My advise is to accept the current offer too, because you'll never know if Lonza will give you an offer. Only when Lonza offers you a position, then you decide on your next move.

Is the condition at NCC really bad such that you're considering to leave after 6 months? Because if NCC is your first job, my advise is to stay a year or 2 at least, else you'll look like a job hopper.

Considering long term, my advise is to try to shift out of life sciences/biotechnology. Because it is true what they say, without a PhD, you cannot go far. Plus the industry does not pay very well compared to other industries. I'm a life science graduate myself.
