It can be around a 10th of an ml per injection in terms of waste. That's 0.20ml per week if you're injecting 2x/wk. If you're injecting a total of 100mg/wk or 50mg/2x/wk, that turns into a massive amount of waste. Should you be losing that much? No, only if you're being careless and not paying attention to what you're doing. And here's another little bit of info, Empower fills each 10ml bottle with 11.5ml to account for waste. Started doing so several months ago and still people ran out early. So what's the moral of the story? Most are lying and taking more than they're supposed to
BTW, the videos have been redone. Were redone awhile ago.
