GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide-copper chelate with documented effects on gene expression, extracellular matrix biology, and inflammatory signalling. This guide covers its molecular profile, proposed mechanisms, and the current state of preclinical research.
A research-focused overview of Thymosin Alpha-1 (Tα1), a 28-amino acid immunomodulatory peptide. Covers molecular structure, TLR signalling mechanisms, T-cell biology, research applications, and the key distinction from Thymosin Beta-4 (TB-500).
CJC-1295 is a synthetic GHRH analogue available in two research variants — with and without DAC (Drug Affinity Complex). This guide covers the mechanistic basis of GHRHR agonism, the pharmacokinetic distinction between DAC and No DAC forms, key research applications, and the synergistic CJC-1295 and Ipamorelin dual-pathway stack.
What Is Glutathione? Glutathione (GSH) is a tripeptide composed of gamma-glutamic acid, cysteine, and glycine (γ-Glu-Cys-Gly). It is the most abundant low-molecular-weight thiol in mammalian cells, with intracellular concentrations typically in the millimolar range (1–10 mM). As the cell’s primary…
What Is CJC-1295 No DAC? CJC-1295 No DAC — also referred to as MOD GRF 1-29 or Modified GRF(1-29) — is a 29-amino acid synthetic analogue of growth hormone-releasing hormone (GHRH). The “No DAC” designation distinguishes it from CJC-1295 with…
What Is MOTS-c? MOTS-c (Mitochondrial ORF of the 12S rRNA Type-c) is a 16-amino acid mitochondria-derived peptide (MDP) encoded not by the nuclear genome but by the mitochondrial genome itself — specifically within the 12S ribosomal RNA gene. First identified…
What Is Melanotan 2? Melanotan 2 (MT-II) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte stimulating hormone (α-MSH). Developed at the University of Arizona in the 1980s as part of a programme investigating photoprotection strategies, MT-II is a non-selective melanocortin…
What Is IGF-1 LR3? IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arg3) is a synthetic 83-amino acid analogue of native IGF-1 engineered for enhanced research utility. Two modifications distinguish it from endogenous IGF-1: an N-terminal 13-amino acid extension and an arginine…
What Is NAD+? Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in all living cells. It plays a central role in cellular energy metabolism, DNA repair, and gene expression regulation, and has become one of the most studied molecules in…
What Is Ipamorelin? Ipamorelin is a synthetic pentapeptide growth hormone secretagogue (GHS) with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂. First characterised in the late 1990s by researchers at Novo Nordisk, it belongs to the growth hormone-releasing peptide (GHRP) class but is distinguished by…
