The bottles will be perfectly fine. Its a truly great product but overpriced. I buy expired bottles of Dicana at half price all the time from Vitamin Shoppe (**when they get within 3 months of expiration they are put on the sale bin at half price.) I buy 2 bottles for $50 and double the dosage @ 2 pills 3x a day with a taper down which last about 5-6 weeks. Take it on an empty stomach.
If you have the cash it works very well with ephedra, venom, amp, stimulant x.
I generally like to run Designer Supplements Melting Point and USP labs Camphibolic post cycle for Thyroid support and they can be bought quite cheap too.
At double the dosage, it is about 3/4's as potent when compared to Tiritricol/Triax/Tricana. But about 1/2 - 1/3 to T3. However, I have to say I like Dicana better than T3 because it doesnt eat muscle as much and allows your muscles to remain full. Its not for major fat loss like T3 or T4 but great for recomp while keeping your hard earned muscle in tact.
