Peptides 101

The plain-English foundation: what a peptide actually is, the lock-and-key mechanism, and why peptides work — explained through GLP-1, retatrutide, BPC-157 and TB-500.

A balanced, honest look at peptide safety: why the signaling-molecule mechanism makes them safer than feared, which peptides have strong track records, where the real risks live, and the prescription-drug double standard.

The single cleanest way to understand peptides: steroids FLOOD your body with the finished hormone and shut your own production off, while peptides SIGNAL your body to make more of its own — explained through growth-hormone peptides and testosterone.

Do Ozempic, Mounjaro, and Retatrutide eat your heart, esophagus, or vital organs? The honest, study-backed answer about which muscles actually disappear on the GLP-1 receptor agonist class — and the four-part playbook for keeping the muscle you want.

Reconstitution is just turning freeze-dried powder into an injectable liquid by adding bacteriostatic water. Here's the whole process — add slowly, swirl don't shake, refrigerate — plus the one piece of math that sets your dosing.

The one-minute answer is bacteriostatic water — here's what it is, why the tiny bit of benzyl alcohol matters for a vial you'll use over weeks, and the rare cases where plain sterile water is the right call.

A calm, step-by-step walkthrough of the subcutaneous peptide injection — the supplies, the technique, where on your body to do it, and how to rotate sites so it works every time.
