Many supplements include both Maca and HGW (pre-mixed), because in fact they do work well together. However, Maca and HGW are derived from 2 different plants, and neither contains any percentage of the other. Personally, I think the combination will put Tribulus to shame

My only suggestions would be:

1. Move 1gr Tryptophan from Bedtime to Lunch.
--- Reason: You need this to be activated and converted into 5 HTP & Serotonin while you're awake.

2. Arginine dose is super entry level. Consider at least doubling.
--- Reason: 500mg is not enough to increase vessel circumference, the main reason we need Arginine.

3. Get Maca and try it without Tribulus, if all goes well, drop Tribulus.
--- Reason: The combinations list of benefits includes everything Tribulus does and much much more.

4. Get Vitamin E and start taking it at the same time you take Cod Liver Oil.
--- Reason: Vitamin E will protect the essential fatty acids so that they don't mostly go to waste.

Hooray, supplements!
