What Research Peptides Are Actually Being Studied For
A grounded overview of the therapeutic areas where peptide research is concentrated, what the evidence base looks like in each, and how to read the literature without overstating it.

Growth Hormone Secretagogues: GHRH Analogues Versus Ghrelin Mimetics
Two mechanistically distinct receptor systems both raise growth hormone output. Understanding the difference is the key to designing interpretable experiments on the GH axis.
Melanocortin Peptides: Receptor Subtypes, Selectivity and the PT-141 Story
Five receptor subtypes controlling pigmentation, energy balance, inflammation and sexual function. Selectivity is the whole problem, and the reason two closely related peptides behave very differently.
Thymosin Alpha-1: Immune Modulation Research
A thymic peptide with an unusually long clinical history, approvals in some jurisdictions and not others, and a mechanism centred on dendritic cell and T-cell maturation.
Why Your Peptide Assay Disagrees: Purity, Counter-Ions and Reproducibility
Most irreproducible peptide results are not biology. They are material. A practical guide to the variables that make the same nominal compound behave differently between batches and between laboratories.
How Research Peptides Are Made: Solid-Phase Synthesis, Purification and Cost
Understanding how a peptide is built explains why some sequences cost ten times more than others at the same purity, and where the impurities in your vial come from.
