i am refering to aromatization of test through the 5-alpha reductase enzyme to dht some studies have shown that gamma linolenic,zinc and Alzeic Acid can reduce the 5-alpha reductase by upto 90%.at the moment i take evening primrose,vitamin b6 and zinc,i cant say 100% that they work but im having no probs,these chemicals can be found in remedies such as rivivogen etc,i also use nizarol shampoo just incase.for other substances like tren these would not work another approuch maybe necessary.
