Melanotan 1 protocol: Frequently asked questions

Reduce the current dose by 50% immediately and recheck blood pressure in 48 hours. If systolic exceeds 150mmHg or diastolic exceeds 95mmHg, discontinue entirely and consult your physician before resuming. MC4R-mediated vasoconstriction resolves within 36–48 hours of stopping the peptide, so elevated readings should normalize quickly if they were peptide-induced rather than undiagnosed hypertension.

Melanocyte density declines with age, so pigment accumulation takes longer in older adults even at therapeutic doses. Visible tanning in individuals over 50 typically requires 28–42 days of consistent dosing. Twice the timeline younger users experience. Increasing dose beyond 0.75mg daily to speed results carries cardiovascular risk that outweighs cosmetic benefit. Patience is the correct response, not dose escalation.

Persistent gastrointestinal side effects at the lowest effective dose indicate MC4R sensitivity that won't improve with continued dosing. Reduce to 0.125mg daily (every other day dosing at 0.25mg) or discontinue. Melanotan-1 isn't appropriate for all individuals. Forcing tolerance through persistent nausea degrades quality of life without meaningful benefit.

Melanotan-1 use with baseline hypertension requires physician oversight and should not proceed without clearance. If your hypertension is well-controlled (consistently <130/80mmHg on medication), a modified protocol starting at 0.125mg daily with weekly blood pressure monitoring may be safe. Uncontrolled hypertension (>140/90mmHg) is an absolute contraindication. MC4R stimulation will worsen existing vascular strain.

Melanocyte MC1R receptors downregulate with sustained agonist exposure. A protective mechanism against overstimulation. The solution isn't higher doses; it's cycling off for 7–10 days to allow receptor resensitisation, then resuming at the original dose. Melanin produced during the initial cycle persists for weeks, and the break prevents tolerance buildup. Our research teams consistently observe better long-term tanning maintenance with 3-week-on/10-day-off cycles than with continuous daily protocols.

Nausea from melanotan-1 is mediated by alpha-MSH activation of MC4R receptors in the hypothalamus, which overlap with appetite regulation pathways. Administering the peptide with a small amount of fat (10–15g, such as a tablespoon of coconut oil or a few nuts) 30 minutes before injection blunts the nausea response without significantly impairing absorption. Avoid full meals, but strategic fat intake raises ghrelin enough to counteract MC4R-mediated nausea.

Skip the dose for that day rather than injecting late and mistiming the UV window. Melanotan-1 is not cumulative in the sense that missed doses can be 'made up'. Melanocyte activation is time-locked to UV exposure, and a late injection without corresponding UV produces no tanning benefit while still causing side effects. Resume your normal schedule the following morning.

The dose is largely wasted. Plasma peptide levels drop below melanogenic threshold after 3–4 hours, and melanocytes require concurrent alpha-MSH signalling and UV-induced DNA damage to activate tyrosinase pathways. Injecting without UV produces minimal melanin synthesis. Don't double-dose the next day to compensate; simply return to standard protocol.
