I have a bottle of Forma Stanzol that I purchased about a year ago. I actually used it on my diesel 2.0 cycle, during cycle and for pct, great product. My thing Is I am planning on running another diesel cycle in the next couple weeks and want to know if an opened bottle of Forma Stanzol would still be good up till now? Its been closed with the cap on it ever since I last used it, and its been in a cool dry place ever since I received it in the mail. Any ideas would be great, its more than enough to run another cycle on and on pct as well so if it s still good I'd rather use that instead of buying a new bottle. Cheers.
