Orders are processed within 1–3 business days (Monday–Friday, excluding federal holidays). Orders placed after 2:00 PM PT may not be processed until the following business day.

Packaging & Storage
- Vials
- Sealed, light-protected
- Store on arrival
- Room temperature
All lyophilized peptides are shipped in sealed, light-protected vials inside protective packaging. Lyophilized (freeze-dried) material is stable at room temperature, so orders do not require refrigerated shipping. Upon receipt, store products as specified on the product label and Certificate of Analysis - room temperature, sealed and dry, for the lyophilized powder, or 4°C for short-term use after reconstitution.
