Side-by-Side Comparison

AspectTB-500Kisspeptin-10
MechanismTB-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 DosageResearch 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.
AdministrationAdministered 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 EffectsMay 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.
