Yeah, thats fine your just squirting it in your mouth anyways so sterility is not a big concern.
One thing to consider, if your on ana and gyno symptoms start you need to up the dose, but you still want nolva on hand because gyno signs are generally because the estrogen, igf-1 or prolactin levels are allready to high. ANA prevents the aromitization, and if your curent dose is not cutting it and you get symptoms that means you allready have an excess of one or more of the above and just adding more ana will not reduce current ER, IGF-1 or PRO levels only prevent more from being created.....if that makes any sense.
