GHK-Cu & TB-500 & BPC-157 peptide blend, often referred to in research contexts as the Glow Blend, is a composite investigational formulation developed to examine coordinated regenerative signaling networks. It integrates three structurally distinct peptides studied for roles in cytoskeletal regulation, angiogenic signaling, extracellular matrix remodeling, and metal peptide coordination chemistry. BPC-157 is a 15-amino...

Ipamorelin is a synthetic pentapeptide formally classified as a Growth Hormone Secretagogue. Its amino acid sequence is Aib-His-D-2-Nal-D-Phe-Lys-NH₂, incorporating non-proteinogenic residues that may support receptor selectivity and metabolic stability. This compound was rationally developed as a ligand targeting the ghrelin receptor, also designated the Growth Hormone Secretagogue Receptor type 1a, a class A G-protein coupled...

Melanotan 1, also referred to as MT1, is a synthetic peptide structurally related to the endogenous alpha melanocyte-stimulating hormone, α-MSH. The peptide consists of 13 amino acids, matching the length of α MSH, with two targeted substitutions that differentiate it from the native sequence. These modifications include the replacement of methionine at position four with...

Sermorelin is a synthetic peptide composed of 29 amino acids and corresponds to the N-terminal fragment of endogenous growth hormone-releasing hormone. It is structurally identified as GHRH 1 to 29 amide and represents the shortest sequence reported to retain receptor-level biological activity associated with the growth hormone-releasing hormone family. The endogenous GHRH molecule consists of...

CJC-1295 DAC, also referred to as DAC: GRF or long-acting growth hormone-releasing hormone (GHRH) analog, is a synthetic 29-amino acid peptide derived from the endogenous GHRH sequence.1 It represents a tetrasubstituted analog, incorporating D-Ala, Gln, Ala, and Leu substitutions at positions 2, 8, 15, and 27, respectively. These targeted modifications are intended to support molecular...

Modified GRF 1-29, also referred to as CJC 1295 without DAC or the tetra-substituted GRF 1-29, is a synthetic analogue of growth hormone releasing hormone. It contains the first 29 amino acids of endogenous GHRH, which early studies identified as the minimal sequence capable of retaining the functional characteristics of the full 44 amino acid...

Syn-Coll, also known as Palmitoyl Tripeptide-5 (Palmitoyl-Lys-Val-Lys), is a synthetic tripeptide developed to replicate the biological activity of thrombospondin-1 (TSP-1), an extracellular matrix glycoprotein considered to be involved in cellular signaling and structural maintenance. Research suggests that the design of Syn-Coll was based on short peptide motifs within TSP-1. Specifically, the structure in TSP-1 that...

Decapeptide-12 is a synthetic oligopeptide composed of twelve amino acids (Tyr-Arg-Ser-Aar-Lysd-Tyr-Ser-Ser-Trp-Tyr). It does not appear to mimic any naturally occurring peptide but was designed by researchers with the intent to target specific enzymatic pathways. The peptide has been primarily studied for its inhibitory potential on tyrosinase, an oxidase enzyme that is considered to play a...

Syn-AKE is a synthetic tripeptide engineered to possibly replicate the bioactive function of Waglerin-1, a polypeptide component of the venom of the Malaysian Temple Viper (Tropidolaemus wagleri). Waglerin-1, a 21-amino-acid peptide, appears to exhibit neuromuscular blocking activity by interfering with signal transmission at the neuromuscular junction. Syn-AKE is considered to retain the essential pharmacophore of...
