For several years now, you’ve been hearing and reading about SARMs. Therefore, we would like to educate you here about selective androgen receptor modulators and clarify the following questions:

  1. What are SARMs?
  2. How do SARMs work? And do SARMs actually have side effects
  3. What are the advantages over steroids, prohormones & Co.
  4. What SARMs are there?
  5. Are SARMs legal?
  6. Where can I buy SARMs?

Note: This blog post is intended only to inform about SARMs, because the trade, purchase and use of these substances is regulated in some countries – including Germany. We would like to inform here, but not to encourage or instruct consumption.

What are SARMs?

First of all, what are SARMs? As mentioned earlier, SARM is the abbreviation for selective androgen receptor modulator. Bulky word construct, right! But it means nothing more than that a modulator acts selectively – explicitly and exclusively – at the androgen receptor.

The binding ability to the androgen receptor of SARMs is even higher than that of testosterone (by up to tenfold, according to studies). So they have a similar effect to anabolic and androgenic steroids with fewer side effects; but more on that later.

SARMs: potential drugs with powerful effects

Actually, SARMs were developed in the 1990s specifically for medical use, but are increasingly used in bodybuilding and other athletes. Indeed, early tests showed super results in terms of muscle growth, fat loss, and the counteracting of prostate overgrowth, which is common when taking other substances. Selective androgen receptor modulators have been identified as promising drugs that may have very specific applications in various diseases (e.g., muscle wasting and other muscle diseases, osteoporosis, obesity, etc.). Thus, these are potential drugs, some of which are currently still being researched or are already in clinical trial phases. The best known and currently best researched SARMs are Ostarine and Andarine.

How do SARMs work?

SARMs act similar to anabolic and androgenic steroids and quite quickly. Users experience great gains in strength as well as lean muscle mass – that is, without fat and water retention. Because some SARMs also activate an enzyme called AMKP (AMP-activated protein kinase), the body is stimulated to provide energy and accelerate fat burning. The regeneration is also accelerated. Since androgens are also involved in bone metabolism and prevent the breakdown of bone substance, SARMs can also provide good services here.

Effect of SARMs at a glance:

  • Rapid gains in lean muscle mass
  • increased strength
  • no water retention
  • more energy
  • boosted fat burning
  • improved recovery
  • protection of bone substance, increased bone metabolism

Side effects of SARMs

Since selective androgen receptor modulators only act at the androgen receptor, they have no or hardly any side effects. In addition, SARMs are not steroid hormones and are also not perceived by the body as hormones, which is why no conversion to estrogen (aromatase) occurs. At the same time, studies have shown that SARMS act mainly in anabolic tissues such as muscles. Androgenic tissue, such as the prostate, is much less affected. Therefore, the increase in organ or prostate size, if any, is minimal. There is also no liver toxic effect.

SARMs versus steroids, prohormones & co.: Which is better?

The biggest advantage of SARMs over anabolic steroids, prohormones and co. is that they have significantly less or no side effects. As explained, they act selectively and thus do not affect the prostate, hormone levels and so on. Most users also advocate that SARMs are orally available. So you can take the active ingredient in capsule or tablet form and don’t have to regularly inject / inject it into your muscles or subcutaneous fat. While steroids also suppress the concentration of LH (luteinizing hormone) and FSH (follicle stimulating hormone) – which can lead to infertility – SARMs generally don’t (only at massively high doses).

SARMs are considered the safer alternative to steroids, prohormones and co. because they achieve similar results in terms of muscle building and fat reduction, but have no side effects..

Are SARMs legal?

Caution: We may and can not make any legally binding statements, but want to show you the legal situation known to us (as of April 2021) in the following. Please always inform yourself about the respective legal situation in your country before buying and consuming SARMs.

There are countries where SARMs are legal and may be produced and traded there.

Until 2018, SARMs were legal in the U.S. as well, to the extent that there were simply no precise regulations. So the SARMs declared as “research chemicals” could be legally sold, bought and consumed. In 2019, the U.S. government enacted the SARMs Control Act. Meanwhile, they belong to the same category as opiates, cocaine or anabolic steroids, which is why possession, sale, but also consumption is punishable in the United States.

Are SARMs legal in Germany?

But what is the legal situation in Germany? Although SARMs are very popular in Germany, they are only legal under certain conditions for amateur athletes.

Selective androgen receptor modulators namely fall under section 2 of the Anti-Doping Act (AntiDopG §2 of Dec. 10, 2015.

According to this law, it is forbidden to use a SARM or any other doping substance in Germany:

to trade with it
to sell, dispense or otherwise place it on the market without trading in it
to prescribe
use it on another person for the purpose of doping in sport
to acquire, possess or use it in a quantity not insignificant for the purpose of doping humans in sport …

In addition, Section 3 AntiDopG states: It is prohibited to use or have used a doping agent […] on oneself without medical indication with the intention of gaining an advantage in a competition of organized sport. The prohibition does not apply if the doping substance is used outside a competition of organized sport and the doping substance is or contains a substance prohibited by Annex I of the International Convention against Doping only in competition.

Now you’re probably wondering what all that even means. First of all, it means that as an amateur athlete, you are allowed to possess and take SARMs for personal use in small quantities – as long as they do not come from illegal sources. But what is a “small quantity” now? According to the Doping Substances Quantity Ordinance (DmMV), the small quantity for SARMs is a maximum of 90 mg. Since many supplements have a dosage of 10 to 20 mg, you may therefore have about four and a half to nine daily servings.

But be careful: If you participate or plan to participate in organized athletic competitions, it is prohibited to possess or consume the substances, which include selective androgen receptor modulators.

SARMs in competitions

If you are wondering whether you are allowed to use SARMs in competitions, we have a clear answer for you: No. As described earlier, you may not use SARMs to give yourself an advantage in athletic competitions – no matter how tempting it sounds.

Since 1998, the World Anti-Doping Agency (WADA) has had SARMs on the banned list within the “other anabolic substances” subgroup. And since 2013, this, as well as the 90 mg limit, has also been enshrined in law in the Doping Substances Quantities Regulation. SARMs have already been detectable in doping tests for many years, which is why we advise you against any attempt to abuse them. Doping tests use chromatographic and mass spectrometric systems to detect the banned substance using urine. Unfortunately, however, there are always more or less prominent athletes who try it and then have to reckon with the sometimes considerable consequences.


Unfortunately, SARMs are often made in illegal labs or by private individuals using cheap drugs from China because the production of SARMs is banned in many countries. So if you want to buy SARMs, please look carefully where and what you purchase.

However, there are some manufacturers that offer high quality SARM supplements that we want to point out the ones here:

In our online store for dietary supplements and sports supplements you can exclusively buy high-quality SARM supplements from reputable manufacturers. If you have any questions about selective androgen receptor modulators or our products, feel free to contact us!
