I wanted to do this comparison because Tesamorelin and MK677 both increase growth hormone, but they are very different once you start looking at the details. Tesamorelin has some really solid human data for visceral fat and seems cleaner when it comes to glucose control, while MK677 is much more convenient and has its own advantages for appetite, growth hormone, and body composition, but it can also come with more issues around insulin sensitivity and water retention. The biggest problem is that we still do not have the exact head to head studies I would want to see, so a lot of this comes down to combining the research with real world experience. What would matter more to you when choosing between them: muscle, visceral fat, glucose control, or convenience? https://youtu.be/jVVymI2sMpU?si=lr-9cUkZQ7psdWMi
