IGF-1 DES
Summary
Melanotan 1 (Afamelanotide) is a synthetic analog of α-MSH that selectively stimulates melanogenesis (tanning) through MC1R activation. It provides UV-independent skin pigmentation and is FDA/EMA-approved under the name SCENESSE for erythropoietic protoporphyria (EPP) and vitiligo.
IGF-1 DES (also written DES(1-3)IGF-1) is a truncated form of IGF-1 missing the first three amino acids of the N-terminus. This structural change dramatically reduces its affinity for IGF binding proteins (IGFBPs), meaning a far greater fraction remains in its free, active form. IGF-1 DES is estimated to be 10x more potent than standard IGF-1 LR3 at the receptor level locally, making it particularly effective for site-specific muscle growth when injected intramuscularly.
Half-Life
~40–60 minutes (free peptide); implant formulation (SCENESSE) releases over months
~20–30 minutes (very short — designed for local action)

0.5–1 mg
20–50 mcg per injection site
Frequency
Daily until desired color achieved, then maintenance
Once daily, post-workout
Key Benefits
  • Induces skin pigmentation/tanning without UV exposure
  • Provides photoprotection in photosensitivity conditions (EPP)
  • FDA-approved for erythropoietic protoporphyria (SCENESSE)
  • Approved in EU for EPP treatment
  • Anti-inflammatory via MC1R
  • Mild libido enhancement
  • Potential skin cancer prevention through melanin protection
  • Estimated 10x greater potency at the receptor vs IGF-1 LR3 locally
  • Minimal IGFBP binding — nearly all active upon injection
  • Highly localized muscle growth effect when injected intramuscularly
  • Activates satellite cells for muscle fiber hyperplasia potential
  • Synergistic with GH peptides in post-workout anabolic protocols
  • Shorter half-life reduces systemic exposure vs IGF-1 LR3
  • Useful for site-specific muscle development
Side Effects
  • Nausea (especially at higher doses)
  • Facial flushing
  • Fatigue
  • Injection site reactions
  • +3 more
  • Hypoglycemia (most significant risk — especially post-workout)
  • Localized muscle swelling at injection site
  • Potential for jaw/organ growth (acromegalic effects) with prolonged high-dose use
