If you are uncertain of your source, you could look into nutrobal as an alternative to HGH. Nutrobal is an HGH analogue. It signals the pituitary gland to increase HGH output. I would say it's equivalent to about 3-4IU of pharmacy grade HGH per day. 25mg/day is a good dosage. You can read up more on it here:
