I’ve used several Hgh sources over the years. I think this will be my new source . When you weigh out everything... They’re domestic, very reasonably priced, and most importantly a great product. Check out my lab test. So I hadn’t take any Hgh for about 6 weeks. My baseline igf1 was at 66. I have these labs posted on here also. I took 5ius split am and pm, 5 on and 2 off. Felt all the sides and improvement in sleep and skin. Energy increase as well. Igf1 is now 321 almost 5 times my baseline.
