Ive used QV, TToykko, and supra but my favorite is a 100cc Bottle of Columbian Ganabol, just picked up 3 of em. Only 50mg per ml, but at 1,000mg per week, it is unreal.
Its 20cc 's I know but using it for site injecting really expands the tissue well before lifting. I seem to get a better dispersion if I shoot the site I am going to work for the day.
