You don't have to find a vein right? What about how deep you have to go like can you just go SubQ deep with an insulin needle? I don't think i'm willing to use a 1" for this purpose but if i could get away with a small one I'd probably do them.
Will it have a noticeable effect on mood and energy? My gym sessions are really lagging lately. I made it through dead lifts today and wanted to do some barbell / dumbbell rows and just felt dead. Ended up doing some biceps and calling it a day.
