Reconstitution needle size

The original poster has used 30G 25mm needles and is considering 25G 25mm instead. One user recommends 25G 38mm needles for faster flow and reaching the bottom of small vials during transfers. They described combining six 10mg vials into one by sequential transfer starting with 1ml bac water. Another user wondered if sequential transfer might affect peptide stability or cause aggregation.

• 25G 38mm needles suggested for better flow and vial bottom access
• Sequential reconstitution across multiple vials described as efficient
• 30G 25mm previously used by the OP
• Concern raised about possible stability or aggregation issues from the method

Whether sequential transfer between vials risks peptide stability or increases aggregation

Nothing here is advice.
