you don't want to dose by volume, you want to dose by concentration. Your friend may have said to use one cc/1ml,
but 1ml can range anywhere from 100 to 300mg. Typically though with Test E it seems to be 250 for the standard, and most people
consider 400-500mg the standard starter's range. Just make sure that if for whatever reason it's not labled, your friend has his facts straight, so you can properly gauge how much you may need to adjust during your cycle. most importantly Do some research on SERMs, aromatase Inhibitors, and HCG, and make sure that you
put a plan together with what you find. Make sure you have everything you plan on using during PCT already in your possession before starting, don't let anyone rush you into anything
just because they swear everything should be fine.
