17 Hydroxy-MESTERONE is a raw material hydrolyzed from the "genus" smilax, which you may be familiar with because it's been marketed in the United States as a natural anabolic for over 20 years! Anabolic components of the smilax plant called Dioscins are hydrolyzed (Hydrolyzation is the rearranging of carbon and oxygen molecules in the compound structure) to produce diosgenins. Diosgenins are the actual steroid like components of smilax that have been used for years as a raw material "starting point" for pharmaceutical companies making anabolic steroids. Historically synthetic testosterone was created from the yam plant after discovering the hormonal structure of the yam plant was virtually identical to human testosterone. However, conclusive scientific data shows that the natural steroid Diosgenins of smilax attach to androgen receptors over 300% more efficiently than the yam . . meaning more androgen receptors are occupied . . . thus allowing for much faster protein turnover.

In addition to Hydroxylation, 17 Hydroxy-MESTERONE has had two sugar molecules cleaved off to greatly reduce the production of Aromatase, which is the enzyme that converts testosterone into estrogen. If estrogen levels increase, hard lines disappear leaving a swollen bloated physique.
