I 'm going to start injecting melanotan* 2 soon. I'm planning to start on a low dosage ...so do I just take what I need from the vial and leave the rest for the next day? Can oxygen/ contaminants get in the bottle and affect it or anything??
Do I have to open a new vial each time I draw up?
Hey Goldgirl, good questions. Check Peptide Calculator, your multi-dose vial will be good for many draws. Do not reuse needles, all should remain clean/sterile without contamination.
