Generic Name : Mesterolone Mesterolone is a synthetic anabolic-androgenic steroid (AAS) and derivative of dihydrotestosterone (DHT). It is inactivated by 3α-hydroxysteroid dehydrogenase in skeleta muscules so it is considered a weak androgen. It is not a substrate for aromatase so it is not converted into estrogen. Mesterolone demonstrated to have minimal effect on sperm counts and levels of FSH or LH 1,2. Experiments of mesterolone serving as a potential treatment of depression are still undergoing. Male Hypogonadism/Androgen Deficiency: The primary medical use is to treat low testosterone levels in men due to hypogonadism (a condition where the testes produce little or no hormones). This helps restore normal sexual function, mood, and energy levels. Male Infertility: It is used to manage male infertility that stems from low androgen levels, as it can improve sperm count and quality in affected men. INN: Mesterolone CAS No.: 1424-00-6 Molecular formula: C₂₀H₃₂O₂ Molecular weight: ~304.47 g/mol Assay (Potency) Typically 98.0% – 102.0% (on anhydrous basis), depending on pharmacopeial or internal standard

Oxymetholone raw active pharmaceutical ingredient (API) is used to produce medications for various medical conditions, primarily anemias and muscle-wasting syndromes, as well as for illicit performance enhancement in sports. INN: Oxymetholone CAS No.: 434-07-1 Molecular formula: C₂₁H₃₂O₃ Molecular weight: ~332.48 g/mol White to off-white crystalline powder Practically insoluble in water; soluble in certain organic solvents USES : Bodybuilding, muscle enhancement, or performance enhancement Cosmetic or recreational use Oxymetholone binds to androgen receptors inside target cells (e.g., bone marrow, muscle). The drug–receptor complex moves into the cell nucleus. There, it binds to specific DNA sequences (androgen response elements), changing gene expression.

Stanozolol is used to treat hereditary angioedema. Stanozolol is one of the AAS commonly used as performance-enhancing drugs and is banned from use in sports competition. It is an anabolic steroid that is known to have a diuretic effect. Stanozolol has been used with some success to treat venous insufficiency. It stimulates blood fibrinolysis and has been evaluated for the treatment of the more advanced skin changes in venous disease such as lipodermatosclerosis. Several randomized trials noted improvement in the area of lipodermatosclerosis, reduced skin thickness, and possibly faster ulcer healing rates with stanozolol. It is also being studied to treat hereditary angioedema, osteoporosis, and skeletal muscle injury. Stanozolol is used for physique- and performance-enhancing purposes by competitive athletes, bodybuilders, and powerlifters.

Drostanolone Enanthate powder is used to produce injectable drostanolone, an anabolic steroid known for enhancing muscle density, strength, and fat loss. It is favored by bodybuilders for its ability to promote a lean, defined physique, with minimal water retention. Drostanolone enanthate (also known as dromostanolone enanthate or its former brand name, Masteron Enanthate) is a synthetic, injectable anabolic-androgenic steroid (AAS) that is derived from dihydrotestosterone (DHT). It is not a pharmaceutical drug that has been approved for medical use, unlike its propionate ester version. Key Characteristics and Uses Chemical Basis: It is an ester of the active hormone drostanolone, with the enanthate ester attached to prolong its action in the body after intramuscular injection. This contrasts with the faster-acting propionate version. Medical Context: The related drostanolone propionate was historically used to treat advanced, inoperable breast cancer in postmenopausal women due to its anti-estrogenic effects. Non-Medical (Illicit) Use: Today, drostanolone enanthate is primarily used illicitly by athletes and bodybuilders for physique- and performance-enhancing purposes. It is particularly popular during “cutting cycles“ as it helps to promote muscle function, definition, and fat loss while retaining strength. Mechanism of Action in Bodybuilding: As a DHT derivative, it does not aromatize into estrogen, meaning it does not cause estrogen-related side effects like gynecomastia or significant water retention. It also works as an anti-aromatase agent, synergistically reducing the effects of other aromatizing steroids like testosterone.

Name: Drostanolone Propionate Chemical class: Anabolic–androgenic steroid (AAS), DHT derivative CAS Number: 521-12-0 Molecular Formula: C₂₃H₃₆O₃ Molecular Weight: ~360.53 g/mol Description: Propionate ester of drostanolone (short-acting ester) Drostanolone propionate is an anabolic–androgenic steroid (AAS) and a derivative of dihydrotestosterone (DHT). Appearance White to off-white crystalline powder Odorless or nearly odorless Practically insoluble in water Soluble in organic solvents (e.g., ethanol, acetone, oils) Drostanolone Propionate RAW (API) is a regulated steroid raw material with defined identity, purity, and quality attributes. Drostanolone propionate is a DHT-derived anabolic–androgenic steroid (AAS). The propionate ester only affects release rate; the active hormone is drostanolone. After administration in historical medical or research contexts, esterases cleave the propionate ester This releases free drostanolone into circulation The propionate ester provides a relatively short duration of action
