In propionic acidemia , a rare inherited genetic disorder, propionate acts as a metabolic toxin in liver cells by accumulating in mitochondria as propionyl-CoA and its derivative, methylcitrate, two tricarboxylic acid cycle inhibitors. Propanoate is metabolized oxidatively by glia , which suggests astrocytic vulnerability in propionic acidemia when intramitochondrial propionyl-CoA may accumulate. Propionic acidemia may alter both neuronal and glial gene expression by affecting histone acetylation.   When propionic acid is infused directly into rodents' brains, it produces reversible behavior (., hyperactivity , dystonia , social impairment, perseveration ) and brain changes (., innate neuroinflammation, glutathione depletion) that may be used as a means to model autism in rats. 
Salmeterol : In a drug interaction trial in 20 healthy subjects, coadministration of inhaled salmeterol (50 mcg twice daily) and oral ketoconazole (400 mg once daily) for 7 days resulted in greater systemic exposure to salmeterol (AUC increased 16-fold and Cmax increased -fold). Three (3) subjects were withdrawn due to beta 2 -agonist side effects (2 with prolonged QTc and 1 with palpitations and sinus tachycardia ). Although there was no statistical effect on the mean QTc, coadministration of salmeterol and ketoconazole was associated with more frequent increases in QTc duration compared with salmeterol and placebo administration.
The side-effects of Testoviron are identical to all testosterone compounds, and largely surround this steroids strong aromatizing nature. This can lead to gynecomastia, excess water retention and even have a negative impact on your blood pressure. Further, like all testosterone compounds, Testoviron can have an adverse effect on LDL and HDL cholesterol levels, but all hope is not lost as the side-effects are easily avoidable for the healthy adult male. In-order to achieve this, you will need an Aromatase Inhibitor in-order to combat excess estrogen caused by the aromatizing process. Further, controlling your diet and dosing will do wonders for your protection; in-fact, if you do these things there’s no reason for a healthy adult male to have any serious issues.
