Status
Approved for specific uses

Approved uses exist, but dose, formulation, device and monitoring are product- and indication-specific. A community table cannot replace the prescribing information or a prescription.

Schedule explained in detailApproved medicine

Amount status

SCENESSE label: one 16 mg implant every two months, exclusively for adults with erythropoietic protoporphyria.

Profile evidence level: established.

Timing

The implant is inserted by trained medical staff; it is not an injectable community vial.

No individual recommendation.

Cycle/duration

Repeat administration follows the approved indication and prescribing information, not a tanning cycle.

No individual recommendation.

Mixing & calculations

No. An implant is not dissolved in water.

All preparation informationProduct details and calculation examples from the available sources.

SCENESSE is a controlled-release implant. It is not reconstituted; unregulated 'Melanotan I' vials or sprays are not the same product.

Reconstitution & quantitiesOpen basics, units and sources
Explained in very simple termsBefore reading any number: this page reports what a product label, study or online community states. It does not say what any person should use.

Amount

mg or µg describe the mass of a substance. That is not the same as ml of fluid or U on a syringe. The number is only the amount stated by the identified source.

Interval

The interval only describes the time stated between two points. For example, once every 7 days does not mean daily and never justifies catching up or doubling.

Cycle

A cycle is a stated period that may include breaks. A community cycle proves neither effectiveness nor safety and does not prevent long-term risks.

Reconstitution

Reconstitution means mixing powder with a defined volume of fluid. This changes concentration, not the total amount in the vial. On U-100, 100 U equals exactly 1 ml of volume.

Not a guide to misuse

All community figures are shown only to place widely circulated online protocols in context. They are not instructions for self-use, injection, performance enhancement or any other misuse. Approved figures apply only to the exact named product, approved indication and medical supervision.

Research, risks & more detailsMechanism, adverse effects, storage, comparisons and common questions.

Mechanism: what is supported and what does not follow

Melanocortin-1 receptor agonist

Afamelanotide is classified as “Melanocortin-1 receptor agonist”. Promotes eumelanin production; approval is limited to a rare photosensitivity disorder. This describes the investigated pathway but does not validate a community use, amount, route or combination.

01

Melanocortin receptor activation

This studies how activating melanocortin receptors affects pigmentation or sexual arousal signals, like a switch controlling different body functions depending on the receptor subtype. Skin pigmentation or physiological arousal markers are measured in studies.

02

Pigmentation and light response

This studies how skin pigment cells respond to signals that darken skin, potentially reducing sensitivity to sunlight, similar to how a photograph darkens with more exposure. Researchers typically measure skin pigment levels and light sensitivity in study participants.

03

Reproductive hormone signalling

This examines effects on hormone axes influencing libido, cycle, or fertility, similar to a feedback loop connecting several glands. Hormone levels and subjective questionnaires are measured in studies.

What communities discuss

These themes describe discussions and vendor claims. They do not prove benefit, safety, product identity or suitable use.

Cosmetic procedure forums

Users compare tanning or skin changes after using melanocortin-related substances, often based on shared photos rather than medical examination. Such posts do not establish reviewed safety, especially for unapproved variants.

Source and purity discussion

Discussion covers which vendors are seen as more trustworthy and how purity test results differ between batches. Such community assessments are based on limited samples and do not replace independent lab testing of each individual batch.

General wellness forums

Broader wellbeing impressions such as mood, sleep, and general feeling after using various products are exchanged here, usually without structured tracking. Such general impressions are not a substitute for targeted clinical examination.

Adverse effects and safety risks

  • Melanocortin activity can cause nausea, flushing, blood-pressure changes, headache, unwanted pigmentation and sexual adverse effects; non-selective analogues add uncertainty.
  • Local reaction, infection, abscess and contamination are possible with any injection that is not professionally manufactured and administered.
  • A label or clear appearance does not exclude unknown purity, wrong identity, endotoxins or concentration errors.

Do not self-use / obtain clinical review

  • Atypical moles/skin-cancer risk, uncontrolled blood pressure, cardiovascular disease, priapism risk and pregnancy require medical assessment.
  • Acute symptoms, allergic reaction, breathing difficulty, chest pain, neurological deficits or severe abdominal pain require immediate medical care.
  • Children and adolescents, pregnancy/breastfeeding, and people with relevant disease should not be part of unsupervised experiments.

Monitoring and laboratory markers

  • Depending on the approved use, skin examination, blood pressure, nausea, pigment changes and indication-specific endpoints may be assessed.
  • Baseline, objective, measurement timing and stop criteria must be defined professionally in advance. Individual laboratory values cannot compensate for unknown product quality.

Evidence boundary

Established

Approval covers only the specific photosensitivity disorder.

Clinical evidence

The described biological role is well established, or extensive regulator-reviewed human data exist for clearly defined products and uses. This does not automatically transfer to other products or purposes.

Afamelanotide selectively targets the melanocortin-1 receptor and is approved for a rare disorder, unlike the non-selective, unapproved Melanotan II.

Storage and stability

  • Authentic SCENESSE implants are stored per the product information at 2–8 °C, protected from light.
  • Do not transfer this storage information to unidentified tanning products.

Troubleshooting and common errors

  • U-100 units measure volume, not drug amount: 100 U equals 1 mL. A wrong concentration makes every unit figure wrong.
  • Do not shake or dilute further to ‘fix’ cloudiness, particles or uncertain solubility; discard and obtain professional clarification.
  • Do not calculate a double or extra amount to compensate for missed use or an uncertain injection.
  • Without a COA, clear supplier, correct label and consistent vial information, identity is not confirmed.

Regulatory status and WADA

Approved for specific uses

Prescription active ingredient for defined indications in at least one jurisdiction; not offered here.

WADA 2026

The atlas has no explicit WADA flag for this profile. That does not automatically mean every form, route or related class is permitted in sport.

WADA — 2026 Prohibited List

Combinations / stacks

  • Combinations change effects, adverse effects and laboratory values; evidence for one substance does not establish the safety of a stack.
  • Overlapping pathways may add up. Hormonal, glucose, blood-pressure, coagulation, immune and sedating effects are important potential interactions.
  • Non-standardised blends prevent separate dosing, cause attribution and dependable reconstitution.

Frequently asked questions

Is an amount shown here a recommendation?

No. This page separates approved product information, study protocols and community information. No number or calculator is an individual dosing recommendation.

Does the U-100 calculator prove correct use?

No. It only converts mass, volume and syringe scale. It cannot check identity, purity, sterility, stability, solvent or medical suitability.

Can this profile be combined with other substances?

Safety of a combination cannot be inferred from a single-substance profile. Overlapping pathways, medicines and undefined blends can increase risk.

Which source controls when information conflicts?

For approved medicines, the current prescribing information and treating professional control. For research substances, conflict shows that no dependable self-use standard exists.

Are community claims clinical evidence?

No. Anecdotes can generate questions but do not replace controlled studies, regulatory review, or identity and quality testing.
