Methyltestosterone is simply testosterone with an added methyl group at c-17, which slows its liver breakdown. This testosterone variant did seem to work as an oral androgen supplement during the early years of medical use. One of the main issues is that it tends to be highly estrogenic. It turns out that this is because methyltestosterone readily converts to a very potent.
Methyl test is highly recommended as the base of both mass building and cutting cycles. Testosterone is responsible for promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining lean muscle mass, preventing osteoporosis.
