There is no greater muscle building nutrient than regular old food (good, healthy food of course, lean proteins and complex carbs like veggies and oats).

But eating food (or even taking supplements) won’t work if you don’t then stimulate the muscle to grow. That means lifting heavy weights.

Use supplements only as a last stage, not a first stage. This applies no matter what your blood pressure. (And yes, you can lift heavy weights with high blood pressure but you have to watch your breathing – don’t hold your breath during the lift. See a doctor first.)
