It was equivalent but not a similar. Now I’m on Vyvanse 70 mg, it can help me concentrate but does nothing for my TRD. I've to return on Methylphenidate or Dexmethylphenidate.Methylphenidate did not cause any increase in tumors in a very life time carcinogenicity examine completed in F344 rats; the highest dose used was roughly forty five mg/kg/d
