I was a responder. Responder being a vague word in itself, as is many. How well someone responded seems more of what i mean. I responded well early on while taking it. muscles harder and fuller the first 2 weeks. after that I stayed with the dosage and then the feelings and gains seized. but never had any strength gains, which was odd. I should have upped the dose and i could have been a better run.
My curiosity is i wonder those that are nonresponders to prime, i wonder what else they don't respond well to. Possibly other test boosters or herbal testboosters along the lines of tribulus and etc...Might be a good thing for us to log sometime or research @ least.
