better Third Party Tested results.

Obviously, you should go for the first, right? Fear not my friend for in the next 10 minutes we’re going to whittle down this castle of confusion and get to the bottom of it. Who are really, the Best Peptide Companies

It is not intended nor implied to be a substitute for professional medical advice. Prior to buying anything, check that it is compliant where you live with your current government laws.

How We Found the Best Peptides Companies

1. Pricing

Listen, the best peptides aren’t cheap. If someone’s selling them for a suspiciously low price, it’s probably a scam. Good quality peptides require a lot of work to make, test, and ship, so expect to pay a decent amount.

2. Payment Methods

This might not seem like a big deal, but it actually matters. Since peptides fall into a bit of a gray area legally, some sellers might only have one or two payment options. But if a company has more options, it can be a sign that they’re legit. Just keep in mind that payment methods can change depending on policies from payment companies.

3. Product selection and TESTS

When it comes to peptides, variety is key. The best companies will have a range of products for different purposes, like building lean muscle, burning fat, or strengthening bones. But don’t just take their word for it – make sure their products are tested by an independent lab.

4. Reviews

If you’re shopping for peptides online, do your homework. Check out reviews from other customers on Reddit or other forums. The more info you have, the better! Don’t rely solely on the company’s website reviews, they might not give you the full story.

5. Our experience ordering

Whenever possible we order products and post unboxing videos, if the product is easy to test and measure we take it ourselvces

Best Peptide Brands

#1 Most Researched Peptide Vendor

#1 Best Tested Peptides: Sports Technology Labs

STL is one of the most trusted research chemical suppliers on the market, and till recently only supplied SARMs. Then, in late 2022, they introduced a line of Peptides as well.

The Peptides have incredibly high quality, something you would come to expect from STL. All their batches are tested before being packaged and sold.

They do stand to increase the Peptides they offer, but I’ll give them time. Their prices are reasonable, especially considering their quality is some of the best there is.

#2 Worldwide Peptide Company

#2 Worldwide Peptides: GenX Peptides

GenX Peptides is certainly the brand least known on the list. Interestingly enough, unlike other brands, they do not claim to be based in the US, but only say they focus on the US market a lot.

They make use of high-performance liquid chromatography-mass spectrometry testing, which sounds great, but it’s not listed anywhere on their site which is a bummer. You could probably email them and ask.

Overall, they offer a decent range of products at reasonable prices. Reviews online are hit-and-miss.

#3 Cheapest Peptide Vendor

#3 Cheapest Peptides: Amino Asylum

Amino Asylum prides themselves on providing the highest quality research products, as they do not just provide Peptides. SARMs, PCT Products, Research Chemicals, and as the name suggests, Amino Acids as well.

With great reviews online, on site and on Reddit, their products hold true to the core value of the company. They might not be the most cost effective in the list, but you’re paying for quality. Just be warned that some individuals have said that the payment process combined with the shipping time can be a bit long.

#4 Peptide Company

#4 Spectre Labs

Spectre Labs is a niche supplier of specific research chemicals – SARMs, Peptides, AIs, etc.

They might not be as well known as others on this list, but they are still really great. Their products are tested by a third company and they have some amazing reviews online.

Another great feature is the fact that they are somewhat affordable. With companies closing down left, right, and center, we will come to appreciate honest companies like these.

#5 Biggest Variety Peptide Company

#5 Largest Variety of Peptides: Pure Rawz

Pure Rawz is a site that just looks the business. And by judging the number of products they sell, they are absolutely just the business. Supplying everything from peptides and SARMs to other research chemicals.

They have a great range of peptides and peptide combinations. The point system they run is something that is always going to be beneficial for saving a few bucks, and the fact that they’re US based, combined with the competitive pricing means they’re really up there in the ranks of great peptide sellers.

#6 Cost-Effective Peptide Company

Cost-Effective Peptides: Limitless Life Nootropics

New kid on the block, and quite a name. Limitless Life Nootropics. The name might sound misleading, but in reality, they do stock quite a few peptides.

They have an enormous range of products, of which quite a few are Nootropics. They also offer fat loss products.

While their peptides might be anything and everything you’ll normally find, their Nootropics are (logically) quite plentiful and are offered at cost-effective prices.

#7 US-Based Peptide Company

US-Based Peptides: Paradigm Peptides

Established in 2014, Paradigm Peptides really focused on supplying high-quality peptides, SARMs, and other research products to their customers. Producing in the States, Paradigm has some mixed reviews online. The reviews on their site are all 5 stars. All of them, barring a select few. This to me is a big red flag, as it’s virtually impossible to perfectly satisfy every single customer.

Offering a wide range of products, ranging from peptides to SARMs, to CBD products as well. They also provide Lab Equipment which is a nice touch. Their UX and UI are pretty good quality, and they have quite a few payment options available.

#9 Highly Specified Peptide Company

Most Specific Peptides: Peptide Sciences

Peptide Sciences is one of the online vendors with the widest range of peptides I have seen. The list is more impressive than your browser history, and the dosing variations of the products are truly remarkable. They’re also really driven to educate people on the different products they have.

They also provide blends of products like this CJC 1295 with the appropriate GHRP-6.  The only real drawback they have as a vendor is a fact that they do not provide any reviews on their website. For that you’ll have to pop over to Reddit, however, when you’re there you will not be disappointed. The anecdotal evidence fits perfectly with their vision of superior-quality peptides.

