Research FAQ
Common questions about peptide sciences
What are peptides and how do they work in the body? +
Peptides are short chains of amino acids (typically 2-50) that act as biological signaling molecules. They bind to specific cell receptors, triggering precise physiological responses — from hormone release to tissue repair. Unlike small-molecule drugs, peptides offer high target specificity with minimal off-target effects, making them one of the fastest-growing therapeutic modalities in modern medicine.
What is retatrutide and how does it differ from other weight loss peptides? +
Retatrutide is a triple-hormone receptor agonist targeting GLP-1, GIP, and glucagon receptors simultaneously. In Phase 2 clinical trials (NCT04881760), it demonstrated up to 24.2% weight loss at 48 weeks — outperforming dual agonists like tirzepatide. Its unique glucagon receptor activation promotes fat oxidation and energy expenditure, offering a mechanistically superior approach to peptides for weight loss.
Are collagen peptides scientifically proven to work? +
Yes. Multiple randomized controlled trials (RCTs) have demonstrated that hydrolyzed collagen peptides improve skin elasticity, dermal collagen density, and joint function. A 2021 meta-analysis of 19 RCTs (PubMed: 33867600) confirmed statistically significant improvements in skin hydration and elasticity after 90 days of daily supplementation at 2.5-10g doses.
What is BPC 157 peptide and what does the research show? +
BPC 157 (Body Protection Compound) is a 15-amino acid peptide derived from human gastric juice. Preclinical studies show it accelerates healing of tendons, ligaments, and gastric mucosa by promoting angiogenesis and fibroblast migration. While human clinical trials are limited, animal model data is robust — with demonstrated efficacy in rat tendon-to-bone healing models.
How do I use a peptide calculator for research dosing? +
A peptide calculator determines reconstitution volume and dose per unit. For example, reconstituting a 5mg peptide vial with 2mL bacteriostatic water yields a concentration of 2.5mg/mL. At this concentration, 10 units (0.1mL) on an insulin syringe delivers 0.25mg. Always verify calculations and consult published dosing protocols from peer-reviewed literature.
What are vital proteins collagen peptides and how do they compare? +
Vital Proteins collagen peptides are a commercially available hydrolyzed bovine collagen supplement. Independent lab analysis shows typical amino acid profiles of 30% glycine, 22% proline, and 12% hydroxyproline. While effective for general wellness, research-grade collagen peptides offer higher purity (>99%), verified molecular weight distribution, and full traceability for clinical research applications.
