Hey bigtyivier, what's the current goal? Appreciate the details & expectations (from a veteran user)* 8)
How many administrations did it take to reach 5mg on the new melanotan vial? Any base tan present? UVR Exposure at all during the week?
One-half of a Melanotan 2 vial, in one week, would generally be very aggressive - can certainly understand the concern - do you find yourself to be sensitive to the product or experience side effects?
Given the days required to develop melanin pigment at the cellular level, I think another week should be enough to notice change - best of luck!
