best peptides 2022

Peptides have become all the rave in the past couple of years, and for good reason. Using these Amino Acids for research purposes has been shown to have multiple potential benefits and if you use top quality Peptides you’re pretty safe as well.

Let’s look at the 5 Best Peptide Companies on the market today, comparing lab-verified results, shipping costs, and everything in between.

Key Takeaways

  • The best Peptide company you can purchase from would be Biotech Peptides
  • Other great companies include Amino Asylum, Sports Technology Labs, and Pure Rawz
  • Most Peptides have very few side effects, but some do

Who is the Best Peptide Company?

When looking to find the best Peptide company, there is an awful lot to consider – more on this later. And all things considered, the best Peptide vendor would have the be Core Peptides.

Core Peptides has been one of the leading Peptide suppliers for quite some time, providing a wide range of premium Peptides that are tested for quality.

One other key feature is that the Peptides are lyophilized in the USA. This is something that isn’t incredibly common with different Peptide companies, thus, it makes Core a valuable vendor.

How We Chose the Best Peptide Vendor

As mentioned, there are multiple things to consider when choosing the best brands. Online Peptides can be a tricky business, and just focusing on who has the cheapest product is sure to get you in trouble.

  1. Quality Products

You have to make sure the research chemicals like Peptides you are buying are actually made to a high standard. Again, these products are not regulated by anyone so you are at the mercy of whoever your supplier is.

The best thing you can do is look for up-to-date third-party testing, and testing that is done by a real company! You could also Google to find out what you’re supposed to experience while using these Peptides. Use that to gauge whether or not a company’s product is good.

  1. Good Reviews

Unfortunately, it has become very easy to fake any Mass Spectrometry test results. Sure, you can contact this third party, and you should, but you’re also supposed to look at what other users have experienced with this company.

The easiest place to do this is through Reddit. Find other people who have used the Peptide vendor you are interested in – ask questions and see what people say about Peptide sources before you buy them.

  1. Great Customer Support

I’ll be the first to admit that Peptides are hard to understand. Proper storage, dissolving them, powder form vs oral, and just what exactly they do is all incredibly confusing.

A good vendor should be able to tell you something about the Peptide in question, perhaps not as much as a healthcare provider, but they should tell you something!

They should also be great with responses, fast, effective, and helpful.

  1. Pricing

Peptides can sometimes get pricey. Buying Peptides online can get really pricey. You have to compare dosages and do a bit of math to find out which supplier will have the best-priced Peptides.

Also, if something is too cheap, it is usually a flunk…

#1 Leading Peptide Supplier

Core Peptides

Core Peptides might be a young, up-and-coming brand but they have plenty to offer. From a wide range of peptides to decent pricing and even testing on most of their products.

Core Peptides will have almost any peptide you’re looking for, and the customer support is good enough to return your communications to discuss their plans for the future.

Great shipping and payment options makes them a real contender for being the best on the market.


  • Extensive range of products available
  • Great prices
  • Testing on some of the products


  • Could stand to test all of their products
#2 Excellent Peptide Supplier

Biotech Peptides

Biotech has been around now for a while and has come to be one of the most trusted suppliers you can come by. Most of their peptides have a COA and their range is staggering.

Unfortunately, they only offer peptides, but that’s a good thing since they clearly have a focus. Biotech also has excellent reviews online along with great shipping and payment options.

If you want genuine peptides worth the cash – Biotech Peptides is the place to be.


  • Massive range of products available
  • Reasonable prices
  • Testing on some of the products


  • Could stand to test all of their products
#3 Most Tested Peptide Supplier

Sports Technology Labs

Sports Technology Labs or STL for short is a new company that started off only producing SARMs. They were at the forefront of SARM vendors due to their religious testing of every single batch.

This dedication to testing stuck around when they started producing Peptides recently. Every batch is tested, making Peptides safe.

Their range is lacking, however, and I’m sure in the years to come they will expand greatly. They offer good payment methods, but because of all the testing, they are a bit more expensive than other suppliers.


  • Decent range of products available
  • Also offers SARMs
  • Testing on each and every product


  • Quite pricey
  • Other companies have slightly more products
#4 Affordable Peptide Supplier

Amino Asylum

Amino Asylum is certainly more well-known than the others on this list, and for good reason. Not only do they have a massive range of Peptides online, but they also offer SARMs, PCT supplements, and various other therapeutic compounds.

They do not offer testing. This is the biggest drawback of Amino Asylum, and while some may argue that their affordable pricing makes this worth it, these are research Peptides after all.

You are using something (sometimes) that has not been approved for human consumption, so personally, I would pay more for high-quality Peptides that have been tested.

That said, in a pinch, Amino Asylum is still one of the best.


  • Massive range of products available
  • Also offers SARMs and other products
  • Cheap


  • Testing could be improved a lot
#5 Widest Range of Products

Pure Rawz

If you’re looking for a vendor to supply Peptides, SARMs, and any other research chemicals your might want or need, chances are Pure Rawz has it.

