OTR-AC is a selective androgen receptor modulator (SARM) that is also commonly referred to as Ostarine-O-Acetate. This compound is an esterified version of the popular SARM, Ostarine, or MK-2866. While Ostarine and OTR-AC elicit similar benefits, the latter is considered to be the stronger of the two compounds following the esterification process.

SARMs YK-11, one of the newest SARMs for sale, acts as a gene-specific agonist of the androgen receptor (AR) in MDA-MB 453 cells. YK 11 works on a variety of different anabolic pathways. YK-11 has shown greater anabolic activity in vitro in C2C12 myoblasts than DHT. YK11 promoted a cascade of muscle growth and key myogenic regulatory factors in skeletal muscle tissue such as myogenic differentiation factor (MyoD), myogenic factor 5 (Myf5), to a significantly greater extent than DHT.

SARMs LGD-4033, also known as Ligandrol, is a 3rd generation non-steroidal oral SARM with a high affinity for the androgen receptor (Ki of ~1 nM). It is currently the second most popular SARM on the market. Unlike testosterone which exerts anabolic effects by the same pathway, LGD-4033 has high selectivity for receptors in skeletal muscle, bone, and connective tissue, with minimal affinity for receptors in the prostate, scalp and skin.

SARMs MK 677, also known as Ibutamoren, Oratrope, or Nutrobal (molecular weight 528.662), is a ghrelin agonist that acts on the pituitary gland as a human growth hormone secretagogue and is sometimes classified along with selective androgen receptor modulators (SARMs). It differs from Ghrelin itself in that it is not a peptide but rather a spiropiperidine. Since it can cross the blood-brain barrier, MK-677 functions as a neuropeptide in the central nervous system. MK 677 Benefits from Clinical Research MK 677 has displayed multiple effects in vivo, including: Increase in GH levels Increase in muscle mass and lean body mass Reduced body fat Increase in bone density Faster muscle growth Improved immune function Improved REM sleep Increased appetite Reversal of growth hormone deficiency Alleviation of pathology related to beta amyloid

synthetic REV-ERB agonist, designed to selectively bind and modulate the REV-ERBα and REV-ERBβ nuclear receptors. It plays a role in circadian rhythm regulation, metabolic pathways, and transcriptional control by influencing gene expression linked to lipid and glucose metabolism.