Best Peptide Company by Country

UK

The UK is known for lax laws compared to other countries (when it comes to these types of products). There are thus a lot of companies to choose from, but the best we can recommend would be Peak Body, or if you don’t mind shipping then definitely Biotech Peptides.

France

France, over in continental Europe, might have specific laws that are everchanging. Thus, before ordering, make sure you read up on the laws first. The best to go with would be Biotech Peptides because of their exceptional quality and prices.

Canada

Canada is also known for having weird laws and regulations. On a good day, you get your shipping. On a bad day, you have to wait. Sports Technology Labs has been known to have good reviews from our friends up North.

Australia (Illegal)

Australia, well, yeah. They’re illegal.

🙅‍♂️ Companies to AVOID

1. Swiss Chems

Unfortunately, Swiss Chems is no longer recommended by us. Since they’ve been in business the quality of other brands has overtaken them with consistent testing, and way better service. SC was a lot more relevant when there was a shortage of alternate brads, but now? Stick to our list. We’ve even been shipped unlabeled bottles – true story.

Four bottles of something came. Two were Glutathione and two were Frag. No labeling, no nothing.

Peptide Companies that Closed

1. Science Bio

Science Bio announced on their website that they will be permanently shutting down on March 31st, 2022. Science Bio was a giant in the research chemical world with numerous products, reviews, and so much more to come. Unfortunately, the company has closed.

2. Proven Peptide

Allegedly, Josh Fulton the owner was sued for trademark infringement and other charges. This brought attention to his businesses selling SARMs, Peptides, etc. Things got heated, and they closed.

Best Peptides for Sale

The obvious question is which ones are best for you? We typically don’t like bullshitting people, so, let’s jump right into it.

  • Fat Loss Peptides include HGH (Illegal), AOD 9604, HGH-Fragment, and Melanotan II (watch out for kidney damage)
  • Muscle Growth Peptides include HGH (Illegal), IGF-1, MGF, and any other that improve your recovery
  • General Health Peptides include HGH (Illegal), IGF-1, Melanotan II, CJC / IPA Blend, Glutathione, and Kisspeptin
  • Sexual Health Peptides include HGH (Illegal), Kisspeptin, and Melanotan II

Keep in mind that peptides do react differently in different people. This includes side effects as well. Always read the peer review science before taking anything.

Peptide Benefits

You drive a Ferrari because you want people to think you can drive fast. You drive a Mustang because you hate crowds. And you drive a Prius because you hate yourself. Every car has a purpose, and so do peptides. There are frankly too many to mention, but they usually fall into 4 main categories: Muscle builders, fat loss accessories, recovery helpers, and then a few random ones doing very niche and specific things.

Category 📚Mechanism 🪓Popular Peptides ⭐
Muscle BuildingIncrease in amount of cells – HyperplasiaGHRP, GHRH
Fat LossLimits lipoprotein lipase (LPL)HGH, HGH Fragment
RecoveryIncreased blood flowTB500, BPC 157
OthersTan, Increased apatiteMelanotan, GHRP-6

Are Peptides Legal?

Peptides may only be sold as research chemicals, and may not be marketed as supplements or for human consumption.

Are Peptides Safe?

It depends. Theoretically, there are no unsafe products. They are only unsafe if you use them wrong. Inject 100 units of Growth in 2 days, yes you’ll most likely end up in ER – so don’t do that. Using 2 units of Growth daily , yes that’s relatively safe.

Can Peptides help for weight loss?

Absolutely. Peptides such as HGH or HGH Fragment can massively aid in weight loss.

How do I know if my Peptides are real?

Check the COA from the Peptide Vendors, and see if you feel/see results. If your BPC 157 isn’t making your injuries feel better, then it might be bunk. It won’t work on your heartbreak after failing that PR though. Those peptides don’t exist yet.

Are Peptides Legal in the US?

Peptides are legally prescribed by many doctors, mostly through HRT and anti aging clinics but you might find that your local doctor who is on the cutting edge prescribe as well. They are also legal to be purchased under the banner of “Research chemicals”, but beware that there are lots of bad actors in this space so choose carefully!

Which Peptides are FDA approved?

While the category of peptide is quite broad, here are some relevant peptides approved for human use.

Insulin, hGH, Somatropin, CJC-1295, Semaglutide (GLP-1), Liraglutide. However this is not a comprehensive list.

Are there any US peptide manufacturers?

Yes, however you’re going to have to stick to prescription compounding for those, most of the research chemical companies are importing from China. No matter what they claim!

Hi. What should I order to burn belly fat (diminish as in lose fat…weight loss AND to build muscle? Also, If I choose to go with the nasal spray option versus injection, how many sprays do I do in each nostril and how many days per week do I spray? Finally, would buying both CJC-1295 & Ipamorelin AND Tesamorelin sprays be a good combo to achieve both belly fat weight loss and building muscle?

Hi. What combo of peptides should I purchase to 1. burn and lose belly fat? and 2? build muscle and increase libido? Also, if I choose to go with nasal spray option versus injections, how many sprays in each nostril and how many days per week do I take the peptides? Finally, would my buying the combo CJC-1295 + Ipamorelin along with Tesamorelin be the right combo to achieve the above results? If so, great. If not, what do you recommend I buy to reach my goals? Thank You!
