all oppinion, all mine have been filled correctly, and I havent noticed any differnce in strength compared to regular sust redi jects that run 15 bucks a pop...

no matter where you buy your sust, its gonna be about 6 bucks per amp... but a 10cc vial of supertest is 30-35 bucks... comes out to 3.50 per cc... even if it was a tad underdosed, it still is a good deal and I have never had any complaints with it since 1998.

but, then again I can practicly walk across the street to get it... other folks have to get whats availiable to them and ST250 may not be on the top of thier list...
