Identity
MT-2 is short for Melanotan II, a lab-made peptide built to mimic a hormone the pituitary gland makes called alpha-melanocyte-stimulating hormone. Researchers at the University of Arizona designed it in the 1980s as a sunless-tanning candidate, the idea being that it switches on the same skin-pigment machinery a day outdoors does. It is also the parent molecule that a smaller fragment, PT-141, was later cut from.
MT-2 is a laboratory reference material. SBz Industries sells it for laboratory research.
Research
In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.
Melanotan II has a real but dated human research record: a few small studies in the 1990s with a handful of volunteers, mostly measuring skin color. Almost nothing formal has been published since, so most of what is known about how it is used today comes from studies of online forum posts rather than controlled trials.
people1996
Gave repeated injections to three healthy men over two weeks and tracked skin color, blood pressure, and side effects like nausea and sleepiness. Researchers measured visibly increased pigmentation in the face and upper body about a week after the injections stopped.

Read through 623 posts from 205 people on UK and Ireland online forums discussing their own use of the peptide and grouped the recurring themes. The researchers found wide variation in how people prepared and used it, and flagged concerns like unclear product sourcing, separate from anything tested in a formal trial.

Handling
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
Slowly, down the inside wall of the vial, never straight onto the powder.
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.
Documentation
An independent lab tests every compound we sell. It confirms the compound is what the label says and measures purity by HPLC.
The latest certificate is on the product page, so you can read the result before you order.

No, but they are related. PT-141 is a smaller fragment cut from the Melanotan II structure that acts on a more specific set of receptors.
A handful of small studies from the 1990s covering a few dozen people in total, mostly measuring skin color. Almost nothing formal has been published since.
MT-2 ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.
Store as stated on the product page and the certificate of analysis. Vials ship in plain outer packaging with no product name on the outside.
Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.
Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
