Head-to-head comparison of Roxadustat and SLU-PP-332 — mechanism, dosing, side effects, legal status, and pricing.
Roxadustat (Evrenzo) is a small-molecule HIF-prolyl-hydroxylase inhibitor — not a peptide — that raises endogenous erythropoietin. It is an approved prescription drug for anemia of chronic kidney disease in China, Japan, and the EU, but the US FDA rejected it over safety signals. Because it boosts EPO/hemoglobin, it is diverted to the gray market for endurance doping and is WADA-prohibited at all times.
SLU-PP-332 is a small-molecule (non-peptide) pan-agonist of estrogen-related receptors ERRα/β/γ developed at Saint Louis University. Studied preclinically as an exercise mimetic in rodents, it has no human clinical data and is NOT FDA-approved. Sold only as a grey-market research chemical.

Roxadustat is supported by extensive human data as an approved anemia drug (China 2018, Japan 2019–2020, EU 2021 as Evrenzo) with numerous Phase 2/3 CKD trials. The US FDA advisory committee voted against approval in July 2021, citing thrombosis, seizures, infections, and mortality signals. No validated recreational or performance dose exists. Not FDA-approved; not a peptide.
Billon et al. (ACS Chemical Biology, 2023) reported that SLU-PP-332 in sedentary mice increased treadmill endurance, enhanced slow-twitch fiber content, boosted mitochondrial biogenesis, and conferred resistance to high-fat-diet weight gain without exercise training. A follow-up (Billon et al., J Pharmacol Exp Ther, 2024) showed benefits in mouse metabolic-syndrome models. Developed at Saint Louis University (Burris/Walker/Elgendy groups). Rodent/preclinical data ONLY — no human clinical trials have been initiated. Not FDA-approved; not a peptide.
Roxadustat and SLU-PP-332 are both in the Metabolic category and may have overlapping mechanisms. Researchers should review both profiles carefully, understand the mechanisms of action, and monitor the relevant biomarkers when combining compounds in the same class. As always, consult a licensed healthcare provider before making any decisions about combining research compounds.
