Product Description
17-Methyltestosterone Powder is a modified testosterone compound featuring a methyl group attached to the 17-alpha position of the steroid structure. This structural modification creates a distinct compound compared with natural testosterone and esterified testosterone derivatives such as Testosterone Propionate, Testosterone Enanthate, and Testosterone Cypionate.
The compound is known for its well-defined chemical structure, stable crystalline form, and consistent purity profile. High-quality 17-Methyltestosterone Powder is produced through controlled manufacturing processes and undergoes analytical testing to verify identity, composition, and overall quality.
Due to its specific molecular characteristics, 17-Methyltestosterone is an important reference compound within pharmaceutical and biochemical fields. Its unique chemical structure makes it valuable for scientific research, analytical applications, and studies requiring accurately defined steroid-based materials.
The powder should be stored under suitable environmental conditions to maintain its stability and physical properties. Protection from moisture, excessive heat, and direct light helps preserve the material’s integrity throughout its storage period.
