I am trying to find out what I can about these. Old post, but figured I'd give it a shot. Currently using the blue tops with the gold diamond logo. Haven't really felt the sides too much. I tried increasing the dosage for a day or two but not much difference. Sometimes I get a headache after pinning and occasionally get joint pains. I'm guessing these are just really under dosed, but not sure because I am new to GH. Any help is appreciated.
