Peptide delivery

Our injectable technology

We choose injectable technology for clear scientific and practical reasons: precise dosing, reliable delivery and consistent protocols.

The format

Designed for precision and practicality

Practical administration

Our advanced injectable peptide technology is designed for precise administration. Labbieux peptide pens are easy to prepare and feature very fine micro needles with a precise dosing mechanism.

  • Fine micro-needles support comfortable subcutaneous delivery.
  • Protocols can be self-administered after proper instruction.
  • Bypassing the GI tract reduces digestive irritation and variability.
  • Compounds enter circulation and reach target tissues systemically.

Protocol-level control

Injectable delivery supports exact dosing and adaptive protocol design. Protocols can be measured, repeated, and adjusted, allowing partners to build clearer frameworks around each formulation.

  • Combination protocols can stack peptides for synergistic effects.
  • Adaptive cycling helps maintain receptor sensitivity over time.
  • Timed administration can align dosing with circadian biology.
  • Click-release pens deliver precise, consistent units per dose.
Bioavailability

Oral vs injectable absorption

Oral peptides

<2%

Lost to digestive enzymes and metabolism.

Injectable peptides

99%

Delivered directly into systemic circulation.

Why oral peptides don’t survive

1

Stomach acid

Stomach acid starts breaking peptides down within minutes.

2

Pancreatic enzymes

Digestive enzymes break peptides into smaller pieces.

3

Brush-border enzymes

Enzymes in the intestinal wall break the remaining peptides down further.

4

Hepatic first-pass

The liver processes what remains before it can circulate through the body.
