It will be good for at least a month. After the loading phase I drop down to 1 to 2 mg a week. I have used it after 6 weeks with no problem and still had excellent results.
I personally can't continue injecting everyday or even eod or I get way too dark.
I mix it and freeze it, same with HCG and I have never had a problem, even after 2 months in the freezer the crap still hits me with sides the same as the day I mixed it, though I do have a nice tan.
Do you let it thaw out naturally or place it in a glass of hot water when you need another dose? Does going from solid state to liquid state at a much higher temp. affect the peptide negatively?
