Research, mechanism, dosing, and effectiveness of Thymosin Beta-4 for hair growth.
Quick Answer
TB4 may support hair growth.
Evidence Level
Human Trials
Typical Dose
2-5 mg weekly
Results Timeline
Hair effects over 3-6 months

How Thymosin Beta-4 Works for Hair Growth
Promotes blood flow and cell migration to follicles.
About Hair Growth
Stimulation of hair follicles and prevention of hair loss.
Research Evidence
Extensive research on wound healing, cardiac repair, and tissue regeneration. Studies show TB-4 accelerates dermal wound closure and promotes corneal epithelial healing. Research in cardiac repair shows improved outcomes post-myocardial infarction in animal models. The shorter half-life means more frequent dosing compared to TB-500.
Dosing for Hair Growth
Recommended Dose
2-5 mg weekly
Frequency
2-3x weekly
Administration
Subcutaneous injection, topical for eye conditions
Duration
4-8 weeks typical protocol
Note: Full 43-amino acid protein (not TB-500 fragment). Similar uses but shorter half-life. Often confused with TB-500 in marketplace.
What to Expect
Initial adjustment period. Some users may notice subtle changes.
Early benefits often become noticeable. Continue consistent use.
Most users report meaningful improvements by this point.
Full effects typically realized. Reassess and adjust as needed.
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •Generally well-tolerated
- •Injection site reactions
- •Headache
- •Fatigue
- •May trigger histamine release - use caution with MCAS or histamine sensitivity
- •Theoretical concern for cancer cell motility

Other Peptides for Hair Growth
These peptides are also researched for hair growth.
TB-500
PreclinicalA synthetic 17-amino acid fragment of Thymosin Beta-4 (TB-4). Unlike TB-4, TB-500 has a longer half-life (~2-4 days vs ~2 hours) and is the active region responsible for tissue repair and cell migration. Note: Many vendors mislabel TB-4 as 'TB-500' in premixed products.
BPC-157
PreclinicalA synthetic peptide derived from a protein found in human gastric juice. Known for its remarkable tissue healing properties across multiple body systems. FDA classified as Category 2 in 2023, restricting compounding.
Pentadecapeptide
PreclinicalThe full 15-amino acid sequence that includes BPC-157. While BPC-157 is more commonly discussed, the full pentadecapeptide has similar healing properties derived from gastric juice.
Ziconotide
FDAA synthetic cone snail venom peptide for severe chronic pain. The first intrathecal non-opioid analgesic FDA approved.
