Growth Factor XT is the best sleep aid Ive ever taken but I get estrogen sides from the Chlorophytum believe or not. So Ive sourced Pharma Gaba which is an ingredient in it and stack it with Valerian along with Pregnenolone (5-10mg) and ZM8 (Mutant brand). Thats the combo that works for me. I do cycle it though maybe a few days on and one or two off. Outside of this CBD oil works on days when my sore back flares up.
