The first thing I'd ask is your age. Next would be to lay out your diet...as there's a couple things I'd cut out right off the bat if your diet isnt in check. Also I personally prefer usplabs modern bcaas or the 4:1:1 BCAA powder from trueprotein over the purple wraath.
Last things...i find that im usually better off becoming tired naturally and sleeping a full 7-9 hours rather than taking melatonin. How much fish oil and cla are you taking, too?
