Deep-dives on peptides, stacks, and the science behind them.
Why Peptides Degrade and How to Prevent It
Peptides are fragile molecules. Heat, light, oxygen, the wrong water, even freeze-thaw cycles can wreck them. Here's what actually causes degradation and how to stop it.
Peptide Pharmacokinetics Basics
Absorption, distribution, metabolism, elimination — the journey a peptide takes from your syringe to the receptor, and why it shapes almost every practical decision.
How GLP-1 Works
Semaglutide, tirzepatide, retatrutide — they all mimic GLP-1, a gut hormone. Here's what GLP-1 actually does, why weight loss follows, and how the newer compounds differ.
The GH Axis, Explained
Sermorelin, CJC-1295, ipamorelin, tesamorelin, MK-677 — they all work on the same system but hit different nodes. Here's a clean map of the GH axis and where each peptide acts.
Half-Life and Why It Matters
Half-life is the single most important number for figuring out how often to dose a peptide. Here's what it actually means and how it varies across the classes people use.
How Peptides Signal in the Body
Peptides don't enter cells like small drugs do. They bind receptors on the outside and trigger a cascade on the inside. Here's how that actually works.
