It does sound crazy, but I tried it. I dropped from 280-238, and my bodyfat dropped over 10%. I only lost around 3-4lbs of lean mass in the process, verified by body scans. Also I am now 3 months + out of my cycle and I am 236lbs right now. Furthermore I have dropped an additional 3% bodyfat since ending HCG. I will say that my success has a lot to do with following a slow reintroduction to foods and monitoring my calories for 5 weeks after my last shot. I maintained for that period, then switched to a keto style diet. I think that you will definitely rebound if you do not maintain your new weight immediately following your completion of an hcg cycle. I will respectfully disagree with the assurtion that HCG is in effective, I have my personal experience as well as 4 family members who had results similar to mine. I think all the bad rap about hcg has to do with fake hcg or the drops. I did injections every day and it worked.
