Introduction to SARMs
Introduction to SARMs: SARMs is an ancronym for Selective Androgen Receptor Modulators. There are two types of SARMs: steroidal and non-steroidal. While steroidal SARMs have existed for more than 70 years, non-steroidal SARMs are relatively new. They are becoming increasingly popular in bodybuilding circles as a valid alternative to anabolic steroids. As SARMs target only specific androgen receptors, the results are better as the side effect associated with steroid use are very much limited. While scientists research SARMs, at the same time hard-core bodybuilders experiment with them, exploring innovative solutions. And being still under development and tested mostly on animals, there isn’t a comprehensive, final and official medical statement about their effectiveness and the side effects the may produce. All SARMs are selective androgen receptor modulators. Other compounds, which don’t fall into this category such as peptides, are often put in the same group for marketing purposes. They are made solely as performance enhancement products.
The main SARMs available on the market are:
Testolone RAD-140
Cardarine GW-501516
Ligandrol LGD-4033
Ostarine MK-2866
Andarine S4
GTX S-23
YK-11 Myostatin Inhibitor
Nutrobal MK-677
Stenabolic SR-9009
Testolone (RAD-140)
Testolone is considered the most powerful SARM available, even at low doses.
What does Testolone do?
Similar to Methandenone, Testolone provide strength and muscle gains. Experiments have shown that RAD-140 increases lean muscle mass by targeting skeletal tissue androgen receptors. RAD-140 is the most androgenic SARM but is still only 10% as powerful as Testosterone.
Cardarine (GW-501516)
Cardarine is in a class of drugs to treat cardiovascular conditions, obesity, diabetes among other syndromes. This compound is not technically a SARM, but instead is a Peroxisome Proliferator-Activated Receptor Agonist (PPAR). PPARs are not anabolic.
What does Cardarine do?
Cardarine is an alternative to bulking steroids. Cardarine improves massively the overall physical performance of targeted muscle.
Ligandrol (LGD-4033)
Ligandrol is one of the most used SARMs by bodybuilders as it’s one of the most results-tested.
Whate does Ligadrol do?
Ligandrol delivers an increase in lean, quality muscle mass without gains on fat.
Ostarine (MK-2866)
Ostarine is still under developmen and testing as an alternative to treat osteoporosis and muscle wasting.
What does Ostarine do?
Ostarine influence strength and muscle gains and has the most anabolic properties of all SARMs. While it may not be more effective than the most powerful anabolic steroids on the market now, it offers much softer side effects as well.
Andarine (S4)
Andarine is a very popular SARM, even though it is not very strong. It is not researched anymore and results are not clearly determined.
What does Andarine do?
Tests made on animals have shown Andarine being responsible in increasen muscle mass and act against fat.
YK-11
YK-11 is very strong and the most similar to a steroid of all SARMs.
What does YK-11 do?
YK-11 is considered one of the top doping substances to enhance the overall performance of the physique in all sporting activities.
Nutrobal (Ibutamoren/MK-677)
Nutrobal is not a SARM but a ghrelin receptor non-peptide agonist. Like all SARM, it only targets specific areas of the body.
What Nutrobal does?
Nutrobol mymics the stimulation of growth hormone creating a process that increases human growth hormone and insulin-like growth factor 1 (IGF-1), making it effective in mass gains.
Stenabolic (SR-9009)
Stenabolic has shown results on tests on animals involving increased strength and endurance and decreases cholesterol and anxiety levels.
What does Stenabolic do?
Stenabolic provides more endurance, strength and performance, so an user may train longer and also burn fat if on a cutting cycle.
