Any links for supplement dosages... (not AAS)

[shawnkarbabacz]

Can anyone shoot me a link for a reputable site for supp dosage. For example, im about 215 and am wondering how much grapefruit extract (in addition to a few other things) i should take in, as ive been reading up on it and am gonna give it a try, especially since its so cheap.

I dont wanna waste anybodys time on constantly asking specific questions about dosage, but i also cant find a GOOD site to look it up myself.

Help?
