Ill add to what the others have said on the topic:
I have always mixed oils instead of doing separate injections/ also mixing orals is a very common practice known as stacking.
There is the inherent danger of combining compounds which are VERY closely related, which may mean one should adjust dosages or avoid certain combinations:
Example Jony Juicehead, is one 500mg of test E per week, he wants to put on a ton of size, so he talks to a buddy who gives him some left over DBOL, that’s great and good, however if Jony continues to keep the same dose of Test E, while throwing in say 50mg dbol, 99% of the time he will RAPIDLY develop Gyno.
Both of these compounds aromatize at a very high rate, jony needs to lower his test in order to avoid getting double the estrogen sides he would have on test alone.
Similarly if jony used anadrol and dbol together he would very likely get gyno within the first week.
Other pitfalls are using two drugs that are highly hepatotoxic ie androl and halo.
Or none sense combinations like test E and Test C
Not dangerous but totally a waste of money.
