There are no known contraindications regarding Benzo's taken concurrently with IGF-1.
Benzo's don't block Igf-1 nor the other way around. BTW, Klonopin isn't classified as a benzo, although it certainly fits the bill structurally and is often prescribed for the same symptoms as Xanax, Ativan, Valium etc. This has led many to believe it is not addictive in the same way as the above mentioned, but that is pure fallacy. The rehabs across America are filled with people who need long term care to D/C Klonopin. It still won't affect your exo or endo IGF.
