What is Melanotan 2?
Synthetic analog of α-MSH (alpha-melanocyte-stimulating hormone). Acts on melanocortin receptors throughout the body.
Experts on background and overview · 5 cited mentions
"What's the starting dose for me too? I don't want to get crazy tan. I think 0.1 milligram. Some guys start low, 0.1 milligram to assess tolerance, then 0.25, 0.5, then 1 milligram, keep on 1 milligram for a while and then drop back down to 0.1 milligram maintenance."
"Considering somebody is taking melanotan two and retatrutide, would either one of those because of vertigo or the feeling of low blood sugar... melanotan can make you a little bit nauseous, and retatrutide can give you low blood sugar."
"I think that melanitan one actually is just kind of inferior to MT2 in every way... MT2 is like the godfather of everything. It does all things."

"You've probably seen when people take too much melanotan, that will completely give someone an aged look."
"I had another girl sent me a picture of a huge rash on her arm from Melanotan 2."
How does Melanotan 2 work?
Non-selective melanocortin receptor agonist (MC1R = tanning, MC3R/MC4R = appetite/sexual/mood). MT2 is broader than MT1 (tanning-only) and PT-141 (sexual-only).
Mechanism note
These mechanisms are presented as research observations and hypotheses from the indexed data, not as confirmation of clinical effect in humans.
What is Melanotan 2 researched for?
Tans the skin (pigmentation), enhances libido and sexual function, mood elevation, mild appetite suppression. Tanner calls it his 'number one favorite peptide of all time.'

"Melanitan is actually studied on a model of autism in rats. So, it showed that it reduced autistic behavior... I've had a lot of guys come back to me and say, 'I'm way better at detecting social cues. I register sarcasm better. Conversation flows better with strangers.'"
Melanotan 2 Dosing Protocols
The entries below are transcript-derived dosing mentions. They are preserved for research context and are not medical advice.
| Speaker | Source | Timestamp | Protocol | Evidence |
|---|---|---|---|---|
| Vigorous Steve | Trenbolone’s Minimum Dose, Generic GH Gone, SS-31 Effective Dose,... | 01:25:34 | Steve reported an anecdotal ramp protocol: starting at 0.1 mg, increasing to 0.25 mg, then 0.5 mg, then 1 mg until desired tan was achieved, followed by maintenance at 0.1 mg. Reported for educational purposes only; not medical advice. | anecdotal |
| Andrew | How Coaches Perfect a Carb Load - The Most Important Skill in Bodybuilding | 00:37:33 | Andrew reported using a protocol of 5 days at 500 mcg, then dropping to 250 mcg, with the option to return to 500 mcg if not dark enough; he noted 250-500 mcg as a sufficient dosing range. | anecdotal |
| Tanner Tattered | Tanner Tattered: Peptides & Drugs for Long-term Bodybuilding Success | 01:29:31 | Subcutaneous, low-dose ramp-up. Tanner combines with PE-22-28 for mood. Antihistamine taken before injection helps reduce nausea side effect. | anecdotal |
| Scott | How Coaches Perfect a Carb Load - The Most Important Skill in Bodybuilding | 00:36:54 | Scott reported an old-school loading protocol: 1 mg/day every day until desired tan, then 1 mg twice per week for maintenance | anecdotal |
| Tanner / Nyle Nayga | Tanner Tattered: Peptides & Drugs for Long-term Bodybuilding Success | 01:29:31 | Pre-dose with antihistamine a few minutes before injection to blunt face-flushing; use ondansetron (Zofran) to manage nausea. | anecdotal |
