Promagnon 25 is a highly effective lean muscle mass and strength enhancing catalyst, scientifically engineered to support rapid gains in muscle strength, size and power. Because ProMagnon-25 cannot aromatize to estrogen, water retention (and the soft puffy, bloated look that goes with it) is minimized. In addition to exceptional massand strength gains, users may also nitice marked increases in energy levels, endurance, libido and lipolysis (fat loss). As with most dietary supplements, ProMagnon-25 is intended to compliment a proper diet and training program.


As a muscle builder, Promagnon 25 is a very mild steroid. Even though it has a 17aMethyl delivery system it’s not as harsh as the other prosteroids like Superdrol. This is likely due to the 4-Chloro group reducing many of the metabolites and the diol structure. Cycles are usually between 25 and 50mg per day orally with very few side effects.
