The Science

The evidence behind buccal delivery.

Peptides are extraordinary molecules — and extraordinarily hard to deliver. The whole case for NeoPep rests on one idea: the route matters as much as the molecule.

The problem

Why most peptides never reach the bloodstream.

The gut

Swallowed & destroyed

Taken orally, peptides meet a wall of stomach acid and digestive enzymes that break them apart before absorption. What little survives faces the liver’s first‑pass metabolism — so oral bioavailability is typically very poor — often close to negligible for peptides.

The needle

Effective, but dreaded

Injection solves the absorption problem but creates new ones: pain, disposal, cold storage and poor adherence. People skip doses they fear — and a dose not taken has zero bioavailability.

The route

The cheek is a shortcut to the bloodstream.

The buccal mucosa — the lining of the inner cheek — is thin, permeable and densely supplied with blood vessels that drain directly into systemic circulation. Delivering a peptide here bypasses both the digestive tract and the liver’s first‑pass metabolism, so far more of the active molecule arrives intact. That single detour is what makes the difference below.

Tablets & capsulesVery poor or nil
Oral dissolving stripsVery poor — less than 10%
TD‑IntelGel™ buccal patchVery high — 65–90% (human clinically tested)
Injections / IVVery high — 90%, but needle-based

* Comparative delivery performance for peptides; performance may vary by peptide, formulation and study conditions.

Where peptides help

One route, many mechanisms.

Repair & recoveryPeptides studied for tissue, tendon and muscle repair after strain or injury.
Metabolic & energyMolecules tied to cellular energy production and mitochondrial function.
Cognition & sleepSignalling peptides associated with focus, calm and sleep architecture.
ImmunityThymic peptides researched for their role in modulating immune response.
Skin & beautyCopper peptides linked to skin renewal, firmness and repair.
Vitality & longevityAntioxidant and NAD‑pathway compounds explored for healthy aging.

A note on claims. NeoPep products are intended as supplements, not medicines, and the information here is educational rather than medical advice. Individual results vary, and research into many peptides is ongoing. If you are pregnant, nursing, taking medication or managing a health condition, please consult a qualified healthcare professional before use.
