Testosterone derivatives are products containing various forms of androsterone. They are a source of prohormones with high metabolic activity. The strongest androgen naturally occurring in the human body is testosterone. However, numerous studies showed that testosterone derivatives may have a much stronger effect on the development of the musculature while limiting side effects.

In tissues, they are converted into derivatives of the natural androgen, the symbol of masculinity. However, compared to testosterone, they are characterized by the ability to significantly intensify the protein biosynthesis in muscle cells, thus increasing strength and improving post-workout regeneration. They can also be additional support in reducing body fat.

What's more, the body itself regulates the amount of hormone needed to meet metabolic needs. The almost complete absence of side effects such as liver damage, no effect on lipid parameters, or no occurrence of hyperestrogenism, manifested by gynecomastia and decreased libido, definitely supports the consideration of purchasing one of the preparations available in our offer.
