What did @dillon.latham actually say?
Dillon retells the story of a TikToker named Pear who used peptides including GHK-Cu, HGH, and Melanotan II (MT2) as part of a self-described "looks maxxing" experiment. Pear has since been diagnosed with melanoma, and Dillon says Pear himself believes MT2 "could be one of the causes that accelerated the cancer growth." The video frames this as a cautionary tale, not an endorsement, and it closes with a call for prayers rather than medical advice.
To be fair, Dillon does not tell viewers to use these compounds. He is reporting on someone else's situation. But the video still gives substantial airtime to an unverified personal theory about what caused a man's cancer, and 279,000 people watched it. That carries weight, regardless of intent.
Does the science back this up?
The Melanotan II and melanoma connection is not just Pear's hunch. There is real and concerning scientific literature here, even if causation is hard to prove in a single case. MT2 is a synthetic analog of alpha-melanocyte-stimulating hormone. It works by binding melanocortin receptors, which stimulate melanin production and, in doing so, can activate existing melanocytic lesions.
A 2014 case report published in the Journal of the American Academy of Dermatology (Dawson et al.) described melanoma transformation in a patient who used MT2 injections. A 2009 review in Clinical and Experimental Dermatology (Langan et al.) documented multiple cases of rapid nevi changes associated with MT2 use. The mechanism is plausible: MC1R signaling is already implicated in melanoma risk, and MT2 is a potent, non-selective agonist at those receptors. Add a family history of melanoma, which Pear reportedly has, and the biological concern compounds significantly. None of this proves MT2 caused Pear's cancer. But dismissing the association would be wrong.
What did they get wrong (or right)?
Dillon gets the core concern right: MT2 has a documented association with melanocytic changes and represents a serious, under-discussed risk. Credit where it is due.
Where it gets shakier is the framing of a personal anecdote as evidence. Pear used a "laundry list" of compounds. GHK-Cu, HGH, and MT2 all have different mechanisms. Attributing the cancer to MT2 specifically, even tentatively, is speculative. Melanoma is also strongly heritable. Pear's mother reportedly had the same condition, which means genetic predisposition is at least as plausible a primary driver as any peptide.
The video also uses the phrase "niche looks maxer" and frames this story partly through the lens of internet drama, which is a distraction from a genuinely serious pharmacological warning. When the signal is real, burying it in content about someone's incel past and viral moments does that signal a disservice. The information deserved a cleaner delivery.
What should you actually know?
Melanotan II is not approved by the FDA for any use. It is sold online, often unregulated, and sometimes mislabeled. It is not the same as licensed prescription treatments for skin conditions or sexual dysfunction. Anyone with a personal or family history of melanoma, dysplastic nevi, or other skin cancers should consider MT2 an especially high-risk compound.
- MT2 is distinct from peptides like GHK-Cu or BPC-157, which have different receptor profiles and different risk considerations. Grouping them all together as "peptides" understates how different the risk profiles are.
- If you have unusual moles, a history of sun sensitivity, or a family history of skin cancer, get a dermatology screening before using any melanocortin-pathway compound.
- A single case does not prove causation. But case reports in peer-reviewed literature, combined with a coherent mechanism, are exactly the kind of early signal that should make you cautious.
The bottom line: the fear around MT2 and melanoma is not irrational. It is supported by plausible biology and documented case reports. That does not mean every MT2 user will develop cancer. It means the risk is real enough that using it without medical supervision, especially with a relevant family history, is a genuinely bad idea.
