Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
The conversation discusses GT20029, a drug in Phase II trials that targets androgen receptors with minimal systemic effects, and TDM-105795, a growth stimulant with a different mechanism than minoxidil that may revive papilla stem cells. Both are potential new treatments for hair loss.
