TB-500 vs Kisspeptin-10
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
TB-500
Thymosin Beta-4 (TB-500) is a naturally occurring peptide present in almost all human and animal cells. It plays a crucial role in tissue repair and regeneration.
Full details →Kisspeptin-10
Kisspeptin-10 is the active fragment of kisspeptin, a hormone that plays a crucial role in initiating puberty and regulating reproductive function. It acts upstream of GnRH in the hypothalamic-pituitary-gonadal axis.

| Aspect | TB-500 | Kisspeptin-10 |
|---|---|---|
| Mechanism | TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing. | Binds to KISS1R receptors in the hypothalamus, stimulating GnRH neurons to release GnRH. This triggers the downstream cascade of LH, FSH, and sex hormone production. |
| Typical Dosage | Research protocols typically use 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks. | Research protocols vary widely. Studies have used IV boluses of 1-10mcg/kg or subcutaneous administration. Clinical applications still being developed. |
| Administration | Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites. | IV or subcutaneous injection. Has very short half-life requiring frequent administration or continuous infusion for sustained effects. |
| Side Effects | May cause temporary fatigue, headache, or localized irritation at injection sites. | Limited data. May cause flushing, increased heart rate, and changes in libido. Generally well-tolerated in studies. |
