New and improved TB4-Frag\u2122 Oral Spray in a refreshing peppermint flavor. This advanced formulation delivers 250 mcg of the active fragment of Thymosin Beta 4, a peptide known for its role in supporting a healthy immune system.
Updated formula is both alcohol and sugar-free, utilizing stevia extract and organic peppermint essential oil for a cleaner, more natural taste.
Additionally, each serving includes 25 mg of D-Ribose, a naturally occurring sugar that aids in stimulating mitochondrial function, thereby promoting energy production at the cellular level. Designed for ease of use, the oral spray format offers a convenient alternative to injections, making it simple to incorporate into your daily routine.

How to use:
- Spray twice into the mouth, twice per day, or as recommended by your healthcare provider.

Gastrically stable, can be taken with or without food. Some reports, however, indicate that absorption for supplements are better on an empty stomach.
