just a few ive tried over the yrs that dont measure up, not trying to knock these products but when push comes to shove they dont cut it.

hgh pro
hgh up
IGF2
powerfull
humano grow
All of the NOW GH products
any Velvet HGH Spray
lg sciences ghenerate
LG IGF1

to be honest NOW L-dopa is the next best thing IMHO. I got as good of results from that as i did from all the others.
