L-tryptophane ?

["Drin Becker" <rainbow@montana.com>]

Hi Guys ,
Has anyone out there used L-tryptophane on a gelding ? This guy the vet said
is still producing testosterone even after being gelded at a very young
ge( 3 months) but the drawback is the more L-tryptophane you use the more
you need if using it on a regular basis ....is this a problem for an
endurance horse ? The gelding is now a 7 year old and very very stud like
behavior . Thanks  guys
