Considering the fact that we have no clue what your condition is, let alone how in any way shape or form the intravenous route is ever HEALTHIER, no matter what obscure drug you're injecting for whatever undisclosed condition you're treating, because you have to inject it in no way means that you are being healthier, you are still at all risks of IV drug use, since you are using intravenous drugs, it really doesn't matter what the drug is whether it even gets you high or whether it's interferon, the IV ROA is never the healthiest option, and I've never heard of any condition that fits the criteria you have given so far warranting IV-only use. It may be the way it's prescribed to you but in no way does that mean it's healthier for you.. If there are alternatives, you should seriously be using them. A drug you can't even administer yourself yet competently, I don't even know how anyone would think it's safe while you're still learning the basics of intravenous administration, and prolonged extended use of this ROA especially when performed incorrectly, will RAPIDLY lead to your inability to find an IV site when you really need one, and you do NOT want to live with a IV catheter or PICC line....
And fuck using any materials during INTRAVENOUS DRUG INJECTION that I didn't open from a trusted sterile place, I've never used a needle that wasn't my own, never shared solvent rarely ever shared solute and have gone to extreme lengths to use the IV ROA strictly by the medical textbook, and EVEN STILL, I assure you, in the long term, this is not possible, let alone healthy... let alone healthier than alternatives.
