As an experiment, today marks the third week I'm taking 400mg tongkat ali (TKA1:200 brand) as well as 2 capsules 500mg horny goat weed 10%, and 1 capsule of 250mg 20% extract.
I'm supplementing this twice a day, first thing in the morning and right before sleep. Both times I'm taking a 200mg Astragin cap with everything to enhance the nutrient absorption. So why the experiment, I've tried these supplements before and never really noticed anything from HGW. Tongkat ali seemed a little overrated to me as well, only noticed a mild energy increase taking Sumatra brand in the past. I wanted to try taking both herbs together in a big dose, plus adding astragin just to top it off.
With this high dose of HGW extract I expected a significant PDE5 inhibition effect, which besides the obvious sexual benefit (viagra is a PDE5 inhibitor), the amount in nitric oxide circulating could also have other effects in the body (as a performance enhancer in sports, perhaps also academic performance boost? ...).
My conclusion. I'm barely capable of functioning 'normally' right now, I have never really felt like I have ADHD/ADD in my life, but chronically taking tongkat and HGW in this fashion I cannot concentrate on anything serious at all. My mind fluctuates in any direction as if I'm a child. Also, libido is really through the roof, as if I'm in my puberty and receiving testosterone treatment all at once. It's simply too much, way too much.
I'm slowly tapering off and will write this off as something I won't be trying again. It's not increasing my quality of life at all!
So well, if anyone wanted to try either of these supplements, you can expect either nothing at all, or annoyingly much of an effect. I have in my attempts not really not noticed much of an in-between.
