I bought some supplements, that I originally planned to use. BSN Cell Mass BSN True Mass 100% Whey BSN Nitrix BSN No-Xplode Muscle Tech Anator P70 Muscle Tech Leukic I haven't used any of them yet, and I'll explain why. I was at Wal-Mart today, looking to buy some ammo, and I cruised through various isles, until I seen some supplements, and pills. Assuming that it's Wal-Mart, I passed on the supplements, but seen some pills that caught my intrest. Oxylene Akg They were marked down to $4.50 a bottle, so I copped one. It says that it improves oxygen delivery to cells, promote maximum circulation and vascular bloodflow, increase stamina, endurance, and stimulates lean muscle mass production, oxidized fat burning, to improve overall physique. So I started taking it. The results were, I felt NO fatigue when working out, I was EXTREMELY clear headed, and focused. These pills are def worth the price. I found them here, http://www.fitnessmountain.com/index.asp?PageAction=VIEWPROD&ProdID=1604 These are the cheapest I've found them online, you may be able to find them cheaper offline. DEF worth a try.
