Diet diet diet...it's not suppression, it's not because you need an AI. 1/4 andro are non methylated compounds, so they only don't pass through your liver like that. You need to eat a minimum of 4K calories a day of proper foods. If your diet lacks, you'll get negative symptoms. Your body is using its newly converted test to build muscle because you don't have enough nourishment from dieting to allow it to carry to all the good spots. Once you get your diet in check...andro stacks are amazing. Pretty much build hard lean muscle. Seriously up your caloric intake(as clean as you can) and the andro will work better at a lower dose too. Kill it man and stay safe. I just use primeval cycle support and my blood work is fine. Make sure you check your base levels with your doctor before you get started, then compare midway, then after pct. this is a very mild cycle comparable to most, but just like any drug...no calories or proper food=fatigue and zero sex drive. Oh and zero gains.
