Old T2 and MD6:how to recognize and use them

I think that I’ve bought some old T2 and Md6 from my shop.I live in europe so maybe the shop’s stocks aren’t out of those products.
Any guess on how discover the production batch for sure?Should I change the way of using them?How?
Thanks for your help

The ingredients are different. The old T2 had one ingredient: diiodothyronine (3,5-diiodo-l-thyronine). The old MD6 had the following ingredients (from an old BTS article):

Contained in each 2-capsule serving

L-tyrosine
200 mg

Alpha lipoic acid
200 mg

Guggul extract
200 mg

Caffeine
100 mg

L-norephedrine
25 mg

Yohimbine
5 mg

As far as I know, label directions have not changed, so the current recommendations for T2 and MD6 still apply.
