Ok so first dose was pretty good on taste , a bit chalky with 16 0z of water but not overwhelmingly orangey. I liked it for lack of chemical taste , but the pump effects and fullness i soon felt twenty mins after finishing my drink and i took a caffeine tab and started chest routine , with 10 ,8,6,4,2 as my rep scheme and after first two sets i noticed a great pump , not phenomenal or unbelieveable like other pres ive tried but u can always add nitrates or other ingredients yourself so thats a plus with this product , i definitely noticed strength increase as i got down to my nitty gritty part the last couple sets of heavy , and i have to say im impressed so far .
