Important handling note: Tesamorelin can be more sensitive during dilution than many other peptides and may gel if the dilution solution's pH is not suitable. For best results, use a new, unopened vial of Pfizer pharmaceutical-grade dilution solution, and allow the peptide vial to reach ambient room temperature before adding dilution solution.
