hCG never worked for fat loss, beyond the effect it had in raising gonadotropins and therefore natural testosterone levels, which were the real cause of the mild body recomposition effects it had. Testosterone is way better at reducing fat mass and increasing lean mass, over time at least.
hCG can be used for preventing testicular atrophy on TRT doses of testosterone and possibly/probably also fertility although it does not (contrary to popular belief) work in everyone, especially those who have been on exogenous testosterone for many years before starting hCG.
