Sublingual Peptide Strips (Needle-Free)

Sublingual strips dissolve under the tongue against a highly vascularised mucosal bed, removing the need for reconstitution or a syringe. PX1 strips use a bio-adhesive polymer matrix with precise per-strip loading.

Mucosal absorption kinetics

The sublingual mucosa is thin, permeable and drained directly into systemic circulation, bypassing first-pass hepatic metabolism that degrades orally swallowed peptides.

  • Direct systemic entry via the sublingual venous plexus
  • Avoids gastric proteolysis and first-pass hepatic degradation
  • Rapid dissolution — typically under 60 seconds

Polymer matrix and stability

A bio-adhesive film matrix holds the peptide in an amorphous dispersion, keeping it dry and stable at room temperature until the strip contacts saliva. No refrigeration or BAC water required.

Frequently asked questions

Do sublingual peptide strips need bacteriostatic water?

No. Strips are ready to use and require no reconstitution, syringe or refrigeration.

How long does a strip take to dissolve?

Most PX1 strips fully dissolve under the tongue in under a minute.
