In-depth research guides covering peptides, compounds, and laboratory supplies. For research use only.
What separates research-grade from pharmaceutical-grade peptides? This guide covers purity thresholds (95% vs 99%+), GMP vs non-GMP synthesis, endotoxin testing, what ‘research use only’ means legally, and how to evaluate peptide suppliers using COA data.
What Does the Research Say About Peptides and Immune Function? The immune system is one of the most complex biological systems in the human body — and it’s increasingly becoming a target for peptide-based research. While vaccines and immunotherapy drugs dominate the clinical landscape, a growing body of evidence points to specific peptides that modulate…
A deep-dive into HPG axis peptide research: how kisspeptin’s 2003 discovery revealed the GnRH pulse generator, the paradox of continuous vs pulsatile gonadorelin, KNDy neuron mechanisms, and kisspeptin’s emerging role in fertility research including IVF triggering.
What does research show about stopping peptide administration? This article examines discontinuation effects across GH secretagogues, BPC-157, melanocortin peptides, and bioregulators — covering rebound phenomena, healing persistence, receptor tolerance, and cycling concepts.
A deep comparison of three AMPK-activating compounds used in metabolic research: AICAR (direct ZMP-mediated AMPK activation), MOTS-c (mitochondrial-derived peptide with endogenous exercise signaling), and SLU-PP-332 (synthetic ERR agonist). Includes head-to-head comparison table and verified citations.
GHK-Cu research extends far beyond cosmetics. Explore the science of copper peptides in wound healing, lung remodeling, anti-fibrotic effects, gene expression modulation, and neuroprotective research — with verified citations.
What Does the Research Say About Peptides for Skin and Hair? The cosmetic peptide industry is massive — but behind the marketing, there is genuine published research on peptides that influence collagen synthesis, skin remodeling, melanogenesis, and hair follicle signaling. Some of these compounds have robust preclinical evidence. Others have moved into clinical trials. And…
A comprehensive scientific review of peptide degradation pathways including oxidation, deamidation, hydrolysis, aggregation, and racemization — with practical guidance on buffer pH, temperature, excipients, and storage strategies to preserve peptide integrity in research settings.
A comprehensive chemistry primer covering peptide bond formation, planarity, the four levels of protein structure, disulfide bridges, cyclization strategies, and how SPPS builds peptides one bond at a time.
From the discovery of the incretin effect to semaglutide and triple agonists like retatrutide, trace the science of GLP-1 receptor signaling — including cAMP/PKA pathways, central appetite regulation, and cardiovascular protection.
