Muscle Growth & Performance / Subcutaneous
Carnosine
Also known as β-Alanyl-L-histidine, L-Carnosine
A dipeptide of beta-alanine and histidine that acts as a buffer against lactic acid accumulation, enhancing muscle endurance and reducing fatigue.
What is Carnosine used for? Research has focused on buffers lactic acid accumulation during exercise; enhances muscle endurance and exercise capacity; reduces fatigue in high-intensity activities.

Side effects
| Effect | How often | Severity |
|---|---|---|
| Paresthesia (tingling sensation)Harmless tingling in the face, neck, or extremities, typically occurring 15-30 minutes after beta-alanine ingestion. Resolves within 1-2 hours. Not dangerous and does not indicate toxicity. Can be reduced by splitting doses or taking with food. | Common | Mild |
| Gastrointestinal discomfortMild nausea, bloating, or stomach upset may occur, particularly at higher doses or on an empty stomach. Taking carnosine with meals typically resolves this. | Uncommon | Mild |
| HeadacheOccasional mild headache reported in early supplementation. Usually resolves with continued use or dose reduction. | Rare | Mild |
| Flushing or facial rednessTransient facial flushing may occur alongside paresthesia. Not harmful and typically subsides within 1-2 hours. | Uncommon | Mild |

Reconstitution guide
- Do not use saline or bacteriostatic saline, use only bacteriostatic water for reconstitution
- Do not shake the vial vigorously; gentle swirling prevents peptide degradation
- Discard immediately if the solution appears cloudy, discolored, or contains visible particles
- Use within 30 days of reconstitution when stored at 2-8°C
- Do not freeze the reconstituted solution; freezing may denature the peptide
- Use the PeptideVolt reconstitution calculator for your exact concentration

Carnosine is a dipeptide composed of beta-alanine and histidine that functions as an intracellular buffer, reducing the accumulation of hydrogen ions (H+) and lactate during high-intensity exercise. By maintaining muscle pH, carnosine delays fatigue onset and supports sustained muscle force production. It also exhibits antioxidant and anti-glycation properties through its histidine moiety.
