Description

Methasterone 20mg (100 Tablets) ZPHC

Methasterone is a synthetic oral anabolic compound of the 17α-alkylated class, derived from dihydrotestosterone . This compound is characterized by a 2α-methyl and a 17α-methyl substitution on the 5α-androstane skeleton, a modification that confers high oral bioavailability and a distinct metabolic profile . Methasterone, also known as methyldrostanolone, is classified as a Schedule III controlled substance in the United States and is included on the World Anti-Doping Agency (WADA) Prohibited List . This product is intended for use as a certified reference material for analytical and forensic applications.

This Methasterone 2000mg Kit from ZPHC provides 100 hermetically sealed tablets, each containing 20mg of the compound, for a total of 2000mg. The product is manufactured under strict quality-control standards, and each kit includes a security hologram, batch number, and validation code to confirm its authenticity. This product is for professional use only and is not intended for human consumption.

Frequently Asked Questions

Q1: What is Methasterone and what is its chemical classification?

Methasterone is a synthetic, orally active 17α-alkylated anabolic-androgenic steroid (AAS). Its chemical name is 2α,17α-dimethyl-17β-hydroxy-5α-androstan-3-one . It is a derivative of dihydrotestosterone (DHT) . It is classified as a Schedule III controlled substance and is included on the World Anti-Doping Agency (WADA) Prohibited List .

Q2: What are the primary applications of this Methasterone product?

This product is designed for use as a certified reference material (CRM) for analytical testing and forensic toxicology, particularly in WADA-accredited doping control laboratories. Its unique metabolic profile makes it useful for validating analytical methods such as GC-Orbitrap-HRMS .

Q3: How is the authenticity of this ZPHC product verified?

ZPHC provides an anti-counterfeiting verification system . Each product package includes a security hologram and a unique validation code. The authenticity of the product can be confirmed by entering this code on the official ZPHC verification platform . It is important to note that third-party sellers may not be legitimate, and the official domain for product authentication is zphc.com .

Q4: What are the storage requirements for this product?

Store the product in a sealed, cool, and dry condition . Follow the storage recommendations provided on the product data sheet .

Q5: What are the known risks associated with anabolic steroid use?

Anabolic steroids are associated with serious health risks. Potential side effects include liver damage, cardiovascular issues such as blood clots and stroke, psychiatric effects including mood changes and aggression, endocrine disruption, reproductive toxicity, and skin sensitization . The misuse of these compounds can lead to dependence . This product is strictly for research and analytical use.

Q6: Why is Methasterone considered a significant substance in anti-doping efforts?

Methasterone and its metabolites are frequently identified in adverse analytical findings (AAFs) by WADA-accredited laboratories, reflecting its persistent abuse in sports . Understanding its metabolic profile is essential for establishing doping violations and extending detection windows for this substance .

Q7: What are the known metabolites of Methasterone?

Research has identified several methasterone metabolites, including MTS-M3 (2α,17α-dimethyl-5ξ-androstane-3α,12ξ,16ξ,17β-tetrol) and M-M4 (18-nor-17β-hydroxymethyl-2α,17α-dimethyl-5α-androst-13-en-3-one) . These metabolites are used as markers for detection in doping control samples .

Q8: What are the predicted toxicological effects of Methasterone?

Computational modeling studies predict that methasterone may have potential for skin sensitisation and can induce reproductive toxicity and endocrine disruption . The potential for hepatotoxicity is considered low, while evidence for carcinogenicity, mutagenicity, and eye irritation is also predicted to be low .

Q9: Is this product approved for human use?

No. This product is a certified reference material for professional use only. It is not approved for human or veterinary therapeutic use. The product is supplied for research, reference standards, and pharmacological research purposes .

Q10: What is the significance of the 17α-alkylation in this compound?

The 17α-methyl group is a common modification for oral anabolic steroids. This alkylation is designed to prevent rapid first-pass metabolism in the liver, thereby increasing oral bioavailability. However, this structural feature also contributes to the compound’s potential for hepatotoxicity .
