I have been using an Advair inhaler twice a day for about a month now (250mcg fluticasone propionate/50mcg Salmeterol). The fluticasone is a corticosteroid and the salmeterol a beta-agonist. Would this hae any negative/positive effects on gains? Althougth the Corticosteroid is a smaller concentration would this effect muscle growth or make it harder?...I am not on any AS. Just high protein, glutamine, creatine, and soon 1-Test (or related compound)...could the salmeterol help gains?
