Tribulus Extract 60%

What is the best dosage and time to take this stuff?
And please tell its worthwhile cos I got a kg of this stuff.

Surely you should have researched the product before you go ahead and buy 1kg of it?
Um Muscle Sciences Tribulis 400 Extract caps (standardized for 40 % steroidal saponins) has 400mg packet in each capsule. and they recommend 3 spaced out per day. I use to take 9 per day
How you going to weigh your dosages out?

I have done some research but I get very contradicting information, I thought that the info from the guys that use it would be better.

I haven't been billed for the stuff yet, its about R300 for the 1kg packet about the same for the L-Glutamine.

My folks have a capsule machine so I'll do it at there offices. I will use some use my morning and evening shake, about a teaspoon sounds right.
