Beyond the Needle
While subcutaneous injection remains the standard administration route for many research peptides, significant innovation is occurring in needle-free delivery technologies. These platforms aim to improve convenience, reduce administration complexity, and potentially enhance bioavailability for specific compound classes.
Oral Dissolvable Strips
ODS technology represents the most mature needle-free peptide delivery platform, using thin polymer films that dissolve on the sublingual mucosa for direct systemic absorption. Advantages include precise dosing, portability, and bypass of GI degradation. ROEHN's Pocket Strips line exemplifies this approach for research compound delivery.
Microneedle Patches
Microneedle arrays — patches containing hundreds of microscopic needles (100-1000 μm in length) — penetrate the stratum corneum without reaching nerve endings or blood vessels, enabling pain-free transdermal delivery. Research has explored dissolving microneedles that release peptide payloads as the needle matrix dissolves in the skin.
Nasal Delivery
The nasal mucosa offers another non-invasive absorption surface for peptide delivery. Nasal sprays have been investigated for delivering peptides including oxytocin, desmopressin, and GLP-1 analogs, with bioavailability typically in the 5-15% range.
Transdermal Systems
Iontophoresis (electrical current-assisted delivery), sonophoresis (ultrasound-assisted delivery), and nanoparticle-enhanced transdermal systems are being explored in preclinical research for peptide delivery through intact skin.
ROEHN continues to invest in delivery innovation alongside our core catalog of research peptides, including BPC-157, TB-500, and Semaglutide.
