This American company delivers top-quality, pure SARMs at reasonable prices. The company offers worldwide services, however, there is a shipping cost.

Second, on our list is Chemyo. Although this company is based in the USA, they offer worldwide delivery services. What’s more, their delivery time is pretty decent, even for non-US citizens.

3. Swiss Chems

Last on our list is Swiss Chems, truly a force to be reckoned with!

When it comes to using SARMs for muscle gain, the purity of the product is what matters, or else the results won’t be as prominent. Not only that but using compounds that aren’t pure can lead to dangerous side effects which can ultimately cause serious medical conditions.

Why choose Swiss Chems?

Apart from the previously mentioned facts, there are a few more reasons why you should consider buying your SARMs from Swiss Chems.

Ultimately, what sets them apart from other companies is the fact that they test all of their products in a lab, and they publish the results for everyone to see! As we all know, most companies don’t disclose that type of information, which makes it difficult to recognize whether their product is worth buying. What’s more, it’s this type of transparency that guarantees they’re invested in what they’re selling.

They’re testing policy is strict, and it requires that they test all of their raw ingredients for FTIR/HPLC/GC-MS/LC-MS. Moreover, they’re also required to undergo Nuclear Magnetic Resonance Spectroscopy testing that’s conducted by both their very own experts and other labs.

Every test they do on their compounds allows them to properly dose their supplements which helps their users experience the benefits in record time. Users require small doses to start noticing great results. Other suppliers aren’t as generous with their products, meaning you’ll need to consume higher doses of SARMs over a longer period of time in order to get the same results.

What’s more, we can safely say that the company keeps its dosages consistent, which ultimately makes it possible for your body to react the same way each time you’re on a cycle. Basically, your muscle growth and strength are enhanced, as your body fat decreases at a satisfyingly fast rate.

SARMs, or Selective Androgen Receptor Modulators, are therapeutic compounds with little to no androgenic properties. They were, in fact, present way back in the 1940s when steroidal SARMs were used for medical purposes.

There are several different types of SARMs, but four of these types are especially popular with athletes and bodybuilders:

  1. LGD-4033 — used for reducing body fat and enhancing lean muscle mass
  2. Andarine — used for bone tissue and to help cure osteoporosis
  3. Ostarine — great for maintaining and increasing lean body mass
  4. RAD140 — used for muscle building
