Not really, unless you take out the red pill from M-stack and you can mix it, otherwise it’s gone be too much caffeine or energy substances*

I don’t find M Stak to have the same affect as Stak. I’ll go back and use Stak next time*

Such a great product, after a few days once in your system you can really feel the increase of strength, along with its side product of stak taking them for the 3 week’s and alternate them, your strength stays and has no side affects that I’ve noticed, amazing products well worth the money *

It is an excellent product, the bottle lasts 21 days, you rest for 1 week and start again. I go for a week, combine it with creatine, protein, and a high protein, high calorie diet. Bring a capsule with stimulants so it also serves as a preworkout*
