Well Anabolic Pump and X factor are different supps altogether. ive tried both and AP for me was outstanding for hte first few weeks. one of the best things was a rapid hunger increase. i could polish down a huge meal of chicken and rice and 20 mins later easily down another meal the same size. it lasted for a week or two then died down a bit. the pumps lasted well into the next day. eg i train arms on a monday, i wake up and they're a bit sore, pop an AP followed by a big carb meal and they start to feel pumped again, do it again at lunch time and by tuesday afternoon i feel like ive just trained bi's again. sweet feeling if u ask me.
X factor i didnt think worked that great for me until hte end of the 50 days when i started hitting some nice pr's on bench and shoulder press while consuming fewer calories and increasing cardio from nothing to 45 mins 5 times per week. was not expecting to increase strength during a cut but i did and i have to thank XF for that.
