Ok did a bottle, 180 caps of these. I had never done any gh enhancer previously, so i did not know what to expect... Honestly i do not think they were a factor at all if any. I believe the company used the letters gh or growth hormone to get customers to buy their product. if it does release any gh, its a tiny amount and is not enough to make a gain/difference.You should save your time and your money and not bother with this product.
