Melanotan 2
Research description
Melanotan II (MT-II) is a synthetic cyclic heptapeptide engineered to act as a potent, non-selective agonist of the melanocortin peptide receptor family (MC1R, MC3R, MC4R, MC5R). Unlike the linear endogenous hormone $alpha$-MSH, Melanotan II utilizes a lactam bridge cyclization to enhance enzymatic stability and receptor binding affinity. It is supplied strictly for laboratory investigation into melanogenesis signaling, central nervous system (CNS) arousal pathways, and metabolic regulation.
Formerly classified in FDA 503A Category 2; removed from that list (effective April 22, 2026) following withdrawal of its nomination. This removal is a procedural step, not an FDA safety clearance — Melanotan II is still awaiting a future FDA Pharmacy Compounding Advisory Committee (PCAC) review (scheduled before end of February 2027) and has not been added to the 503A Bulks List. It is intended solely for controlled in vitro and in vivo animal model research.

Adipotide FTPP
Adipotide is a synthetic chimeric peptidomimetic studied in preclinical research models for its targeted interaction with white-adipose-tissue vasculature. Its structure combines the CKGGRAKDC homing domain with the D(KLAKLAK)₂ proapoptotic effector domain. PubChem lists Adipotide under CID 163360068, while RUO catalogues commonly reference the acetate salt under CAS 859216-15-2. For research use only. Not approved for human use.

Dermorphin
Dermorphin is a naturally occurring opioid heptapeptide derived from Phyllomedusa sauvagei frog skin secretions. Defined by its unique D-Ala² substitution, it exhibits exceptional μ-opioid receptor selectivity and potency in animal models. Dermorphin is not FDA-approved for human or veterinary use, has no recognized clinical pathway in the U.S., and remains a Class I banned substance in equine sport. This resource provides educational and regulatory information for research and professional reference only.

Thymalin
Thymalin is a heterogeneous thymic polypeptide complex originally isolated from young calf thymus tissue. Unlike single synthetic peptides, it has no single molecular formula or PubChem CID and is composed of multiple bioactive short peptide fractions, including KE dipeptide, EW dipeptide, and EDP. It is distinct from Thymulin, a defined zinc-dependent nonapeptide often confused with Thymalin in the peptide market. In the United States, Thymalin is not FDA-approved and has been specifically cited in FDA enforcement action as an unapproved new drug, making accurate, educational, and non-therapeutic positioning essential.
