I love this product. this is 100% real authentic and reliable. I have used other hgh in past but after using this one i am pretty sure whenever i can afford i will go for pharma grade authentic hgh. almost 2 months into this hgh and i am seeing my body fat dropping faster and getting leaner with no change in diet. One of the most important thing to have noticed is the amazing sleep and fast recovery. For quite sometime i switched to one muscle group per day training but with hgh i can train two muscle groups a day and more frequently a week. The resting time between sets have also decreased. My stamina has improved big time. I can go to gym job play sports and also do daily life activities without any problem. Not feeling tired, lazy or off mood anymore. For dosing sometimes i do all 4 ius at once whereas sometimes split in two doses pre workout and before bed.
