does anybody know how to start your own supplement line and where to go/call or look to get started?
How about approaching any of the myriad company owners on the board and asking them - since there's no one who's going to know better than they.
For example (this is by no means a complete list):
Don Orrell aka don orrell of Applied Nutriceuticals
Josh Poole aka nattydisaster of PES
Armando Lopez aka GENOMYX from Genomyx
Matt Pearson aka dsade formerly of RPN
Eric Potratz aka Primordial Perf from Primordial Performance
Eric Marchewitz aka LG Sciences from LG Sciences
