Taking with food depends on the type of oral steroid (c17aa)..
William Llewellyn strongly advocates - (c17aa) These compounds are highly resistant to hepatic breakdown, so you don't need to sneak small amounts through the lymphatic system with dietary fats. That may only hinder full absorption. Exemestane, on the other hand, is steroidal in structure, but not c-17aa. Like other non-methylated steroids, it isn't as resistant to hepatic metabolism, and may be absorbed better if some fat is present.
Gastro pains are very common man, IMO it won't hurt to take with some crackers or something light, fat and protein free, I'd stay away from any protein intake before and after administration, until it has been processed to better assure a greater absorption ratio and less liver stress..
Winstrol would to do this to me, I would take it with home made ginger water..As you probably already know, ginger root has great properties..Ginger root has been the go to since ancient times for all sorts of stomach/gastro related issues..
