Has anyone tried this? Do you recommend stacking it with anything (Nitrojet,e tc.) Can anyone compare it to Swole V2 or V12 Turbo? Also, how many servings do you get from Swole V2 and V12 Turbo? I believe you get 20 servings from BSL Kreataine Ultra for $17.50. What are the numbers for V2 and V12 Turbo? I'm trying to determine the cost/efficacy ratio. Thanks.
