Tweetok .. dude at my job did this ,and it worked great however the calorie restricted diet alone that goes with the HCG shot will get you to drop mad weight. it was like 5 to 800 cals a day . it was like all he ate was rabbit food and water so sure it will work so for me I don't know what pivotal role the HGC played in his weight lose..
he has also kept the weight off for over a year but that's only due to a change in diet..
