Peptide Pens

Research peptides supplied in a pre-filled peptide pen, ready to use straight from the box. Filled individually at the point of order from the same independently tested material as our powder vials — HPLC purity and mass-spectrometry identity, certified per batch.Every pen in the range is made up with 3ml of bacteriostatic water as standard, so the concentration is fixed and consistent whichever pen you order. Supplied strictly as laboratory research reagents — not for human or veterinary use.
