assault= king in my book I love this back in the day they had suma root that shi@#@# was real!!!!! but the new batch is vey good too...
Jack=Stim big deal I have never tried 1MR.. but if you looking for a stim pre drink then Assault wil not give you what jack has ( super stim ).. But if you alooking for a true pre workout that will give the power pumps endurance and gives you this
Creapure (Creatine Monohydrate), CON-CRET® Creatine HCL (100% Concentrated Creatine), L-Glutamine Then buy it!!!!! Jack is BS to me I used it I have even loged it Secound class product...