Pure Rawz has been a giant in this market for years, and they probably have more clients than you could imagine. As far as Peptide vendors go, they’re okay. Unfortunately, they do not offer testing which makes them rather affordable.

It would be nice to see some high-performance liquid chromatography in their listings, but their Peptide sciences have made a lot of clients happy according to reviews.


  • Massive range of products available
  • Offers more products than anyone else
  • Somewhat affordable


  • Testing could be improved a ton

What are Peptides? 

Peptides are simply chains of Amino Acids bound by peptide bonds – hence the name. Peptides can be synthesized with a specific sequence of Amino Acids and said sequence will dictate what the effect of said Peptides are.

There are numerous Peptides you can find online, and many of these were originally developed to treat certain illnesses in the medical world.

The most common Peptide of all is Human Growth Hormone or HGH. HGH is naturally produced by the body, but levels begin to drop as we age.

Doctors soon noticed that HGH not only has certain health benefits but also certain anti-aging properties. Metabolic research is still ongoing on certain Peptides, but the healthcare industry is incredibly keen on using more Peptides in physical therapy.

How Do Peptides Work? 

As mentioned, Peptides will differ greatly from one another based on their individual Amino Acid sequence.

While many exogenous hormones can have severe side effects, not all Peptides are hormones as such, and therefore have far fewer side effects.

There are Peptides for every ailment you might imagine. Some aid in muscle growth, some aid the cell cycle regulation, while some will literally burn fat faster than any other obesity drug could.

Benefits of Peptides

Since there are several different Peptides, I am going to list some of the more common ones.

  • HGH and HGH Fragment can aid in fat loss, skin health, hair growth, and Anti-Aging
  • IGF-1 can aid in improving total bodily function, and increase muscle growth and bone mass
  • PT-141 can increase sexual function in men
  • GHRPs and GHRHs are known for having Anti-Aging effects
  • Some newer Peptides can even improve cognitive function

Side Effects of Peptides

Since there are several different Peptides, I am going to list some of the more common ones.

  • All Peptides that increase HGH can lead to insulin resistance
  • Melanotan II can have a negative impact on your kidneys
  • Most other Peptides usually upset your stomach slightly, but not a lot

Certain Peptides are already approved for treatment by the FDA, while other Peptides may only be sold as ‘research Peptides’ and ‘not for human consumption’.

Results of Peptides

On the effects of PT-141, a Reddit user had the following to say

“I have used a combination of PT-141 and 50mg Cialis and had an on/off erection for 3 days.

Had the most amazing sex session that lasted a few hours.

I also suffer from ED due to secondary hypogonadism. I think it depends on where you get the PT-141 from and also dosage – I used 2mg.

PT-141 was first discovered when scientist Mac Hadley’s generous volunteered of himself to inject a double dosage of MT2 and ended up with an 8hr erection.

Currently, Bremelanotide PT-141 is administered via a subcutaneous injection, ideally where there are fat deposits. The only legitimate form of the peptide is injectable. Oral pills, nasal sprays, and creams have not been shown to be an effective means in which to administer Bremelanotide PT-141 (so avoid creams and nasal sprays).”

On the topic of HGH Frag, another Reddit user had this to say

“***Below is merely recap of my results, I do not condone the use of PEDs and this is not medical advice. This is just me rambling and it should not be used as guidance or advice***

TLDR Summary:

  • Ran Frag 176-191 for 3.5 weeks, upping the dose each week. AM/PM doses with fasting periods before/after doses. Zero sides effects, zero “feeling it working”, felt the same except weight kept dropping and dropping.
  • Lost 7lbs in 3 weeks after upping my cals and slacking on diet, how much of that was fat and how much was water/glycogen stores dropping from coming off cycle I have no idea, you be the judge.
  • Some of the weight loss was for sure attributed to glycogen/nitrogen dropping from going back to TRT dose. I would run this while on cycle going forward for best visible results, since you will retain your muscle size/hardness from the AAS and can be more aggressive with diet without risking muscle catabolism.”

Forms of Peptides

Peptides will come in various forms, from tablet form to injectable. Some Peptides can even be found in Nasal Spray form, each with their own drawbacks and benefits.

Conclusion: Best Vendor for Peptides 

Choosing the Peptide companies is a lot harder than you might think. There are a lot of factors to consider, but we have narrowed it down to the list above as the best places to buy Peptides.

When making a purchase, look for the highest purity and a decent price. Consider things like worldwide shipping, if the Peptide shop offers testing, and how they compare to other Peptide vendors.


Peptides can be bought under the nomenclature of ‘not for human consumption’ and ‘research Peptides or Chemicals’.

Which Peptides are worth the money?

The ones that work the best would have to be HGH and HGH-boosting compounds.

Are Peptides safe?

For the most part, yes. However, you have to do research on the particular Peptide you intend on buying before using it to be safe.
