Peptide Product Formats
Peptide Product Formats
Understanding the different formats available for research peptides. Each format has specific advantages depending on your research requirements.
Lyophilized Powder
Currently Available
The gold standard for peptide research. Freeze-dried powder offers maximum stability, longest shelf life (up to 36 months at -20°C), and precise dosing control through reconstitution.
- Shelf Life: 24-36 months (stored properly)
- Storage: -20°C long-term, 2-8°C short-term
- Reconstitution: Required (bacteriostatic water)
- Precision: Highest — full control over concentration
Pre-Mixed Pens
Coming Soon
Pre-filled injection pens with peptides already reconstituted at standardized concentrations. Eliminates reconstitution steps — ideal for labs requiring quick setup and consistent dosing.
- Shelf Life: 6-12 months (refrigerated)
- Storage: 2-8°C required
- Reconstitution: Not needed
- Precision: High — pre-calibrated doses
We are evaluating pen-format suppliers for BPC-157 and TB-500. Subscribe to our newsletter for launch updates.
Nasal Spray Format
Coming Soon
Nasal delivery format being studied for peptides with demonstrated mucosal absorption potential. Currently under evaluation for select peptides including GHK-Cu and BPC-157.
- Shelf Life: 3-6 months (refrigerated)
- Storage: 2-8°C required
- Reconstitution: Pre-prepared
- Precision: Moderate — metered spray doses
Nasal spray formats are in research evaluation phase. We are assessing supplier GMP compliance and stability data.

Our Recommendation
For most research applications, lyophilized powder remains the optimal format. It offers the best stability, lowest cost per milligram, and maximum flexibility in dosing. Our lyophilized peptides ship with full Certificates of Analysis and are stored in our temperature-controlled facility at 2-8°C until dispatch.
