I put dog on the Cardarine and RAD 140 stack tabs from PureRawz 3 days ago. He said that he doesn't feel any benefits yet. He has noticed that his ears ring a bit. Also I noticed that the two pills are identical in size, shape, color and texture and even the logo on them is the same. I have worked in the pharmaceutical industry on the manufacturing side and they always make the pills different incase the user mixes them up they can figure out which is which. I will keep you posted.
