ACE-031 (ramatercept) is a soluble fusion protein of the activin receptor IIB (ActRIIB) extracellular domain and human IgG1 Fc, developed by Acceleron Pharma as a myostatin/activin ligand trap for muscle-wasting disorders. Clinical development was HALTED in 2011 after unexpected vascular adverse events (epistaxis, telangiectasia) attributed to off-target BMP-9/10 inhibition. NOT FDA-approved; all further development was terminated. Now sold only as a grey-market research chemical. WADA-prohibited (myostatin inhibitor).

How are ACE-031 prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
Phase 2 in ambulatory boys with Duchenne muscular dystrophy was terminated early in 2011 after unexpected nose-bleeds and telangiectasia were observed (attributed to off-target BMP-9/10 neutralization); published results later showed no significant 6MWT benefit vs. placebo in the truncated trial (Campbell et al., Muscle & Nerve, 2017; PMID 27462804). A single-ascending-dose Phase 1 study in healthy postmenopausal women (Attie et al., Muscle & Nerve, 2013; PMID 23169607) showed dose-dependent modest lean-mass increase but also the same vascular signal. Acceleron formally discontinued ACE-031 in 2013 and pivoted to other ActRII programs. No FDA approval; development TERMINATED for vascular safety. WADA-prohibited.
