Re: HCG sides?
As said if you want to lose weigh, there are far more affective things. I'd start with a reasonable calorific deficit. If you want some help then there is: Clen, ECA and (DNP). I'm putting the DNP in brackets because I wouldn't recommend it unless you know exactly what you are doing and can handle it. It's the only compound I've ever taken which I wasn't able to cope with.
Fortunately losing fat is very easy. But there has been a whole industry built up trying to convince you otherwise. Just eat a bit less. Track your calories. Possibly look into a keto diet. Throw in some cardio, if you are unfit this can be as simple as walking. If you are fitter then HIIT is great. Then weigh yourself (and take photos) if you havn't lost weight for a week or two lower the cals or up the training. It's that simple.
