Can I use my injectables intravenously to get better effect?
In a word, NO. It would be inadvisable to do this and may be positively dangerous. Certainly with Trimix, side-effects are minimized by the fact that you are applying the drug intracavernously and are, in fact, localizing the effects of the drug to the corporal tissue. To give the drug intravenously would be likely to cause serious systemic side-effects.
