Always warm up too.
Yes.
This is hugely imprtant. Heat will draw blood to the area, and make the tissue more pliable. The warm-up recommended in the newbie routine should be considered a minimum.
Personally I recommend a 15-20 minute warm-up, in keeping with the physical therapy ideal, and then sustained heat throughout the routine.
Any of the penis supplements that are specifically marketed as such are WAY overpriced and make promises that can’t be true.
Those supplements do promote blood flow and vasodilation, but for their price..?
The labels reveal the usual suspects of herbal ingredients. If you research you can buy these much cheaper and increase effectiveness to boot.
None of them will grow your dick, but a few might improve erection quality.
L-Arginine is an amino acid and vasodilator. You can buy NoX-2 and get far superior ‘penis’ results with this alone.
Yohimbe will also promote blood flow as well as being a natural energy boost. (FYI: too much of this can cause hallucinations and can be fatal - don’t worry the recommended doses found in most yohimbe supplements are far from either of these side effects, but it’s good to know - more is not better).
Ginseng. Good quality ginseng will help your aerobic function and should also be noticeable in terms of your erection. Organic Panax Ginseng is very good. You can get it in pills or a liquid. The stuff will boost energy and increase blood flow to some degree.
Maca Root seems to increase my semen load (as does Arginine - provided I drink a lot of water as well).
As far as tongkat ali, avena sativa, and others, I am unclear as to their efficacy.
One last thing. Vig-Rx and Magna-Rx and these other penis pills, while listing their ingredients, often say “A proprietary blend” which means you don’t know how much of which ingredients you are getting. Further, you have no idea of the quality of these ingredients.
If you want to look into supplements do extensive reading.
Also, if you are in your 20’s … do you need this stuff? Probably not.
