Question 1

What are SARMs?

Accepted Answer

SARMs (Selective Androgen Receptor Modulators) are a class of non-steroidal research chemicals. They are designed to bind selectively to androgen receptors in specific tissues such as muscle and bone. SARMs are an entirely separate chemical family from anabolic steroids — they do not share the same molecular structure, origin, or mechanism of action. They are sold exclusively as research chemicals and are not intended for human consumption.

Question 2

Are SARMs the same as anabolic steroids?

Accepted Answer

No — not at all. SARMs and anabolic steroids are completely different compounds. Steroids have a steroidal (four-ring carbon) chemical structure derived from the cholesterol backbone. SARMs are non-steroidal synthetic molecules with an entirely different chemical structure. The only thing they have in common is that both can interact with androgen receptors — but how they do so, how they are metabolised, and their chemical identity are completely different. At Testosterone Muscle, SARMs and steroids are separate product categories.

Question 3

Are SARMs lab tested?

Accepted Answer

Yes. Every batch of our SARMs is tested by an independent third-party laboratory for identity and purity. Certificates of Analysis (COA) are available on request via info@testoteronemuscle.nl with your order number.

Question 4

What is a COA (Certificate of Analysis)?

Accepted Answer

A Certificate of Analysis is an official document issued by an independent laboratory confirming the exact identity and purity of a compound. It proves what substance is in the product and at what concentration. You can request a COA for any SARMs product by emailing info@testoteronemuscle.nl with your order or product name.

Question 5

Are SARMs legal in the Netherlands?

Accepted Answer

SARMs sold by Testosterone Muscle are research chemicals, not medicines or supplements. The legal status of SARMs varies by country and jurisdiction. It is entirely your own responsibility to know and comply with the laws applicable in your region. We sell exclusively to adults aged 21 and over who purchase on their own initiative and responsibility.

Question 6

What does "research chemical" mean for SARMs?

Accepted Answer

A research chemical is a substance used for scientific and analytical research. SARMs are sold as research chemicals because they have not been approved as medicines or dietary supplements by any regulatory authority (such as EMA or FDA). They are not intended for human consumption. Our products are sold solely for laboratory research purposes.

Question 7

How should SARMs be stored and what is their shelf life?

Accepted Answer

Store SARMs in a cool, dry, dark environment away from direct sunlight and moisture. Keep them away from heat sources and do not store in a bathroom. When stored correctly, shelf life is typically 2 years from the production date. The best-before date and batch number are printed on every label.

Question 8

Why does Testosterone Muscle sell capsules instead of liquid SARMs?

Accepted Answer

Testosterone Muscle sells exclusively capsule-form SARMs. Capsules contain a precisely pre-measured amount per unit, making them straightforward to handle in a research context — unlike liquids, which require accurate pipettes or droppers and are more susceptible to measurement error, oxidation, and degradation over time.

Question 9

Are Testosterone Muscle SARMs the same quality as black-market products?

Accepted Answer

No — there is no comparison. Black-market SARMs are routinely found to be mislabelled, underdosed, overdosed, or contaminated with unknown substances including prohormones or actual steroids. Testosterone Muscle sources exclusively from verified manufacturers and every batch is independently lab-tested before being listed for sale. Batch-specific COAs are available on request.

Question 10

What are anabolic steroids?

Accepted Answer

Anabolic steroids are synthetic compounds built on a steroidal four-ring carbon (cyclopentanoperhydrophenanthrene) backbone — the same structural base as naturally occurring hormones such as testosterone and oestrogen. They are a completely separate chemical family from SARMs. All steroid compounds sold by Testosterone Muscle are research chemicals, not medicines, not supplements, and are not intended for human consumption.
