What you receive
A sealed vial of lyophilized DSIP at the size you select.
A Certificate of Analysis for that batch — purity by HPLC and identity by mass spectrometry, from an independent laboratory.
Tracked, insured shipping from Texas, dispatched within a day of payment.
Handling & storage
As supplied (lyophilized): stable at −20°C, protected from light and moisture. Short periods at room temperature during transit are normal for lyophilized material.
Once in solution: refrigerate at 2–8°C and protect from light. Solutions are far less stable than the dry powder.
Avoid repeated freeze–thaw cycles — aliquot instead if the material will be used across multiple sessions.
Reconstitution solvent depends on the compound; bacteriostatic water suits most, and IGF-class peptides need a low-pH solvent such as 0.6% acetic acid. Both are stocked under Lab Supplies.
Handling information describes the material as laboratory stock. It is not guidance for use in humans or animals.
