A comprehensive comparison of the four primary peptide administration routes in research — subcutaneous injection, intranasal delivery, oral administration, and transdermal application — with bioavailability data, pharmacokinetic considerations, and guidance for route selection.
A practical safety guide for peptide researchers covering PPE requirements, lyophilized powder handling, reconstitution protocols, sharps disposal, cold chain storage management, documentation best practices, and spill response procedures.
A deep-dive comparison of four non-GLP-1 metabolic peptides: AOD-9604 (growth hormone lipolytic fragment), MOTS-c (mitochondrial AMPK activator), 5-Amino-1MQ (NNMT inhibitor), and Adipotide (vascular-targeted fat destruction). Mechanisms, research data, and head-to-head comparison.
An accessible guide to solid-phase peptide synthesis (SPPS), covering Merrifield’s Nobel Prize-winning method, Fmoc vs Boc chemistry, resin types, coupling reagents, purification by HPLC, and why synthesis length determines peptide quality.
What Are Peptides and SARMs — And How Do They Differ? If you’re involved in research chemical markets, you’ve encountered both peptides and SARMs (Selective Androgen Receptor Modulators). They’re often sold by the same suppliers, discussed in the same forums, and sometimes confused for each other. But peptides and SARMs are fundamentally different classes of…
A deep-dive into neuroprotective peptide research covering Cerebrolysin’s neurotrophic factor mimicry, Selank’s GABAergic modulation, Semax’s BDNF upregulation, Cortagen’s bioregulation, PE-22-28’s TREK-1 blocking, and P21’s CNTF-derived neurogenesis.
An accessible guide to the science behind multi-peptide research protocols. Learn the difference between synergy and additive effects, why receptor saturation favors combinations, and what the evidence says about popular pairings like CJC-1295/Ipamorelin and BPC-157/TB-500.
A deep-dive comparison of four wound healing peptides — BPC-157, TB-500, GHK-Cu, and LL-37 — examining their distinct mechanisms in angiogenesis, cell migration, collagen remodeling, and antimicrobial defense across the four phases of tissue repair.
What Does the Research Say About Growth Hormone Secretagogue Peptides? Growth hormone (GH) research has evolved dramatically since the first recombinant human growth hormone was approved in 1985. Rather than administering exogenous growth hormone directly, researchers are increasingly investigating peptides that stimulate the body’s own GH production through two complementary pathways: growth hormone-releasing hormone (GHRH)…
The End of an Era: Peptide Sciences Closes Its Doors On March 6, 2026, at approximately 2:00 PM Eastern, one of the longest-running names in the grey-market research peptide industry went dark. Peptide Sciences — a U.S.
