Peptides 101
What is a peptide? Explained visually, for beginners
No jargon and no marketing. Five interactive explanations that cover what peptides are, how they act on cells, how they differ from one another, and why purity and storage decide whether a dose does anything at all.
Visual 1
From amino acids to peptides (the building-block explanation)
Stage 1 — separate blocks. Each circle is one amino acid. On their own they do nothing in particular. Think LEGO blocks in a box.
Animation showing individual coloured amino acid blocks linking together to form a peptide chain, then comparing a short peptide chain with a much longer protein chain.

How peptides work: the key-and-lock explanation
Scene 1 — the key. Your peptide. Its amino acid order gives it one specific shape, and that shape is the whole story.
Animation of a peptide drawn as a key travelling to a cell covered in receptor locks, sliding into a matching lock, and the cell then lighting up with different effects for GLP-1, BPC-157, TB-500 and NAD+.

Different peptides, different jobs
GLP-1
Metabolic / weight-management peptide
Job
Signals the gut and brain to slow eating and increase fullness
Reported result
- ↓ Appetite
- ↓ Body weight
- ↑ Fullness
BPC-157
Repair-signalling peptide (research only)
Job
Studied for angiogenesis and tissue repair signalling
Reported result
- ↑ Repair signalling (animal data)
- ↓ Reported pain
- Human data limited
TB-500
Recovery peptide (research only)
Job
Studied for cell migration and actin regulation
Reported result
- ↑ Reported recovery
- ↑ Range of motion claims
- No human trials
NAD+
Coenzyme, not strictly a peptide
Job
Feeds the cellular energy pathways that decline with age
Reported result
- ↑ Cellular energy substrate
- Mixed human outcomes

Why peptide purity matters: 95% vs 50%
95% pure
Verified, correctly stored vial
95 units of active peptide per dose
Full expected effect ✓✓✓✓✓
50% pure
Underdosed, degraded or counterfeit vial
50 units of active peptide per dose
Roughly half the effect ✓✓
You are not getting what you paid for — and at the label dose you would never know. That is what verification is for.
Verify your peptides now →Side-by-side diagram of two 100-square dose grids: at 95 percent purity 95 squares are active peptide, at 50 percent purity only 50 are, meaning half the intended dose.

How storage affects your peptide
Refrigerated (2–8 °C)

Storage matters more than most people think. A vial that tested clean on arrival can still be under-strength by the time it reaches the last dose.
Interactive timeline comparing potency of a refrigerated peptide vial, which declines gradually from 100 percent to about 70 percent over a year, with a vial left at room temperature, which drops steeply within the first weeks.
