SO youre basing things off a 22 year old study...in rat boners?
Ha yeah but that's just for one, and it being 22 years does not make it any less significant, there are plenty of studies showing this ... and plenty of anecdotal evidence. Testosterone will have positive impact on NO and pumps, for sure. Boners is more hit and miss.
Nitric oxide increases your pump in the muscle but also the erection of your penis. So I would think both go hand in hand.
Vince, there are similarities but I would not say they go hand in hand. There is a stronger influence of blood flow and NO with your penis. The penis is more purely a cardiovascular indicator. In the muscles this is also important, but there is also the role of glycogen loading, which unfortunately declines with age, but is restored to a degree with TRT. When the muscles load and utilize glycogen for short-term energy, this contributes greatly to the localized pump sensation.
I've been on thyroid meds for a long time, too long to notice a difference.Vince if i remember correctly you take thyroid medication along with trt. Have you noticed a difference in muscle pump while taking thyroid medication?
A lot of young man make good levels of nitric oxide, what I was young I was one of them. Very easy for me to get a pump in the gym. Now that my body doesn't make as much nitric oxide, I need a good nitric oxide stack.
Appreciated your post on nitric oxide stack, I followed it and at the age of 53, the pumps I am getting at gym are first class
I never thought I could gain muscle the way I am at this age
