How It Works
ACE-031 is a recombinant fusion protein that acts as a decoy receptor for myostatin and other TGF-β superfamily ligands. By binding these ligands, it prevents them from activating their natural receptors, removing the "brakes" on muscle growth. This results in increased muscle fiber size and number without requiring additional exercise stimulus.
Reconstitution Guide
Follow these steps to properly reconstitute ACE-031 for research use:
- Step 1: Swab the tops of both the peptide vial and bacteriostatic water vial with alcohol.
- Step 2: Draw your desired amount of BAC water (commonly 1–2 mL) into an insulin syringe.
- Step 3: Inject the water slowly into the peptide vial, aiming at the glass wall — not directly onto the powder.
- Step 4: Swirl the vial gently until fully dissolved — never shake.
- Step 5: Refrigerate at 36–46°F (2–8°C). Use within 4–6 weeks.
Use the dosing calculator to calculate your exact concentration (mcg per unit) and how many units to draw on your syringe.
Frequently Asked Questions
How does ACE-031 work? ▾
ACE-031 is a recombinant fusion protein that acts as a decoy receptor for myostatin and other TGF-β superfamily ligands. By binding these ligands, it prevents them from activating their natural receptors, removing the "brakes" on muscle growth. This results in increased muscle fiber size and number without requiring additional exercise stimulus.
What are the key research findings? ▾
- Significant increases in lean muscle mass observed in clinical studies
- Reduces body fat percentage through enhanced metabolic activity
- Originally studied for Duchenne muscular dystrophy (trials paused due to safety concerns)
- Blocks multiple negative regulators of muscle growth beyond just myostatin
What is the typical dosing protocol? ▾
ACE-031 is typically administered subcutaneously once every two weeks. Dosing in clinical trials ranged from 0.25–3 mg/kg. This is an advanced research compound — consult the latest literature and proceed with caution given the limited human safety data.
How should ACE-031 be stored? ▾
Unreconstituted powder should be stored in a freezer or refrigerator away from light and moisture. Once reconstituted with bacteriostatic water, refrigerate at 36–46°F (2–8°C) and use within 4–6 weeks. Never freeze reconstituted peptides.
