Thymosin Beta-4, commonly designated as TB-500 in laboratory settings, is a naturally occurring peptide comprising 43 amino acids originally isolated from thymus tissue.
Cerebrolysin is a complex mixture of low-molecular-weight peptides and free amino acids derived from the controlled enzymatic hydrolysis of porcine brain proteins.
Thymosin Alpha-1 (T-alpha-1) is an acidic polypeptide consisting of 28 amino acids originally isolated from thymus tissue fraction 5.
Prostamax (also described in the literature as a synthetic or tissue-derived peptide biomodulator preparation) is a low-molecular-weight peptide complex
Melanotan-II (MT-II) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH) belonging to the class of melanocortin receptor agonists.
