opitates arent toxic like superdrol.
They are for shure not good for you long term.
Main Side Effects: Bad Constipation, Lowered Test, Dependence and increased dosage requirements.
Id say superdrol is more toxic than most opitiates by far, probally not herion and the stronger ones.
You cant keep taking superdrol without severe health consquences, while something like Oxycodone/oxycotin can be used for pain management pretty much for years upon years for chronic pain. You cant take superdrol for years, your liver would fail, and youd die.
If you take opiates occasionally it wont effect your test to the point of inhibiting gains, id say once a week, as an estimate.
A lot of people on chronic opiates actually have a need for testosterone placement therapy, almost all men.
I have no backing of this particular hypothesis, but perhaps a small/regular dose would affect your testosterone, only for it to bounce back higher. I have no evidence for this. But the idea is interesting to see, there are no studies on this. Just some idea i came out with. Dont take it for fact, merely something intriguing.
Also you'd be suprised to find out a number of Pro-bodybuilders use oxycone for pain management,since it only has indirect affects on muscle loss, through testorestone modulation, while something like Tylenol has direct muscle inhibiting effects. Also once they start injecting themselves with anabolics, its not too much of a stretch to inject themselves with other substances. Plus there already taking enough steriod to make their own test production pretty much crap, so opiates really couldnt lower it much more.
The occurence of this I am unaware.
I have read one or two underground,anonymous articles about this, plus a reference in a movies plus, people who deal one drug, a lot of times,deal others.
