I bought some liquid nolva from a R-Co. and I can't keep crystals from reforming every week or so. The supplier sent me directions on how to fix the problem but the crystals keep coming back after I reheat the solution. I have read others tell people to boil the vial instead of using the oven and wonder if that would give me a permanent fix. Do you guys think the crystals reforming could be a sign of a bad batch?
Thanks
