Citrulline as a supplement

Anybody try this?
It's not particularly expensive. Very tart taste, which I like.
I've tried a 3 gm dose prior to training, haven't really noticed much for good or ill.
Will increase towards the 8 gm recommended in this article
climbingnutrition.com/suppl…
and report back.

I take 1/2 tsp of Beta A and 1/2 tsp of Cit M exactly 1 hour before starting climbing. I've noticed a big difference in power endurance. No noticeable effect when bouldering, unless its a longer problem

The taste of the 2 mixed together in water is something akin to battery acid, but after a while it really isn't all that hard.
