Ostarine, also known by its code names MK-2866, Enobosarm, and GTx-024, is a Selective Androgen Receptor Modulator (SARM) developed for medical purposes. Initially, it was designed to treat conditions like muscle wasting diseases and osteoporosis. Unlike traditional steroids, Ostarine works by selectively targeting androgen receptors in muscle and bone tissues, promoting muscle growth and bone…

YK11, chemically known as [(17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester], is a synthetic selective androgen receptor modulator (SARM) that has gained attention for its potential in promoting muscle growth and bone density. Unlike traditional anabolic-androgenic steroids (AAS), YK11’s mechanism of action involves: Selective modulation of androgen receptors Inhibition of myostatin, a protein that inhibits muscle growth YK11…

Testolone, commonly referred to by its chemical name RAD 140, is a type of Selective Androgen Receptor Modulator (SARM) that has garnered attention for its potential to enhance muscle strength and overall physical performance. Initially developed as a potential treatment for conditions like muscle wasting associated with cancer (cancer cachexia), sarcopenia, and osteoporosis, RAD 140…

Stenabolic, also known as SR9009, is a research chemical that has gained attention in both scientific and fitness communities. It acts as a Metabolic Modulator by interacting with a specific core clock component known as REV-ERB. This interaction influences various biological processes, including fat metabolism, muscle function, and circadian rhythms. Originally developed by Professor Thomas…

LGD-4033, commonly known as Ligandrol, is a type of Selective Androgen Receptor Modulator (SARM) that has gained significant attention in both the medical field and among athletes. This chemical compound is designed to mimic the activity of testosterone, specifically targeting androgen receptors in the body. Its primary appeal lies in its potential to enhance muscle…

MK-677, also known by its chemical names such as MK 677, Ibutamoren, MK-0677, LUM-201, L-163,191, and its brand name Oratrope, is a potent growth hormone secretagogue. This compound has garnered significant attention due to its ability to stimulate the production and secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) without significantly affecting…

Selective Androgen Receptor Modulators (SARMs) are a class of therapeutic compounds with properties similar to anabolic steroids but with reduced androgenic (producing male characteristics) properties. SARMs, such as Ostarine (MK-2866), Ligandrol (LGD-4033), Andarine (S4), and Cardarine (GW-501516), target androgen receptors in muscle and bone tissues specifically, promoting anabolic activity (muscle growth) without the broad side…

Selective Androgen Receptor Modulators (SARMs) have rapidly gained popularity in both fitness and medical communities due to their unique properties. Unlike anabolic steroids, SARMs are a class of compounds specifically designed to target androgen receptors in muscle and bone tissues, promoting tissue growth with fewer side effects. This specificity has made SARMs a subject of…
