Side-by-Side Comparison

AspectMelanotan IIBPC-157
MechanismNon-selective melanocortin receptor agonist affecting MC1R (tanning), MC3R and MC4R (sexual function and appetite). This broader activity explains its multiple effects beyond tanning.BPC-157 works through multiple pathways including upregulation of growth factor expression, nitric oxide system modulation, and promotion of angiogenesis. It enhances tendon-to-bone healing and supports the formation of new blood vessels.
Typical DosageTypical protocols: 0.25-0.5mg daily during loading phase for 1-2 weeks, then 0.5-1mg before UV exposure for maintenance. Start low to assess tolerance.Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied.
AdministrationSubcutaneous injection. Usually combined with UV exposure for tanning effects. Nasal spray formulations exist but have lower bioavailability.Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable.
Side EffectsNausea (common initially), facial flushing, spontaneous erections, increased libido, appetite suppression, and mole darkening.Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses.
