Finding a reputable source for SARMs can be frustrating. First, there are hundreds of different sources to choose from. It is hard to tell who is legit and who is not. You also have to deal with alternative payment options for a lot of sources.

For a long time we have been looking for the number one SARMs Source on the internet. Have we found it finally? Here is our full Proven Peptides Review.

History of Proven Peptides

Proven Peptides has been around for a very long time. They originally started selling SARMs online in 2013. In an industry crowded with sources that just want to make a quick buck, it is good to find someone who has been around for multiple years.

Their company has sold millions of dollars worth of SARMs and peptides over the years. They have a very detailed track record of customers.

Legit or Bunk?

The most important thing to consider when buying SARMs online is whether your source is legit. Undoubtedly, Proven Peptides is legit. You can find logs on Reddit and other bodybuilding forms that show some impressive before and after results from using Proven Peptides’s products.

Is anecdotal evidence isn’t sufficient for you then you’re not alone. Luckily for you, we lab-tested a few of their SARMs and they all came out with over 98% purity. This is the biggest factor in our Proven Peptides review. We only give a source a high rating if their products are proven to be pure.

Our lab tests also show that the products provided were free of dangerous prohormones and steroids (we test for 12 different contaminants).

Here is another SARMs user who lab tested some products from Proven Peptides as well. He confirmed that the results were positive:

Lab Test Results

As with many other SARMs sellers, PP uses Colemaric Analytical to conduct their 3rd party lab testing. The big advantage here comes with just how often they update their lab test results. Just take a look at how often they publish their lab tests:

Lab tests are published bi-weekly on the Proven Peptides “why us” page

There are even more that aren’t shown in the screenshot above dating back to 2018. It’s pretty remarkable and it shows that the owners are committed to providing quality products. Here’s a more detailed look at one of the lab testing reports for their MK 677:

Colemaric is well known in the SARMs space for being a decent lab and they do testing for many other companies in this space as well. You can rest assured that they are a real lab and that Proven Peptides does in fact use them to test their products.

Available SARMs

Proven Peptides has a lot of different products to offer. Here are just a few of them:

They are constantly adding more products to their inventory. As new SARMs get brought to the market, their inventory expands to compensate. From what we see, they are usually the first company to add new SARMs to their lineup.

How to Calculate Dosage

Many customers ask us in the comments how to dose the products they buy. They make it very easy. When you purchase from their site, you will see a few different size options to choose from:

proven peptides bottle sizes
Different doses available for sale on the website

What size you choose depends on how long you want to run your cycle for and at what dosage. If you scroll down on the product page, you will see the concentration listed:

proven peptides ostarine concentration

For this example, we are using Ostarine, but all products will have their concentration listed in the description. As you can see, they make their Ostarine with a 25mg/ml concentration. Here are some example cycles to show how to calculate what bottle size you need:

Cycle:25mg a day for 6 weeks12.5mg a day for 8 weeks
Total MG needed:1050mg700mg
Bottle size needed:60ml30ml

To do your own calculation, use the following formula:

(Daily Dosage) x 7 x (Number of Weeks) = Total MG needed

  • 15ml bottles of Ostarine from PP contain 375mg total
  • 30ml bottle = 750mg total
  • 60ml bottle = 1,500mg total

Customer Service

Proven Peptides is one of the few SARMs companies out there that has a real customer service team. Most companies that sell SARMs only use email support.

When you shop with them, you will be happy to know that they have a dedicated phone support line along with email and ticket support. Out of all the sources we have looked at, nobody comes close to matching the customer service they provide.

It’s a nice touch to be able to call the source you are dealing with. We hope that other companies will follow suit.

As you can see, everyone using these products are getting results.

Proven Peptides Coupon Codes

Proven Peptides has a lot of coupons and discount codes available for use. These offers are typically sent out via email, so you will need to register on their website for the newsletter.

We have seen the average discount code for proven peptides range from 15% to 25% off.

They also have a spin the wheel feature on their website. When you stay on their website for a few seconds, you will see this screen pop up:

The wheel spinning game offers multiple coupon codes for Proven Peptides.

Peptide Points

One of the best reasons to choose this source is their customer loyalty program known as Peptide Points. When you purchase from their store, you are automatically enrolled into the rewards program. You get a point for every dollar that you spend, and points can be redeemed for discounts off your next purchase.

We were able to score free bottle simply by making a normal purchase with them. There are a few other SARMs companies that offer rewards programs, but this one seems to be the most generous with an actual value.

We would estimate that the peptide points reward system equates to around 15% off depending on how you spend.

Shipping Times

Every time we have ordered, the shipping times have been lightning fast. It is not uncommon to receive in order from them in 2 to 3 days. They are based in the United States, so if you live in America, this is one of the best sources to deal with.

Dealing with a domestic source means you do not have to worry about customs checking your order or your package getting seized. Another benefit of ordering from an American source is that you have a return policy in place.

Last, the shipping prices are cheap. Most orders will qualify for free shipping. This is especially true if you’re buying a whole stack of SARMs and have multiple bottles on the way.

Final Proven Peptides Review

Out of all the SARMs sources currently available, we STRONGLY recommend Proven Peptides. Our lab tests show that their products are legit, and they have the best customer service in the industry.

When people ask me about other sources, I always wonder to myself: “Why bother when PP is open for business? There’s no reason to even look elsewhere”. It’s so true and still is. As long as they continue to live up to their name, I will continue to recommend them.
