So, I already posted this in the supp section and was directed here. But I started takkng hemavol all 10 pre workout and i took them with water, and I went to take a **** and about half and hour after I took them I start getting full of blood and hot and really pumped up, I was like wow this is awesome, great! Took some jack3d and then hit the gym, had the best workout I've had in months...! I was so happy. Two days later took them for my next workout, I always go on near empty stomach, and I took the hemavol... And nothing. No pump no bigger arms even less veins... What's going on. I had great results one day and nothing the next, and this repeated again next workout... I don't get it. I'm tons go take them and workout today, ill let you know how it goes. I'm trying to vary the amount t of water I drink. In gona bump it up today. Anyone have any ideas what's going on ?
