11oxo, also known as 11-Ketotestosterone or Adrenosterone, is a prohormone that is derived from testosterone. Prohormones are substances that can be converted into active hormones in the body, such as testosterone or estrogen. 11oxo is specifically known for its potential effects on increasing lean muscle mass, promoting fat loss, and enhancing athletic performance.


As a prohormone, 11oxo works by converting into 11-ketotestosterone in the body, which has similar effects to testosterone. It may help support protein synthesis, which is crucial for muscle building, and promote a positive nitrogen balance for enhanced recovery and muscle growth. Additionally, it may have a mild anti-estrogenic effect, potentially reducing water retention and supporting a leaner physique.



Trenavol is the prohormone derived from Trenbolone (nandrolone), which is a hormone found naturally in the body. It was originally developed for veterinary use to promote muscle growth in livestock.


Trenavol is highly regarded for its potent anabolic properties, making it popular among bodybuilders and athletes seeking to enhance their physical performance and muscle development. It is known for its ability to increase nitrogen retention, which is essential for protein synthesis and muscle growth. Trenavol is also believed to have a strong binding affinity to the androgen receptor, which contributes to its anabolic effects.



Decalone is the prohormone to Deca-Durabolin, this is a brand name for the anabolic steroid called nandrolone decanoate. Decalone is a synthetic derivative of testosterone, a hormone naturally produced in the body. Decalone is primarily used in the medical field to treat conditions such as anemia, osteoporosis, and certain types of muscle wasting diseases.


As a prohormone, Decalone is known for its ability to promote muscle growth and enhance athletic performance. It works by increasing nitrogen retention, which is vital for protein synthesis and muscle development. Decalone also has a reputation for providing joint pain relief and improving collagen synthesis, potentially benefiting athletes engaged in intense training and heavy weightlifting.



M1,4ADD, also known as Methyl-1,4-androstenediol, is a prohormone or designer steroid that was once available in the supplement market. It is a derivative of the hormone testosterone and is designed to be converted into an active hormone in the body.


M1,4ADD is known for its potential to enhance muscle growth, strength, and performance. It is believed to increase protein synthesis, which can lead to greater muscle mass gains. Additionally, it may improve nitrogen retention and promote a positive anabolic environment in the body.
