I haven't observed that effect - but I've only dosed three times and usually about 3 weeks apart. Any compound that mimicks or stimulates MSH production could cause a change in pigmentation (as you are well aware). There is also a correlation between estrogens, MSH and hyperpigmentation which has left me wondering if anabolic users may see some hyperpigmentation if E levels weren't kept in check.

I've read conflicting reports about whether Bremelanotide/PT-141 will cause changes in pigmentation (and that was its original intended application) or if its been modified solely for libido enhancing effects.

Maybe I should increase my dose frequency? Then I could avoid the sunless tanning sprays guys use for BB shows and get the added benefit of libido enhancement (I'm sure my wife will be thrilled at that prospect!)
