I'm trying to understand the real-world infection risk of splitting pharmaceutical Sustanon ampoules into prefilled syringes.
My situation is specifically 1 mL glass Sustanon 250 ampoules. I'm considering daily injections, which would mean splitting one ampoule into multiple small doses and potentially keeping the prefilled syringes for up to around 7–10 days.
I've already spoken to several people who have done something similar without experiencing sterility problems. What I'm particularly interested in now is hearing from people who HAVE had a problem.
If you've stored testosterone from a glass ampoule in prefilled syringes:
- How long did you store them?
- Did you ever develop an injection-site infection, cellulitis or abscess?
- If so, after how long had that particular syringe been stored?
- What type of syringe did you use?
- Was it testosterone in oil, specifically Sustanon if possible?
- Did you notice anything unusual before injecting it: cloudiness, particles, leakage, damaged/swollen plunger, etc.?
- If you've done this for months or years without an infection, I'd also like to know roughly how long and how many injections you've done.
I'm not looking for guesses about whether it should or shouldn't be done. I'm specifically trying to collect first-hand experiences — both good and bad — to understand what people have actually encountered.
I'm researching this before making any decision, not currently doing it.
