300MGX1 a week@10 weeks=10ML right?

300MG of deca a week for 10 weeks = 10ML right?

:scratch:

I've seen deca in various concentrations. 200mg/ml 250mg/ml 300mg/ml etc.

yea , depends on what mg/ml your deca is

We have to know what the concentration is of the deca like eGGz said. It should say on your bottle how many mg/ml.
