Anabolic were developed for humans they have been tested and approved as prescribed medications to treat a variety of ailments. People have been taken large amounts of anabolics non stop for decades the last 50 plus years without ill effect. This was absolutely not from anabolics. This was from recreational drugs, pesticides(dnp), Research peptides(aditope or whatever it was), diuretics and synthol. That shit killed his liver not Test and Deca even at 6g a week.
As one guru says, there are no bad drugs. It depends on the situation and dosage. Just because something is a "pesticide" doesn't mean it's necessarily always bad. DNP was taken off the market for one reason only: eye cataracts. Theoretically DNP could sometimes be used to fix certain health issues.
Synthol shouldn't be toxic in any way. It's medium chain triglyceride which is basically harmless. If it were toxic you would never eat coconut oil or whatever with MCT's. Synthol is bad for your muscle tissue though but it's not going to make your kidneys fail.
Anabolics can be, and are, directly kidney toxic. It's all in the dosage, duration and also individual susceptibility. I don't know how much you know about Bostin but he used 13 GRAMS of gear a week as a teen! It's unknown if his kidneys failed from the adipotide. Who knows if it even was the correct compound. Some of these lyophilized products have been completely bunk or the wrong compound. 13 grams of steroids IMO could fuck you up quickly
Not all recs are bad for your health. You smoke weed. Bostin said something about doing acid recently. Not really physically dangerous. GHB isn't very toxic, the danger is in the addiction. Occasional use, harmless. Opiates as far as I know aren't really toxic, though I might be somewhat mistaken here. But occasional use isn't organ toxic really. Tylenol is way way more toxic.
