Plazma - I honestly don’t even remember what DOMS feels like and I’m approaching 40 in a few months. Gym sessions used to leave me tanked after about an hour. Now, I can honestly go for two hours and leave only because of the time on the clock. I run circles around people half my age and the only rest periods I take are to to add weight or take it off the bar. There isn’t any supplement, ever, that even comes close to this one.
MAG10 - For much the same reasons as Plazma, I’ve used both. MAG10, I’ve used pre, during, post workout. Also for pulsing and meal replacements, mostly snacks. Definitely the most versatile product.
Indigo - Carbs, need I say more? They were never an issue for me until my mid 30’s and it allowed me to actually eat carbs, lots of carbs, without fear and my body composition actually changed for the better, as did my mood and energy levels.
Brain Candy - I’ll have to steal PB Andy’s response here. It’s awesome stuff.
ZMA - I have a fairly physical job in a warehouse, a house to keep and a baby at home (that still doesn’t sleep through the night). This allows me to actually feel like I’ve slept and without all of the calf and foot cramps. Without it, doesn’t matter how long I’ve slept, I wake up feeling like I was hit by a train. This one’s a staple.
It’s really hard to narrow it down to five!
