Well...I'm certainly not modest...it's against my beliefs...anyway, Benadryl will upgrade beta-receptors, but ketotifen is good for other stuff, especially pct...here's why:
Ketotifen lowers levels of the cytokine Tumor Necrosis Factor-alpha (TNF-alpha), which is a catabolic hormone, and this is a property that Benadryl does not have to my knowledge. TNF-alpha lowers both testosterone and IGF-1 levels (3)(4), and strenuous exercise elevates TNF-alpha levels (5). Ketotifen's anabolic effects seem to be overshadowed (rendered inert) by anabolic steroids (1), however, so I reccomend it only during pct.
