The best prohormone available is 1-Andro, according to MindandMuscle.com. It is a legal prohormone that converts to 1-testosterone. One of the benefits of 1-Andro is that it does not convert to estrogen or DHT, which can result in hair loss and enlarged breasts in men.
Another benefit is that when used in conjunction with proper diet and exercise, 1-Andro can help a person build up to 12lbs of muscle and lose about 6lbs of fat within a month, according to Leanbulk.com. However, the legality of 1-Andro does not mean it is safe to use. The 1-Andro prohormone can have a detrimental effect on a person’s liver and kidneys, claims Suppversity.com.
