"in the PDR, they state use for weight loss as a contraindication", Yes, I know. That's why I'm gob-smacked at this post. I'm also shocked for the same reasons Temple mentioned.
One of the best controlled double-blind placebo controlled trials I know of (using IM rather than SubQ) found "Subjects receiving HCG injections showed no advantages over those on placebo in respect of any of the variables recorded. Furthermore, weight loss on our diet was similar to that on severely restricted intake. We conclude that there is no rationale for the use of HCG injections in the treatment of obesity."....which is why I mentioned to delinquent that the 800 cal diet ALONE would have those dramatic weight loss effects, and that I seriously suggest he convince his girlfriend's sister to stop this nonsense.
