I absolutely love this product. Sleep is one of the most underrated pieces of the growth puzzle. You will not recover from your hard work without it. AI Sports has you covered here. You get the best of both worlds with a combo of the zinc/magnesium necessary but also some great relaxation and GH releasing ingredients. This will not knock you out. What it will do is relax you and then once asleep you will enjoy a very solid/restful night's sleep. I also like that it does not have melatonin in it to screw with your natural production of that. For $20 I can't see how you could go wrong. Make sure you don't eat anything with calcium before dosing as this will hinder the absorbtion of the zinc/magnesium.
