I was just curious as to how long this bottle will last. I had to break into a new bottle to get the correct amount for this shot. So the seal is broke and I've already stuck a needle in it. So can I save the rest for my next cycle in a few months or just use it now? I'm on wk 8, 750 a wk split into two shots. Sciroxx Enanthate 250. Any tips would be great.
