Oral steroids are a type of performance-enhancing drug that can be taken by athletes and bodybuilders to increase muscle mass and strength. One of the most popular oral steroids for muscle mass is methandienone, also known as Dianabol. This steroid is known to increase protein synthesis and nitrogen retention in the muscles, leading to significant gains in muscle mass and strength.
Enclomiphene citrate is another oral steroid that is sometimes used to increase muscle mass. This drug is actually a selective estrogen receptor modulator (SERM) that is typically used to treat infertility in women. However, some athletes and bodybuilders have used it off-label to increase testosterone levels and improve muscle growth.
