Melanocyte stimulating hormone (MSH) is a peptide hormone. That means it is
made out of amino acids. It is very similar
to the stress hormones ACTH and POMC.
MSH has many functions, some of which are only recently being described. It is
an ancient peptide hormone, and is found in many different types of animals.
MSH, like the name implies, does have a role in skin darkening, or pigmentation.
For a good description see:
Some steroid/thyroid hormones can stimulate the production of MSH- which then
stimulates melanocyte proliferation and melanin production.

MSH is not solely used in pigmentation. It has a role in the immune system,
including anti-inflammatory and antimicrobial effects. It may have a role in
recovery from nervous system injury, and it has cardiovascular and behavioral
The hormone primarily responsible for male secondary characteristics, such as a
deepening voice and body hair, is testosterone. (It is an anabolic steroid.)
I do not know if MSH is available as a drug. I would caution you against using
any medication without the advice of a medical professional. Hormones have wide
ranging effects on the body, and can range from ineffective to beneficial to
dangerous when consumed. Believe me, we don't know much about how these
substances work! So, be careful. A tan might be nice, but side-effects and long
term effects might not be.
