About TB-500 10mg
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring 43-amino acid peptide found in virtually every cell of the human body. It plays a crucial role in cell building, migration, and differentiation — essentially the master regulator of cell repair. TB-500 has a remarkable systemic reach, meaning it travels throughout the body to find and repair damaged tissue wherever it is needed. Those dealing with chronic inflammation, joint stiffness, injury recovery, or reduced mobility find TB-500 to be exceptionally effective. It promotes flexibility and elasticity in tissues, reduces scar tissue formation, restores movement in fibrotic areas, and supports cardiovascular tissue health. Many users also report improved hair thickness and accelerated wound healing as secondary benefits.

Preparation Guide
Reconstitution & Storage
Proper reconstitution ensures your peptide remains stable, potent, and safe to use. Follow these steps carefully each time you prepare a new vial.
BAC Water to Add
2 mL
Resulting Concentration
5 mg/mL
Typical Dose Volume
0.4 – 1.6 mL per dose (2–8 mg)
Shelf Life After Reconstitution
28 days
Step-by-Step Reconstitution
Wash & Prep
Wash hands thoroughly with soap and water. Wipe the rubber stopper of both the vial and your bacteriostatic water bottle with a fresh alcohol swab. Allow to air-dry for 30 seconds.
Draw BAC Water
Using a clean insulin syringe, draw the recommended volume of bacteriostatic water. Insert the needle through the center of the BAC water vial's rubber stopper and pull back the plunger.
Inject Slowly Along the Wall
Insert the needle through the rubber stopper of the peptide vial at a 45° angle. Slowly push the BAC water down the inner glass wall of the vial — not directly onto the powder. This prevents frothing and denaturation.
Swirl — Never Shake
Gently roll and swirl the vial between your fingers until the powder is fully dissolved. Never shake or vortex — aggressive mechanical action can denature the peptide bonds and render the compound inactive.
Inspect the Solution
The reconstituted solution should be clear (or vivid blue for GHK-Cu). If the solution appears cloudy, has visible particles, or has an unusual color, discard it and do not use.
Label & Refrigerate
Write today's date on the vial. Store immediately in the refrigerator at 2–8°C. Never leave reconstituted peptides at room temperature for extended periods.
Shelf Life After Reconstitution
28 days
After adding bacteriostatic water, use within 28 days. Always write the reconstitution date on the vial. Discard any unused solution after this period.
Sealed Vial Storage
Up to 24 months (sealed, room temp)
Room temperature (15–25°C), away from light and heat
After Reconstitution
Refrigerate at 2–8°C
Refrigerate at 2–8°C. Do not freeze. Keep capped and upright.
Product Notes
Loading phase: 4–8 mg/week split into 2 injections. Maintenance: 2–4 mg bi-weekly. Can be combined in same syringe with BPC-157.
Never shake the vial. Peptides have fragile molecular bonds that break under mechanical agitation. Shaking causes denaturation and can make the compound inactive. Always swirl gently.

“I can move freely again”
After 3 years of hip stiffness and reduced mobility, 8 weeks of TB-500 has transformed how I move. My PT is genuinely shocked by my progress. This compound does exactly what the research suggests.

“Stacking BPC-157 + TB-500 is the golden duo”
I run these together for my recovery protocol and the synergy is incredible. Old tendon injury that never fully healed has finally started responding. 12 weeks in and I'm back to full training. Rejuven's quality is excellent.

“Gradual but lasting results”
TB-500 works over time — this isn't a one-week fix. By week 4 I noticed real flexibility improvements. By week 8 the chronic shoulder inflammation was dramatically reduced. Stick with it.
