In-depth research guides covering peptides, compounds, and laboratory supplies. For research use only.
Peptides and proteins are both built from amino acids, but their size difference creates major distinctions in structure, synthesis, bioavailability, and research applications. Learn where the boundary falls and why it matters for your research.
What Does the Research Say About Peptides and Tissue Healing? Tissue healing — whether tendons, joints, ligaments, or soft tissue — is one of the most extensively studied applications of peptide research. While anti-inflammatory drugs and physical therapy remain the conventional approaches to tissue repair, a growing body of preclinical and clinical evidence points to…
A deep-dive into thymus-derived peptides and immunosenescence research — thymic involution with age, Thymosin Alpha-1’s FDA orphan drug status and T-cell effects, Thymulin’s zinc-dependent modulation, and the broader landscape of immune aging.
When RFK Jr. went on Joe Rogan and named 14 peptides he wanted removed from Category 2 restrictions, the research community took notice. Here’s the full list, what Category 2 actually means, and what could change.
On February 27, 2026, HHS Secretary Robert F. Kennedy Jr. appeared on The Joe Rogan Experience (Episode #2461) and made what may prove to be the most consequential statement about peptide regulation in years.
PEGylation explained for non-specialists — what polyethylene glycol is, how attaching it to peptides extends half-life from minutes to days, real-world examples like PEG-MGF vs MGF, and the trade-offs including anti-PEG antibodies.
A deep-dive into three peptides investigated for gastrointestinal applications — BPC-157’s cytoprotective mechanisms, KPV’s NF-kB modulation in colitis models, and LL-37’s dual role in gut defense and immune regulation.
An accessible guide to antimicrobial peptide (AMP) research, covering how LL-37 kills bacteria via membrane disruption, KPV suppresses inflammation through NF-kB inhibition, and why AMPs may help address the antibiotic resistance crisis.
A deep-dive research guide to Orexin B (hypocretin-2), covering its OX2R receptor selectivity, structural differences from Orexin A, narcolepsy connection, metabolic research on obesity resistance, and role in mesolimbic reward signaling.
An accessible overview of senolytic peptide research, covering how FOXO4-DRI targets senescent cells via p53 disruption, Epithalon activates telomerase, and other peptides like GHK-Cu, SS-31, and MOTS-c address different hallmarks of aging.
