About X-23

X-23 is a blend of BPC-157, TB-500, and NAD+, supplied as a compounded preparation. Combining them in one preparation means one injection instead of 3.

In published research, these compounds have been studied for tendon & ligament repair, gut healing, muscle recovery, soft-tissue recovery, and reduced inflammation. Research interest is not proof of benefit, and individual results vary.

It is a prescription therapy: a licensed provider reviews every order before it ships.

What is in it

BPC-157

BPC-157 ("Body Protection Compound") is a 15-amino-acid peptide derived from a protein found in gastric juice. It is one of the most-studied peptides in tissue-repair research — tendon, ligament, muscle, and gut models — and the most common starting point for people new to peptide therapy.

TB-500

TB-500 is a synthetic fragment of thymosin beta-4, a protein involved in cell migration and wound healing. It is studied for soft-tissue recovery and is frequently paired with BPC-157 — G1's Wolverine pen combines the two.

NAD+

Nicotinamide adenine dinucleotide is a coenzyme in every cell, central to energy metabolism and DNA repair. Injectable NAD+ is used in longevity and recovery protocols because oral forms are poorly absorbed.
