Episode notes
Start With Full Hormone Optimization
- Consider a complete hormone protocol before assuming peptides are needed.
- Dr. Valerie Phillips routinely uses estradiol, progesterone, pregnenolone, DHEA and tailors doses to symptoms and tolerability.
PT-141 Acts Through Melanocortin Pathways
- PT-141 (bremelanotide) is a melanocortin fragment with central libido effects plus weight-loss and tanning actions.
- It stimulates the proopiomelanocortin system, affecting ACTH, endorphins and melanocyte stimulating hormones.
Manage PT-141 Side Effects With Dose Adjustment
- Watch for nausea and cramping with PT-141 and adjust dose rather than stopping immediately.
- Dr. Kent Holtorf and Dr. Valerie note side effects often lessen after initial doses and dose flexibility helps tolerability.
