Melanotan I

Melanotan I, or MT-1, is a peptide people discuss for gradually darker skin, often while trying to avoid Melanotan II’s nausea or sexual effects. Reports range from a natural-looking tan to little change and unpleasant flushing. Medical afamelanotide implants and unregulated tanning vials are different products.

A pigment signal, rather than a surface bronzer. Afamelanotide imitates alpha-MSH, a hormone, and mainly activates MC1R, which helps make the brown pigment eumelanin. DailyMed — SCENESSE prescribing information (Official context · Accessed 2026-09-30)

Community vials and the medical implant differ. SubQ means under the skin. SCENESSE is a medical implant for adult EPP, a painful light-sensitivity disorder. Community vials are different; nasal and topical MT-I are not established routes in the original record. DailyMed — SCENESSE prescribing information (Official context · Accessed 2026-09-30)

Color that looks like their own tan. Maceisalive described becoming very dark after 2.5–3 weeks at a reported 250 mcg per dose with five-minute tanning sessions three times weekly. The commenter liked the natural appearance and reported less total UV time than on a previous beach trip; that does not measure protection from skin damage. Reddit — Dosing?

A more pigment-focused experience than MT-II. Some choose MT-I to avoid nausea, erections or appetite changes associated with MT-II. Kush_McNuggz found color development slower, with barely noticeable change after one week at 100 mcg daily. Preference and slower onset do not establish comparative safety.

A week can bring little change; weeks can still bring none. Reports include subtle color retention at one week, strong color at 2.5–3 weeks, and no result near one month. One later discussion describes two weeks at 600 mcg/day without UV and no tan, followed by much darker exposed skin during a ten-day holiday.

Sun exposure keeps changing alongside the peptide. Some see color only after adding UV; others retain an earlier tan without further deliberate tanning. Looksmaxxing’s OP asks whether added sun explains success. These accounts do not establish a dependable sunless result. Reddit — Anyone here using Melanotan 1 (MT1)?

250 mcg per dose; frequency is not always stated. The successful 2.5–3-week account kept that amount through maintenance, but did not give injection frequency. Hick6262 separately reported 250 mcg daily for almost a month without a result, then 500 mcg daily with added tanning-bed sessions, and nausea after one 1 mg dose. Reddit — Dosing?

Chart amounts disagree with each other. Original charts include 50–100 mcg daily starts; 200 mcg/day for 1–2 weeks then 100 mcg 2–3 times weekly; 250 mcg loading then 1–2 weekly doses; and higher commercial-style claims of 1 mg/day for ten days then 2 mg/week. Wider 0.25–2 mg/day claims are separate lore, not a combined standard.

Per-injection and daily totals need separate labels. One Reddit reply promotes 250 mcg twice daily, totaling 500 mcg/day, versus later 500 mcg twice daily, totaling 1 mg/day. Other people report once-daily use. The thread’s challenged ‘300 mg’ entry cannot be silently converted into 300 mcg. These are descriptions, not instructions. Reddit — Melanotan-1 Protocol?

A 2.5 mg dose ended one experiment. After prior 500 mcg use, an author reported a red face, pounding heartbeat and exhaustion lasting most of the day. Their limited tan did not justify the discomfort to them. This is an adverse account, not the top of a useful-dose range.

One account kept color for weeks after stopping. MommaDee62 recalled roughly 250 mcg every other day over about three weeks, with tanning-bed exposure, then a Florida trip without continuing peptide. Color reportedly persisted for weeks; vacation sun and imprecise recall prevent isolating the drug’s contribution. Reddit — MT1 dosage guide (Community discussion · Accessed 2026-09-30)

Physical effects can last longer than the short-half-life shorthand. The high-dose author felt exhausted for most of a day; another reported stomach upset for an hour. There is no reliable single-dose ‘feel’ window or predictable fade time for cosmetic vials.

Historical injections had short measured clearance. Ugwu’s 1997 study in three men used 0.08–0.21 mg/kg SubQ over ten doses: absorption-phase half-lives 0.07–0.79 hours; elimination 0.8–1.7 hours. No drug was detected after oral dosing. Pigmentation persisted three weeks after the course. These human research-solution values do not validate cosmetic charts.

The implant has its own kinetics. SCENESSE’s 16-mg implant is administered every two months; its median peak is 36 hours and apparent half-life about 15 hours. UV-independent pigment production here does not establish cosmetic vial performance. DailyMed — SCENESSE prescribing information (Official context · Accessed 2026-09-30)

Loading-to-maintenance is a convention with sparse follow-up. Original notes describe daily or near-daily loading for 1–2-plus weeks, then 100–250 mcg per administration 1–3 times weekly across a season. The 250-mcg successful account continued its amount; Hick6262’s 250 mcg twice-weekly maintenance was only a plan. Reddit — Dosing?

Seasonal use does not prove a receptor-reset requirement. Summer or pre-vacation courses and an informal eight-weeks-on/eight-weeks-off pattern appear in the original record. Discussion focuses on color fade, cost, changing moles and tolerability rather than classic hormonal post-cycle therapy. No dependable mandatory off-cycle is established.

Skin care and nausea habits are part of the discussion. Original notes include moisturizer, SPF realism, mole photographs, lower-start claims, morning-versus-evening experiments, hydration and light food. These are reported habits, not demonstrated ways to make unregulated injections safe; anti-emetic stacks are not a central MT-I theme.

UV exposure alongside use: Community notes describe sun or tanning-bed sessions of roughly 10–30 minutes during loading, followed by less frequent exposure to maintain color. These are reported habits, not validated UV limits or evidence that every user needs the same exposure. [community]

Skin-care adjacency: Moisturizer, realistic SPF habits, and mole photography/monitoring discussed more than second peptides. [community]

Price and frequent injections affect preference. Original lore says MT-I needs more peptide, sometimes ‘twice as much,’ as MT-II; that is not a dose-equivalence study. People debate switching versus combining them. The original record also mentions PT-141, GHK-Cu, astaxanthin and vitamin C, without verified synergy.

Compared with Melanotan II: Some discussions favor switching over combining MT-I and MT-II, citing unwanted effects without proportional pigment gain. That preference does not establish a dose-equivalence rule or comparative safety. [community]

Compared with PT-141: PT-141 appears in libido-focused discussions. The original notes describe MT-I/PT-141 combinations as uncommon and raise overlapping nausea and blood-pressure concerns without evidence of added benefit. [community]

Antioxidant / “photoprotection support” mentions: Occasional astaxanthin or vitamin C talk in blog stacks — confounded lifestyle add-ons, not validated MT-I potentiators. [community]

GHK-Cu or other skin peptides (minority): Occasional multi-peptide cosmetic stacks; attribution of tone changes becomes muddied. [community]

Freckles and moles can darken too. The label calls for twice-yearly skin examinations and continued light protection. Changing lesions need professional assessment. Darkening neither proves cancer nor makes a tan sunscreen. DailyMed — SCENESSE prescribing information (Official context · Accessed 2026-09-30)

‘Side-effect-free’ is contradicted by experience. A Looksmaxxing reply claims this from receptor selectivity. Reports of nausea, flushing and marked exhaustion contradict it. Unwanted effects also cannot identify what an unverified vial contains.
