The good thing is, if some contamination were to occur, subq will be better than IM, if you wipe the rubber with alcohol i think chances of contamination are really slim. Are you injecting in stomach area? Would be interesting to see what kind of blood levels you are getting, please post results if you end up doing labs at some point.
I do inject in the stomach. And I do wipe the rubber with alcohol swabs. I will post blood levels when I get some. A couple of more points on this topic:
I have also had the same concerns as others on this thread on what is best: Keep my original vial of Nebido for three weeks, draw twice per week and inject - or draw six syringes immediately, store the syringes in the fridge, and replace the needle just before each injection. One doc I consulted with said his guess would be the latter option would be better. That's what I currently do.
Another point: Several comments have been made on this site on the problem/advantage of Nebido's very long half life. Some saying that injecting frequently would counteract or nullify the benefit of the long ester. If that refers to nullifying the convenience of not needing to inject frequently - then yes, of course. But with that logic, why inject T-Cyp every day? Why not every second day? Or twice per week? etc. Because no matter what half life, the more frequent injections, the more stable levels of T (and E). So the logic for frequent injections will always be there, no matter how long the half life is. Doing Nebido the 'intended' way, every 10-12 weeks, creates an enormous roller coster. Resulting in at least double the levels at the peak vs the trough. Probably three times higher for some. I.e. drops peak to trough by 50%-70%. By knowing the half life, one can wtih a reasonably good accuracy calculate the max and the min levels based on various injecting frequencies. Doing 12 mg of T-Cyp each day would give a drop peak to trough of about 9.5%. Doing weekly Nebido would give about 12%. So if we think the golden standard is daily T-Cyp, we would need to inject more frequently than once per week with Nebido to reach the same level of stability. Twice per week Nebido would give around 6.5% drop peak to trough. So in my opinion, disregarding potential issues of cleanliness, cost, etc - doing Nebido with at least two injections per week is a damn good way to achieve very stable T-levels (and hence E levels which probably is just as important). If we think the stability achieved by daily T-Cyp injections is worth the hassle of daily injections, then we should happily accept only two injections per week of Nebido to achieve even less fluctuations.
Of course - if someone feels great at the more traditional frequency of Nebido injections - then why change it. After all, if we could achieve desirable results with less injections, we all would choose that. But in my case, the difference (so far) between the high frequency (twice per week) and the lower (once per month) frequency has been enormous.
Furthermore, the long time it takes to achieve steady state with Nebido, can quite easily be dealt with by some maths. Again, knowing the half life, we can do some solid estimations of how to ramp up to the blood levels to steady state of any desired protocol. Equally easily we can calculate how long break to take to get down to steady state levels of a desired lower dose. E.g. to start from scratch on my current 0.2 ml twice per week, one would inject 2.7 ml Nebido on the first Monday, and then just start doing 0.2 on each Thursday and Monday. Since Nebido peaks in a week (or even less according to some papers), we would reach the steady state very quickly with that approach. That's of course based on starting with nothing in the system, which we would only do when getting on TRT initially or when switching from something with extremely short half-life (e.g. gel).
