Product Information

Detailed information on what each product is and its primary research applications.

GLP-1

Retatrutide

+

What it is: Retatrutide is a synthetic peptide analogue and triple agonist that targets the GLP-1, GIP, and glucagon receptors simultaneously. It represents the next generation of metabolic peptide research, combining three mechanisms of action in a single molecule.

Research Applications: Metabolic optimization, weight management, glycemic control, and energy expenditure modulation. Its triple-receptor action distinguishes it from dual agonists like tirzepatide, offering a broader metabolic profile for research into obesity and metabolic syndrome pathways.

Mechanism: GLP-1 receptor activation slows gastric emptying and promotes satiety signaling. GIP receptor activation complements insulin sensitivity. Glucagon receptor activation increases energy expenditure through thermogenesis and lipid metabolism.

GLP-1

Tirzepatide

+

What it is: Tirzepatide is a synthetic dual agonist peptide targeting both the GLP-1 and GIP receptors. It is one of the most advanced metabolic research peptides available, representing a significant step beyond single-receptor GLP-1 agonists.

Research Applications: Metabolic research, appetite regulation studies, insulin sensitivity investigation, and energy balance modulation. The dual-receptor mechanism provides a more comprehensive approach than single-receptor peptides for metabolic research protocols.

Mechanism: GLP-1 agonism reduces appetite and slows gastric motility. GIP agonism enhances insulin secretion and improves adipose tissue metabolism. The synergistic effect of both receptors creates a broader metabolic response than either alone.

Healing

BPC-157

+

What it is: BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. It is one of the most extensively studied peptides for tissue repair and regeneration.

Research Applications: Tendon, ligament, and muscle tissue repair; gastrointestinal integrity and ulcer healing; angiogenesis (new blood vessel formation); systemic inflammation modulation; and post-surgical recovery acceleration. Notable for its stability in the gastrointestinal tract, allowing both oral and injectable administration routes.

Mechanism: Upregulates growth hormone receptors, promotes fibroblast and endothelial cell migration, modulates nitric oxide synthesis, and enhances angiogenic factor expression (VEGF, FGF). It also protects gastric mucosa and reduces inflammatory cytokine activity.

Healing

TB-500 (Thymosin Beta-4)

+

What it is: TB-500 is the synthetic version of Thymosin Beta-4, a naturally occurring actin-sequestering peptide found in virtually all human cells. It plays a fundamental role in cytoskeletal organization, cell migration, and tissue regeneration processes.

Research Applications: Soft tissue recovery, wound healing acceleration, reduction of inflammation in injured tissues, cardiac muscle repair research, and corneal healing studies. It is particularly notable for its role in promoting cell migration to injury sites — directing stem cells and endothelial cells where they are needed most.

Mechanism: Binds to actin monomers to regulate cytoskeletal dynamics, promotes endothelial cell migration and angiogenesis, reduces inflammation through NF-κB pathway modulation, and upregulates matrix metalloproteinases involved in tissue remodeling.

Regeneration

GHK-Cu (Copper Peptide)

+

What it is: GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding tripeptide first isolated from human plasma. It is one of the most well-documented regenerative peptides, with decades of published research supporting its role in tissue remodeling and repair.

Research Applications: Collagen synthesis stimulation, wound healing and skin regeneration, anti-inflammatory response modulation, tissue remodeling, and angiogenesis research. GHK-Cu is known for its ability to coordinate copper ions — an essential cofactor for enzymatic processes involved in collagen crosslinking and antioxidant defense.

Mechanism: Chelates copper ions essential for lysyl oxidase (collagen crosslinking) and superoxide dismutase (antioxidant defense). Modulates gene expression for >4,000 human genes including TGF-beta, collagen, and matrix metalloproteinases. Reduces pro-inflammatory cytokine production.
