A combination stack using Melanotan II for tanning and libido effects with PT-141 (Bremelanotide) for targeted sexual enhancement. Both work on melanocortin receptors but can be used together for comprehensive effects.
Quickstart Highlights
- Dosage: 0.25-0.5mg MT2 + 1-2mg PT-141
- Frequency: MT2: loading then maintenance. PT-141: as needed
- Administration: Subcutaneous injection or nasal spray
- Cycle length: MT2: 4-6 weeks loading. PT-141: as needed
Dosing Plan
| Weeks | Dose | Units |
|---|---|---|
| MT2 Loading | 0.25-0.5mg daily with UV exposure | 4-6 weeks |
| MT2 Maintenance | 0.5mg 1-2x weekly | After desired tan achieved |
| PT-141 As Needed | 1-2mg 2-4 hours before activity | No more than 1x per 24 hours |
How This Works
Melanotan II activates MC1R (for tanning/melanogenesis) and MC3R/MC4R (for libido/appetite). PT-141 is more selective for MC3R/MC4R, providing sexual enhancement without as much tanning effect. Using both allows optimization of tanning (MT2) with on-demand sexual enhancement (PT-141). They work centrally in the brain to enhance arousal and desire.

Reviews & Discussion
Real experiences shared by the community — not medical advice.
Synergistic Libido and Tanning Effects of MT-II and PT-141 Stack
A user reported that combining Melanotan II with PT-141 significantly increased the intensity of the physiological effects compared to using either alone. They noted a substantial increase in libido and tanning speed, though they cautioned about the potential for increased side effects such as nausea and facial flushing.
Libido Support and Digestive Side Effects with MT-II/PT-141 Stack
A user shared their experience using PT-141 alongside low doses of Melanotan II, finding it effective for libido enhancement but experiencing moderate 'stomach tightness' and nausea shortly after administration. They recommended starting with very low doses to assess tolerance due to the potency of the stack.
Increased Libido and Performance Synergy
A user described experiencing strong, persistent erections and increased sexual drive when using a combination of Melanotan II and PT-141. They mentioned that while Melanotan II provided tanning and some libido benefits, PT-141 was specifically potent for arousal. Some mild flushing was noted as a side effect shortly after administration.
Synergistic Sexual Benefits of MT-II and PT-141
A user reported that stacking Melanotan II and PT-141 provided a significant boost to their libido and sexual performance. They noted that Melanotan II by itself already increased libido, but adding PT-141 amplified the effect considerably. The user stated the combination was highly effective for enhancing sexual desire and erection quality.
Melanotan II Dose for Flatlined Libido
A user planning to use Melanotan II for flatlined libido reported starting with a 300 mcg test dose to avoid severe nausea and vomiting. They expressed hope that it would improve physical function despite concerns about potential gastrointestinal side effects.
Melanotan II Efficacy and Side Effects
A member warned that Melanotan II is ineffective for increasing libido and is notorious for causing bad belly cramps and nausea. They noted it only provides temporary erections without addressing underlying sexual desire.
Melanotan II for Erection Strength
A user recommended Melanotan II as part of a performance stack for improving erection strength and frequency. They suggested it works well when combined with other supplements like Clomid or HCGen.
PT-141 and TRT Synergy for Libido
A user reported significant success using PT-141 for libido and erectile function while on TRT. Following a 1.25 mg dose, they experienced a dramatic climb in libido peaking at five hours and lasting for 13 hours, including intense morning arousal.
Melanotan II for Libido and Appetite Suppression
A user testing Melanotan II for libido enhancement reported initial side effects of nausea and facial flushing within minutes of a 0.5 mg dose. While they noted excellent appetite suppression and a minor 15% boost in libido, they did not experience the spontaneous erections typically reported by others.
PT-141 for Psychological Libido Boost
A user noted that while Trimix helps with physical performance, PT-141 is uniquely effective for increasing sexual urge and desire. They indicated that PT-141 provides a mental libido boost that testosterone and other treatments sometimes fail to provide.
Melanotan II for Libido Support
A user recommended Melanotan II as an effective non-steroidal option for improving erections and libido. Another participant noted that PT-141 serves as the isolated component of Melanotan II specifically responsible for these sexual benefits.
PT-141 and Oxytocin Stack
One individual reported that stacking PT-141 with a small amount of oxytocin produced excellent results. They noted that this combination significantly improved sexual performance and satisfaction for both themselves and their partner.

Libido Comparison: PT-141 vs. MT2

Melanotan II Dosing Error Side Effects
A user reported experiencing negative side effects due to taking an excessive dose of Melanotan II. They noted that they failed to follow a proper titration protocol, which typically suggests starting at 250mcg before gradually ramping up.
Usage Distinction Between PT-141 and MT2
A user discussed the specific uses of each peptide, noting that PT-141 is intended for libido enhancement rather than tanning. They cautioned that PT-141 should not be used more than eight times per month, whereas Melanotan variants are the appropriate choice for skin pigmentation.
