Explains how each peptide works, and where the explanation stops being measured and starts being theory.
Craig Palmer writes This Peptide's pharmacology pages for the peptides beyond the GLP-1s. They cover sermorelin, NAD+, glutathione, GHK-Cu, PT-141 and the research-only peptides readers keep asking about. Each page follows a compound from the receptor it acts on to the reason it is dosed the way it is, and marks clearly where a mechanism is still a hypothesis. He writes about what a molecule does, not whether any one reader should take it. No clinical credentials are claimed here.
What they cover
- Growth-hormone-releasing peptides
- NAD+ and cellular energy metabolism
- Melanocortin receptors
- Peptide half-life and dosing schedules
- Compounding and routes of administration
