SLU-PP-332

What is SLU-PP-332?

SLU-PP-332 is a synthetic exercise-mimetic research compound designed to activate the estrogen-related receptor family: ERR alpha, ERR beta, and ERR gamma. ERRs are orphan nuclear receptors that work with PGC-1 alpha to regulate mitochondrial biogenesis, fatty acid oxidation, oxidative muscle-fiber programs, and energy metabolism. In plain English, SLU-PP-332 tries to flip part of the same transcriptional switch endurance training flips.

How it is thought to work

Activates estrogen-related receptor alpha, beta, and gamma, which partner with PGC-1 alpha to regulate mitochondrial biogenesis, fatty acid oxidation, oxidative muscle-fiber programs, and hepatic lipid handling.

Safety watch-outs

• Severe agitation or insomnia
• New muscle pain or weakness
