Comparing HGH peptides and incretin mimetics benefits

In my area, there has been a lot of buzz lately about HGH peptides and incretin mimetics, and I’m wondering how their benefits really compare. I’ve read that both have potential for fat loss and metabolism improvement, but they seem to work differently. I’m particularly interested in understanding which one might offer better support for muscle repair and fat mobilization over time. Has anyone here tried either or both and noticed a clear difference in benefits? Also, does the speed at which these compounds work affect their usefulness for different goals? I’d appreciate real-world insights or any advice on how to decide between them.
