Tirzepatide is a dual GIP/GLP-1 receptor agonist used for weight management and glycemic control in type 2 diabetes. It promotes fat loss by suppressing appetite and delaying gastric emptying.
Retatrutide (LY3437943) is a first-in-class triple agonist peptide that simultaneously activates the GLP-1, GIP, and glucagon receptors. Compared with dual agonists, this innovative triple mechanism delivers more pronounced weight loss, higher energy expenditure, and greater hepatic fat oxidation. In a Phase II clinical trial, retatrutide achieved an average weight loss of 24.2% at 48 weeks; the Phase III TRIUMPH-4 trial showed an average weight loss of approximately 28–29% at 68 weeks, together with significant improvement in knee pain. In addition, retatrutide shows notable advantages in reducing liver fat, lowering glycated hemoglobin (HbA1c) levels, and improving cardiovascular risk markers, with side effects consisting mainly of gastrointestinal reactions similar to those of incretin therapies. Retatrutide represents a new generation of highly effective metabolic therapeutics.
BPC-157 is a synthetic 15-amino acid pentadecapeptide derived from a protective protein found in human gastric juice. It has shown remarkable regenerative and cytoprotective effects in over 100 preclinical studies through multiple mechanisms, including upregulation of VEGFR2, enhanced nitric oxide synthesis, and modulation of the FAK-paxillin pathway. Research demonstrates its ability to accelerate tendon, ligament, muscle, and bone healing, promote angiogenesis, support peripheral nerve regeneration, protect and repair the gastrointestinal tract against NSAID, alcohol, and toxin-induced damage, and aid wound healing. It is generally well-tolerated with a strong safety profile in preclinical models, though caution is advised in subjects with active malignancies due to its pro-angiogenic properties. BPC-157 is widely researched for sports injury recovery, gut health restoration, post-surgical healing, and synergistic use with TB-500.
GHK-Cu (Copper Peptide) is a small molecule copper-binding peptide widely used in skincare and medical aesthetics, primarily to promote skin repair, anti-aging, and wound healing.
A useful product page should let you verify identity, specification, intended laboratory use and available batch documentation before you decide.
Open the product's COA section and match the document, product and batch identifier. Review the reported analytical method and results.
Read the storage statement on the product page and any batch-specific instructions, so the stated conditions can be maintained.
Check the selected concentration, pack quantity and stock status so the requested material matches your research plan.
Researchers and laboratory teams across three continents.
"Their COA practices set the bar for the industry. We've switched all our research procurement to Peptiva Bio."
"I've tested 12 vendors with HPLC. Peptiva Bio was the only one that matched their stated purity, every time."
"The lyophilized material arrives stable and well-documented. It has been a constant in our lab for two years."
