In my view, when you compare them with real gh, gh secretagogues simply aren't worth the time or the money. The real thing is what you should inject; it's fairly harmless, and side effects are minimal or absent for most users. My own routine is 4-5 iu daily, and every so often I feel tingles; I mostly improvise according to how the sides hit me, and the results have been excellent.
Fat loss aimed at particular spots isn't truly achievable. I get that certain GLPs and gh secretagogues such as tesa will target visceral fat, yet broadly speaking, the body strips fat away in the opposite sequence from how it was laid down.
As for chubby legs, my top suggestion is heavy squats, so at minimum they end up with better shape. Beyond that, stronger legs are able to burn additional calories.
