Solid-Phase Peptide Synthesis: How SPPS Works Step by Step
Learn how solid-phase peptide synthesis works: the resin, the Fmoc cycle, coupling reagents, cleavage, common failures, and what it means for peptide purity.
Dihexa Research: What the Studies Show and What They Don’t
What Dihexa research actually shows: rodent studies, a retracted key paper, no human trials, FDA and WADA status, and how labs should vet any lot.
Peptide Research Protocols: A Practical Lab Guide for 2026
Build peptide research protocols that hold up: reconstitution, storage, QC checks, sharps safety and the FDA line on research-use-only products.
Peptide Solubility: How to Dissolve Peptides in the Lab
Why some peptides won’t dissolve and how to fix it: charge, pH, pI, co-solvents, buffers and documentation habits for U.S. research labs.
LC-MS for Peptides: How It Works and What to Check
How LC-MS confirms peptide identity and purity, how it differs from HPLC alone, and what to look for in a lot’s Certificate of Analysis.
Research Use Only Labeling: What the Label Means and Doesn’t
What a research use only label legally means in the US, what FDA says about intended use, and how labs can check that a peptide label holds up.
Melanotan 2 Research: What the Studies Show and Don’t
What published Melanotan II research shows on receptors, tanning, sexual function and safety, plus its US legal status and how labs should vet a batch.
Hormone Support Peptides: Why a Batch COA Comes First
Learn how hormone support peptides work, where evidence remains limited, what clinicians monitor, and why verified batch Certificates of Analysis matter.
Oral Peptide Bioavailability: Why Under 1% Can Still Work
Learn how FDA AUC and Cmax guidance, oral semaglutide evidence, and a candidate triage checklist help researchers interpret low peptide exposure.
Kisspeptin-10 Research: Why Purity Alone Can Fail U.S. Labs
U.S. labs can verify Kisspeptin-10 with COA and mass spectrometry, reduce degradation through careful handling, and follow research use only labeling rules.
