Vasoactive intestinal peptide (VIP) is described as a peptide composed of 28 amino acids, originally discovered in 1970 and initially recognized for its potential to promote the widening of blood vessels (vasodilation). (1) VIP is classified as part of the secretin/glucagon hormone superfamily, a group of related hormones involved in regulating various physiological functions. VIP […]

PTD-DBM Peptide: Research in Hair Growth and Wound Repair
The PTD-DBM peptide is a fusion protein that research indicates is a potentially synergistic combination of the transduction properties of the Protein Transduction Domain (PTD) with the functional domain of the Dishevelled Binding Motif (DBM). Dishevelled (DVL) is a key mediator of the Wnt signaling pathway, which is believed to play a role in regulating […]
Tripeptide-1 (GHK Basic) Actions on Skin Cells and Underlying Connective Tissues
Tripeptide-1 is hypothesized to be a short-chain peptide composed of the amino acids glycine, histidine, and lysine, arranged in the sequence GHK. Scientists pioneering research on Tripeptide-1, such as Pickart et al., suggest that this peptide motif appears to replicate an endogenous fragment that is reportedly produced by several types of cells, including fibroblasts, lymphocytes, […]
The Neuroprotective and Gastroprotective Potential of Semax
Semax is a synthetic heptapeptide (Met–Glu–His–Phe–Pro–Gly–Pro) originally derived from fragments of adrenocorticotropic hormone (ACTH) but lacking hormonal activity. It consists of a 4-amino acid fragment (Met-Glu-His-Phe), which is a common part in the sequence of all PT-141 peptide structure hormones, such as ACTH, and a Pro-Gly-Pro fragment as a stabilizer, which is attached at the […]
Matrixyl Peptide: Research in Anti-aging and Tissue Repair
Known by various names, including palmitoyl pentapeptide-4 and palmitoyl pentapeptide-3, Matrixyl appears to exhibit a unique structure characterized by its conjugation with palmitoyl. This structural modification is speculated to enhance its delivery across the skin and fortify its stability against enzymatic degradation by skin proteases, potentially yielding in more invigorated and healthy skin.(1) At the […]
IGF-1 LR3 Peptide and Muscle Development
IGF-1 is a naturally produced polypeptide amino acid. Endogenous Ipamorelin amino acid sequence is converted into IGF-1 to eliminate excess glucose, creating the chemical intrinsically. The synthetically developed version of IGF-1, (IGF-1 LR3) was intended by its producers to imitate this same process within the cell body. IGF-1 LR3 peptide is an extended analogue of […]
