I started taking 300 mg of test split into 3 injections(Monday, Thursday, Saturday.) from a new source. I started this exactly on march 28th and I went through a whole vial of 250/ml test cyp. I have been drawing exactly 0.4 ml everytime(100 mg). So either this vial is 5 ml or I have been somehow been doing double which wouldn’t make sense. Any advice?

Also note** I forgot to mention the vial is the same size as the other brand that is 10 ml, which makes it even weirder

Another note*** I’m on my second vial btw the first that was supposedly 10 ml lasted 1 monthish
