Usually, I would prefer one or the other, but you dont have a lot of the Oil based winny. Normally, I would suggest taking 1cc ED for 4 to 6 wks and saving the oral winny for another time. You could start with 40mg of the oral ED for 2-3 wks (splitting the dose into 2x day) and then move to the inject, taking 1cc ED for the next 3 wks. Or you could combine them. You could inject 1/2cc ED, in the morning and then take 20-30mg orally, in the evening, for a total of 6 or so wks.
Really, either would be an option, just be aware that winstrol is hard on your cholesterol profile as well as on your liver, so the longer you are on it, the more stress you put on your body.
ALSO, YOU WANT TO RUN TEST WITH WINSTROL. Make sure that you include some form of test as the base if this cycle, even if it's only at 250mg. And dont forget to do a good PCT after the cycle is over.
