I am curious about this list. You are planning on raising testosterone with it? Or do you have another goal?

I have some quick observations:
1) Try and keep your B6 at a 50mg a day dose. Anything over that risks side effects.

2) 200mcg of selenium is quite a bit. New guidelines point to 100mcg daily.

3) It is best to have a zinc/copper ratio done before starting supplements of either.

4) It is also best to get your D3 evaluated so you can choose an appropriate dose.

5) have you had your B12 measured? Don't assume your combination B products will properly ensure any tiny amount of B12 in them will be absorbed.

6) What form of magnesium are you using? Is it Oxide? That form is not absorbed and stays in the bowel to be eliminated.

7) if you had chickenpox in the past, using high dose arginine for long periods may trigger shingles. Arginine is used by dormant Herpes zoster virus to replicate/activate.

Males looking to increase testosterone, typically need some hormone testing including DHEA levels. If DHEA is low, then the doctor may suggest you supplement with it and what dose to use. If you have low testosterone, and have testing to reveal that, then looking at your medications(opiates for example) as a cause or a genetic cause of DNA errors like Klinefelter's syndrome should be done as well. If a DNA error is revealed then those patients typically are given testosterone replacement treatments.
