Be careful to make sure all your compound is in the bottom of the ampel. Last night I popped a bottle drew it up and I'm like wtf. They shorted me ,I only got a 1/2 ml. I was smoking pissed ,I went to pop another ampel and realized. Half of my sustan was in the top half of ampel. So when I grabbed the ampel and didn't look I just snapped the top off well I guess a snapped off a 1/2 ml of gear also ..what a waste. Smh. I was ready to contact source like hey what kind of game you running .. I would have looked pretty stupid considering it pharma also. .. But be cautious
