Yep, Micro-PA can help. If you’re training for powerlifting but want to put on muscle, make sure you’re doing “bodybuilding-style” accessory work like moderate-to-high reps, an exercise or two per body part, some time under tension stuff. That will help to maximize Micro-PA’s effects.
Also, creatine is basic and very effective for boosting strength and size. It should definitely be a given in a powerlifter’s supp stack.
Yep. Competitors have used it without any problem. You can double-check the specific federation’s banned substance list, but there’s no reason at all why it should be on there.
Yep. That’s the recommended serving size and a fine place to start.
