This is a side-by-side of what is documented, not a ranking. Different compounds are studied for different things, in different people, at different amounts. A row that looks stronger for one compound does not make it the better choice for anyone.

| What is not known | Long-term safety over years of continuous use, including cardiovascular, cancer-risk, and pregnancy data, has not been established at this stage of development. Whether the strong phase 1b/2a and phase 2 results will hold up in larger, longer phase 3 trials, and when or whether the... | Whether survodutide raises energy expenditure in a human being. That is the central mechanistic claim made for the compound, it rests on rodent indirect calorimetry that reached significance at one dose on two days with no change in core temperature or activity, and it has... |
