Is this pro-horomone (17a-methyl-17beta-hydroxyestra-4,9(10)dien-3-one) a better alternative to say something like methyl 1t. I am interested in pro-horomones but whating till I am 21, and gains slow down. Would this be a product to load up on, and save for the future, before its gone for ever. I also have a bottle of MHP T- bomb, and and Twin Labs Andro Fuel, are this products similar as far as positves, and negatives. I am just wondering is this less harmful, and less negative side effects. thanks alot. mark
