Are ECA stacks really T5 diet tablets or are they fake?
ECA Stacks are different to T5 diet tablets in many ways. The traditional ECA stack contain Ephedrine, Caffeine and Aspirin, they do not contain T5. This type of traditional stack does not increase T5 levels within the body. There is a modern type of ECA stack which more properly should be referred to as an ACA stack. These stacks contain an Alkelite on its own (as in the case of XTR) or a combination of Alkelite with Caffeine and Aspirin. An Alkelite is a natural substance that is known to optimise thyroid production, and is therefore often prescribed by doctors as a first step in the treatment of thyroid conditions. Some athletes combine this with Caffeine and Aspirin to produce a home brew ECA/ACA stack. ECA stacks are not properly T5, however modern alternatives contain an Alkelite which is known to optimise T5 production.
