A good agmatine sulfate is NOT cheap by any means.. how much did you pay for 150g? on bb.com agmatine from primaforce is 16.99 and thats only 30g, to me thats stupid expensive for a pump product.. For the sake of getting a pump its not worth the money.
Citrulline malate is much better, even though i dont get any pumps, no matter what i do or take.. When i was fat i was getting ridiculous pumps to the point that my bicep would hurt, now that im lean i dont get them, not sure why.
