The Science

What are peptides, exactly?

Peptides are the body’s own messengers. Understanding what they are — and how they actually work — is the difference between guessing and researching.

🧬

Short chains of amino acids

Peptides are short strings of amino acids — the same building blocks as proteins, just smaller (usually 2–50). Your body already makes thousands of them to run everyday functions.

🔑

They work like a key in a lock

Each peptide fits one specific receptor on a cell and delivers a single, precise instruction — release growth hormone, calm inflammation, repair tissue, or regulate appetite.

🎯

Precisely targeted

Because one peptide usually triggers one signal, they're studied for precision — a targeted nudge to a single pathway instead of a broad, blunt, whole-body effect.

🔬

Purity is everything

In research the result is only as clean as the compound. Every batch here is HPLC + mass-spec verified to ≥ 99% purity.

Everything here is for laboratory research use only — not for human or animal consumption. Figures are compiled from published research literature.

The delivery system · Anatomy of the particle

Three layers, one job.

Every drop carries millions of nano-encapsulated particles. Each is built to stay sealed where it must, and open where it should.

Cross-section of the nano-encapsulated particle

60–300 NANOMETRES

1

Functional nano-micellar core

The bioactive payload sits in a micellar structure able to bind both lipid-soluble and water-soluble actives together in one stable centre.

2

Cross-linked hydrocolloid matrix

Polysaccharide chains bind electrostatically into a three-dimensional gel network that traps water, reinforces structural integrity, and forms a steric barrier shielding the core from the harsh gastric environment.

3

Hygroscopic interface layer

An outer coating that holds moisture, keeps the particle flexible, promotes mucosal adhesion, and lets it disperse evenly the instant it meets water.

The transport pathway

Six barriers stand between a peptide and a cell.

From the moment it's swallowed, a peptide runs a gauntlet. Here's every obstacle — and how the encapsulation is engineered to get past each one.

Stage

The barrier

How we get through

Ingestion

Barrier 1 · Product stability

Peptides must be stabilised at a bioavailable size and protected from degradation before they're even swallowed.

Protected from the start

A nano-sized micellar hydrocolloid shell forms around the peptide — one that disperses instantly and uniformly through water.

Stomach

Barrier 2 · Compound stability

Up to two hours in acid at pH 1–3, plus pepsin and digestive enzymes, plus mechanical churning. Most peptides end here.

Passes straight through

The cross-linked matrix forms a steric barrier against acid and enzymes, and moves through without triggering the pyloric valve or a digestive response.

Small intestine

Barrier 3 · Absorption

Particles must shrink enough to be absorbed — without bile salts and proteolytic enzymes denaturing the peptide on the way.

Disassembles on cue

The shell comes apart cleanly in the intestine, and the particle size allows rapid uptake at the microvilli without requiring enzymes.

Portal vein & liver

Barrier 4 · First-pass metabolism

Whatever survives is routed to the liver, where enzymes catabolise or modify it before it ever reaches circulation.

Takes the other road

The micellar hydrocolloid is absorbed via the lacteal and funnelled through the lymphatic system into blood — bypassing the first-pass gauntlet.

Bloodstream

Barrier 5 · Systemic distribution

Peptides must be distributed through the body and taken into tissue before the kidneys clear them out.

Releases its payload

The carrier dissociates in the blood, separating the oil fraction from the peptide fraction and freeing the active peptide to circulate.

Interstitial fluid

Barrier 6 · Lymphatic clearance

The peptide has to be used by the cells before it's drained back into the lymph and recirculated away.

Delivered to the cell

Circulating peptides are absorbed into tissue and interstitial fluid for rapid delivery — where they can finally interact at the cellular level.
