What are Peptides?

A peptide is simply a short chain of amino acids. Because peptides are smaller than proteins, they can move through the body more easily and act as signaling molecules. They dock onto your cells like a key into a lock and turn on specific functions: "Burn fat," "Heal this tendon," or "Wake up the brain."

The Three Main Categories

A. Signaling Peptides: These tell the body to release hormones

B. Repair & Systemic Peptides: These focus on fixing damage.

Cosmetic & Lifestyle Peptides: made simply for stuff like getting tanned etc.

How the Body Actually Uses Peptides

Your body is a peptide-making factory. When you eat raw or rare meat, your body breaks down those complex animal proteins into bioactive peptides.

Best peptide to use (not ranked in order)

1. BPC-157

What it does: It accelerates angiogenesis (the formation of new blood vessels). By increasing blood flow to damaged areas, it speeds up the healing of tendons, ligaments, and muscle tears. It also works on the "gut-brain axis" to repair the stomach lining and reduce inflammation in the GI tract.
For the sub 50 IQ human: The "Super Glue." It fixes broken LEGO pieces (your boo-boos and tummy) really fast.

2. GHK-Cu

What it does: It is a DNA-repair peptide. It resets genes to a younger, healthier state. In practice, it increases collagen and elastin production in the skin, promotes hair growth, and acts as a potent antioxidant/anti-inflammatory agent.

For the sub 50 IQ human: The "Eraser." It rubs out the scratches and marks on the skin so they look brand new and shiny again.

3. Melanotan II

What it does: It mimics alpha-melanocyte-stimulating hormone. It forces the body to produce melanin, resulting in a dark tan without significant UV exposure. It also has a secondary effect on the hypothalamus that increases libido and suppresses appetite.
For the sub 50 IQ human: The "Crayon." It colors your skin brown like you’ve been playing in the sun all day.

4. LL-37

What it does: This is an antimicrobial peptide. It works as a natural antibiotic and antiviral. It kills bacteria, fungi, and viruses by disrupting their cell membranes. It’s often used to clear stubborn gut infections or SIBO.
For the sub 50 IQ human: The "Knight." It fights away the "icky bugs" and "bad germies" that try to make you sick.

2. TB-500

What it does: It promotes cell migration and differentiation. It acts like a scout that tells repair cells where to go. It is primarily used for systemic injury recovery, increasing flexibility, and reducing acute inflammation in joints.
For the sub 50 IQ human: The "Flash." It helps the little repair workers run faster to the broken parts of the castle.

Summary

They are NOT Steroids: They don't replace your hormones; they usually signal your body to produce its own.
Avoid the Junk: Stay away from "Collagen Peptides" in plastic tubs. They are industrial waste.
Bioavailability Matters: Injectable synthetics bypass the gut, but nutrient-dense animal foods provide the building blocks to ensure those signals actually achieve results.
