Yes this is a well known problem of generic medication and the countless problems with it because of cheap excipients.Without exploiting the Oxy topic any more. Isn't it possible that people react differently to the filler? Does Oxy's use fillers in its manufacture?
Personally i had the problem with T3 from Hilma. According to the lab test, the Hilma T3 was dosed correctly, but my blood count showed no reaction to the thyroid markers. I responded better to the T3 from Deus. Both are T3 and both correctly dosed according to Jano. I believe the filler in the Hilma T3 is to blame for my body not metabolizing it properly.
Is that possible with Oxys?
