Pre-filled pens, ready to use.
Order peptides pre-loaded into a research delivery pen instead of a lyophilised vial. We handle reconstitution and dosing in our lab — bacteriostatic water included — and you receive a ready-to-use pen, calibrated to the vial dose you selected. Available per product from the product page.

Every batch, third-party tested.
Astrel Bio batches are released only after independent HPLC and mass-spectrometry verification by Janoshik Analytical*. Each order ships with a batch-matched certificate of analysis, and every lot number is verifiable from the product page.
* Our primary laboratory; where lead times or availability require it, we occasionally use another reputable independent lab.
