This isn't my first rodeo. Yes I am running test and other compounds. Tren hex is similar to parabolan of the old. 100mg/ml is not a low dose. It was originally dosed at 75mg/ml before they pulled it off of the market. Looking for dosages per week. I will start at 200mg, but will bump up if I can handle the effects of the longer ester. 400mg per week going once.....................
