2 wks in mast only and haven't notice a thing except 4lbs gain. Not any harder or vascular. I am lean already 7% bf. I was running stairs yesterday and had to stop cause my legs felt so tight and pumped, that could also be because taking super pump 250 for preworkout. Nipples actually feel more sensitive not too bad. I though mast u get hard, no water. Just thought I would post on how things are going. 350mg wk.
