Hello fellow SABers & myco enthusiasts.
I was wondering, If a mate of mine wanted to start adding Tryptophan to substrates, would a product aimed toward horses be no worse than a product aimed toward humans?
Here is the equine product: http://www.ebay.com.au/itm/Tryptophan-Powder-for-Horses-1KG-/301917770249?epid=714386116&hash=item464bb39209:g:BHIAAOSwZ8ZXANRt
Here is the human product: http://www.ebay.com.au/itm/L-Tryptophan-Powder-908g-sleep-aid-weight-loss-FREE-WORLD-SHIPPING/152447930547?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
I've read that L-Tryptophan is the stuff that is needed, and that maybe it comes in two isomers (L & D).
I'm wondering if that horse Tryptophan (even though it doesn't have L- in front of it) is it the same, or just as effective as the L-tryptophan from the other link? Dosage seems to be in similar range for horses as humans.
Also while I'm on the topic, does anyone know of any good places they recommend for pharmaceutical grade L-Tryptophan? $80ish a kg seems to be around the best we've seen.
