From my experience folks often mention those peptides like PT-141 or the melanotan types yet most women dislike the unwanted effects and results differ a lot sometimes offering nothing at all. TRT isn't a peptide but it works best to raise sex drive and at her stage in life she probably could use it. Her blood tests would show if that's true and guide any decisions regarding hormone replacement.
My spouse has hit her fifties. Any info on whether peptides can raise libido levels among older females?
