SARMs, or selective androgen receptor modulators, are used to build lean muscle quickly and effectively. This is done by the SARM targeting only the androgen receptors that are responsible for fat loss and muscle growth in an individual and increasing their efficiency.
Bodybuilders and workout enthusiasts regularly use SARMs to add muscle mass in a safer way than with steroids or testosterone. While they won’t necessarily give as intense results as the unsafe injections, individuals that use SARMs note that the reduction of severe side effects balances everything out.
YK11 is not just a powerful SARM, it is also a myostatin inhibitor and considered as best sarm for size. for Myostatin is a human growth factor in the body that prevents the growth of muscle after a certain point. Therefore, a myostatin inhibitor allows the user to hack their body’s growth mechanisms and continue building up muscle.
History: YK11 was developed and studied initially to potentially treat individuals who had suffered muscle or bone loss due to a disease or cancer.
Benefits: While no scientifically-backed benefits of YK11 have been proven, healthy individuals who have used the SARM compare the rapid muscle building and hardening effects to that of a mild round of steroids. It is also noted to increase the strength of the individual as well as increase their libido.
Side Effects: As with the more potent SARMs, YK11 can cause testosterone suppression by the end of the cycle. This can lead to fatigue, lethargy, and a lack of motivation. Following up with a round of PCT will help the body bounce back and should be done after every SARM cycle. Other noted side effects include joint pain and increased agitation.
Recommended Dosage: It is generally noted that a daily dose of 5 mg to 10 mg is sufficient for muscle growth and fat loss.
LGD4033, also known as Ligandrol, is a research SARM that is one of the most popular and powerful currently available. Some individuals have noted a 10 to 15 pound increase in muscle mass over an 8 to 12 week period.
History: LGD4033 was initially engineered by Ligand Pharmaceuticals, but it is currently being researched by Viking Therapeutics.
Benefits: LGD4033 is one of the best SARMs for bulking up muscle and can easily help to increase lean muscle on an individual during a single cycle of use. Other benefits of using the SARM includes an enhanced recovery time and increased bone density.
Side Effects: One of the most commonly documented side effects is an excess of water retention. Some of the weight that is put on during a cycle tends to end up being water weight. Testosterone suppression and increased stress on the liver are other possible side effects.
Recommended Dosage: The effects and severity of the side effects of LGD4033 are dose-dependent. This causes some individuals to consume a high amount of the SARM and suffer severe reactions. It is advised to stick to the suggested dose of 10 mg to 20 mg a day for up to 12 weeks.
S23 is an investigational selective androgen receptor modulator that was created by modifying another SARM to make it more effective. S23 does not have as much scientific research backing it as some other SARMs do, but the personal accounts from users compare its power with that of LGD4033.
History: Developed by GTx Inc., S23 was created as a possible male contraceptive and is currently still undergoing research.
Benefits: Healthy individuals that have used S23 note that it rapidly increased their muscle mass and provided them with the “hard and dry” muscle look that many bodybuilders crave. Other benefits include an increase in fat loss and increased bone density.
Side Effects: The most common side effects experienced with S23 include increased acne, an increase in aggression, and testosterone suppression.
Recommended Dosage: The standard dosage of S23 is between 10 mg to 25 mg a day. While some individuals claim a lack of side effects at higher dosages, the beneficial effects do not increase with doses higher than 30 mg.
Overall, taking SARMs for size, or bulking, is the primary reason many in the bodybuilding and workout community use the selective androgen receptor modulators. While they can also be beneficial in cutting, or fat loss, it is more common than the initial search for body-enhancing supplements come from wanting to bulk up.
