Satyricon331 saidOver the past number of months, my arms (and much to my horror, my legs have lately joined in) have exhibited much too much vasculature. I don’t want them super-veiny but I’d like to continue to progress on my muscle development. Is there a way to suppress vein growth without stopping my exercising?
I can’t believe there are guys who blow money on NO boosters just to make their veins more visible
Vascularization / capillarization is a normal part of your body's adaption to exercise and improving your blood flow. I.e., your plumbing improves to enhance the performance of the human machine. Some of the side effects are improved circulation, better recovery, better performance, and lower blood pressure. It's a very GOOD thing.
At very low fat percentages, and being "dry", vascularity is very visible in highly conditioned individuals.
You can't have good vascularization without being in excellent condition. It's a sign that your body is adapting in a good way by improving your cardiovascular system under load.
With someone underweight such as yourself, as your cardiac tone improves, you'll be able to easily see the results. It's good for you. If you don't like it, you should EAT, and take on a fuller appearance.
When you can see veins everywhere, you are, without doubt, lean and fit.
Incidentally, the more you exercise, the better your blood supply will become. It's how the human machine works. Don't fight it.
