I used Blue Growth mainly as a sleep aid. I use sleep aides for 2 reason, to help fall asleep and wake up more refreshed. Well, Blue Growth does help sleep deeper and wake more refreshed, however it does not help me fall asleep. I understand it's not completely a sleep aide, but that is one of the big points of natural GH products. It does have some ingredients to also optimize test levels. I like the addition of LCLT and Alpha-GPC. Frankly, It's an expensive product, but it uses expensive ingredients! I would like to see Melatonin or GABA added to help with falling asleep, but Melatonin is inexpensive to add. Some ZMA would be a nice addition too, hit it from all angles, but more ingredients would add to the price. Overall, this is a solid product.
