Metabolic Signaling Research

Retatrutide — Research Guide

Retatrutide is an investigational triple-agonist peptide that binds the GLP-1, GIP, and glucagon receptors. It is one of the most cited compounds in current incretin-class metabolic-signaling research and is studied alongside earlier dual and single agonists (Tirzepatide, Semaglutide) to isolate the contribution of glucagon co-agonism.

Metabolic Signaling Research

Tirzepatide — Research Guide

Tirzepatide is a dual GIP / GLP-1 receptor agonist peptide. It is widely used in incretin-class metabolic-signaling research as the reference dual-agonist control alongside single-target agonists (Semaglutide) and triple-target agonists (Retatrutide).

Metabolic Signaling Research

Semaglutide — Research Guide

Semaglutide is a single-target GLP-1 receptor agonist peptide and the canonical reference compound for GLP-1-receptor research. As the longest-running modern GLP-1 analogue with extensive literature, it serves as the baseline against which newer dual- and triple-agonists are compared.

Tissue Signaling Research

BPC-157 — Research Guide

BPC-157 is a synthetic pentadecapeptide fragment derived from Body Protection Compound, a protein originally isolated from gastric juice. It is one of the most widely cited research peptides in tissue-signaling literature, frequently studied alongside TB-500 in cell-migration, angiogenesis, and extracellular-matrix research.

Dermatological Signaling Research

GHK-Cu — Research Guide

GHK-Cu is a copper-binding tripeptide (Gly-His-Lys complexed with Cu²⁺) that occurs naturally in human plasma. It is extensively studied in dermatological signaling, wound-model, and extracellular-matrix research, and is one of the most-cited compounds in copper-peptide gene-expression literature.

Cellular & Mitochondrial Research

MOTS-c — Research Guide

MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded by the mitochondrial 12S ribosomal RNA. It is a foundational compound in cellular and mitochondrial signaling research and is studied in metabolic-pathway and AMPK-axis literature.

Neuropeptide Research

Selank — Research Guide

Selank is a synthetic heptapeptide analogue of tuftsin developed in Russia as a neuropeptide research compound. It is studied in anxiolytic-pathway, cytokine-modulation, and neuropeptide-receptor research, and is one of the most-cited compounds in modern tuftsin-derivative literature.

Neuropeptide Research

Adamax — Research Guide

Adamax is a chemically modified Semax analogue incorporating an adamantane moiety. The adamantane modification confers enhanced metabolic stability in published characterizations relative to parent Semax, making it a useful research tool for time-extended neuropeptide assays.

GH Secretagogue Research

Tesamorelin — Research Guide

Tesamorelin is a synthetic growth-hormone-releasing-hormone (GHRH) analogue carrying a trans-3-hexenoic acid modification on the N-terminus. It is studied as the reference GHRH analogue in growth-hormone-secretagogue receptor research and is one of the most-cited modified-GHRH compounds in modern endocrinology literature.

Dermatological Signaling Research

Melanotan II — Research Guide

Melanotan II is a cyclic 7-amino-acid synthetic peptide and a non-selective melanocortin-receptor agonist. It is widely used in melanocortin-receptor signaling research and is one of the most-cited reference agonists in MC1R / MC3R / MC4R / MC5R selectivity studies.

Neuromodulator Research

DSIP — Research Guide

DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide neuromodulator originally isolated from rabbit cerebral venous blood. It is studied as a neuromodulator-class compound in receptor-binding and CNS-pathway research and is one of the most-cited nonapeptide neuromodulator references.

Cellular & Mitochondrial Research

NAD+ — Research Guide

NAD+ (Nicotinamide Adenine Dinucleotide) is a fundamental coenzyme in cellular energy metabolism. Unlike most compounds in our catalog, NAD+ is a small molecule (not a peptide). It is one of the most-cited research substrates in mitochondrial-function, sirtuin-pathway, and cellular-bioenergetics literature.

Research Blends

Wolverine Stack — Research Guide

The Wolverine Stack is a pre-mixed lyophilized formulation of BPC-157 + TB-500 (5mg of each per vial). It is commonly used in tissue-signaling research because the two compounds act through complementary mechanisms — BPC-157 via nitric-oxide and growth-factor pathways, TB-500 via actin sequestration and cell migration.

Research Blends

Klow Stack — Research Guide

The Klow Stack is a multi-peptide pre-mixed lyophilized blend totaling 80mg per vial. It spans neuropeptide and tissue-signaling research pathways and is used in cross-pathway research designs where matched-concentration access to multiple compounds simplifies experimental setup.

Research Blends

Glow Stack — Research Guide

The Glow Stack is a multi-peptide lyophilized blend centered on GHK-Cu, formulated for dermatological-signaling and dermal-fibroblast research. It is used in copper-peptide combination studies and dermal extracellular-matrix research designs.

Research Blends

Semax + Selank Blend — Research Guide

The Semax + Selank Blend is a pre-mixed lyophilized cognitive-dual-stack — 10mg of Semax and 10mg of Selank per vial. Both are heptapeptide-class neuropeptide research compounds; the pre-blended format is convenient for combination-research designs targeting both ACTH-derivative and tuftsin-analogue receptor systems.

GH Secretagogue Research

HGH 191AA — Research Guide

HGH 191AA is recombinant human growth hormone produced in a 191-amino-acid full-length sequence (somatropin). It is the canonical reference compound in growth-hormone-axis research and is studied alongside GHRH analogues (Tesamorelin) and growth-hormone-secretagogue peptides.
