No there not the same T3 and T4 the difference is strength 30-60mg
Vicodin is a synthetic opiate....hydrocodone in stead of codiene....
codiene is easier to get off right if your only taking 2 t3 a day. but it been 5 years everyday . big difference between t3 and hydro right strenghth wise . hydro probably worth about 5 t3 in one.
