- First-time users, dose-finding, high sensitivity to MC4 agonists
- Threshold dose. Minimal but measurable effect. Good starting point for titration.
- 1.0–1.25mg
- 30–60 minutes
- 6–8 hours
- 30–40%
- Standard therapeutic range for most adults
- Sweet spot for libido enhancement with manageable side effects. Most research protocols target this range.
- 1.5–1.75mg
- 30–50 minutes
- 50–60%
- High receptor threshold individuals, non-responders at lower doses
- FDA-approved dose for women (Vyleesi). Effective but nausea limits repeat use for many.
- 2.0mg+
- 25–45 minutes
- 65–75%
- Rarely justified. Side effects exceed benefit
- Ceiling dose. No additional libido enhancement beyond 1.75mg, but nausea becomes prohibitive.
- PT-141 doses above 2mg do not produce proportional increases in sexual desire or arousal. The melanocortin receptors governing libido reach saturation between 1.5–1.75mg. Higher doses simply activate more off-target MC4 receptors in nausea centres without enhancing therapeutic effect.
