SLU-PP-332 against Cardarine
The newest exercise mimetic and the one that has been sold the longest. SLU-PP-332 has no human data of any kind; Cardarine has a rodent carcinogenicity report and a WADA ban, which is more information, just not the reassuring kind.
Column A
SLU-PP-332SLU-PP-332 (ERR agonist exercise mimetic)
An experimental 'exercise mimetic' that activates energy-metabolism pathways in animals, with no human data yet.
Column B
CardarineGW501516 (cardarine)
A PPAR-delta agonist GSK stopped developing, reportedly after long-term rodent studies produced cancers in multiple organs; still sold widely for endurance and fat loss despite that report and a WADA ban.
