Sorting hype from signal on the newer compounds — 5-Amino-1MQ, SLU-PP-332, SS-31

The newest names always pull the most excitement and the least data. Let's keep a running thread on the emerging compounds — 5-Amino-1MQ, SLU-PP-332, SS-31, and whatever's next. For each: what does the actual literature show (human vs animal vs in vitro), and where does the story get ahead of the evidence? Cite what you bring — 'I heard' doesn't count here.
