Don't use scienceBio! I was in middle of a cycle of Rad140 that I had purchased from sarms4sale at the time I only purchased 2 bottles. I was running low so went to purchase another and it must have been between productions because I couldn't get it. I foolishly bought a bottle from Sciencebio and a week later knew something wasn't right. I stopped taking it and went to get some labs done. They were without a doubt oral steroids. Do yourself a favor and buy everything you need to complete the cycle upfront from sarms4sale.
