Could Vyvanse cause Blood testosterone decreased - eHealthMe.com

Not sure it would stand. I want to hope "not" as the make-up of individual drugs, even of the same sub-type do differ, and doc's dole this out quickly. I did happen to see that study and discounted it due to the low volume of affected participants. Just too many variables in life to pin point it directly to Vyvanse in that study, imho.

Interesting stuff Simon. If you run across more let me know please. I'm very interested as my son was on it for a short period of time.
