PANTS...
I did not want to give you any incorrect information so I will post a direct quote from a good friend, as it was explained to me:
"Tyrosine may help:
1) Restore NE levels: therefore extending the process of thermongenesis and possibly restoring the effects of ECA after the point of down-regulation (I find this helpful)
2) Restore Adrenaline and Dopamine levels: also, with the effect of balancing your sytem and ensuring a more steady stockpile of these hormones
3)Tyrosine bonds with iodine: which forms di-iodo-l-tyrosine, and iodo-l-tyrosine, which are then incorporated into the structures of T-2 (di-iodo-thronine), T-3 (tri-iodo-thronine), and T-4 (throxine)
Both kelp (idodine), and Tyrsoine, are helpful to take periodically, to ensure that you are putting your sytem back in balance, and with this, you may extend the process of thermogenesis and the manner and length in which you may take an ECA stack. From personal experience, I have found that an occasional blitz of tyrosine and kelp to be helpful in restoring some of the effects of ECA after a period of tolerance. - dantebattista"
Hope this helps bro!
