I used it for while because of low test blood levels. A single 5mg packet per day isn't going to do much. In fact my serum test levels didn't budge at all after two months on 5mg per day.
When the doc bounced it up to 10mg (2 packets) I could feel a bit of a pump in the gym, but not much. I don't have the link handy, but there is a study comparing 10mg Andro gel\ED to 200mg Test Cyp\per week. In the study the serum test levels were close, but the injected Cyp produced a bit more. If I find it I'll pass it along.
