Been reading a lot on here about people aspirating and many people not aspirating for years and having no problems. I used to think that aspirating was only important to prevent a bubble from going into a blood vessel - I’m very new to TRT so didn’t have a very good understanding of injections. So yesterday I gave a shot into my vastus lateralis and noticed a bubble at the end…so before injecting the bubble I aspirated and blood came into the syringe. I withdrew the syringe so the bubble wouldn’t go in. I was annoyed that I wasted 0.02 mL but then I read several articles about what actually happens if you inject testosterone into a blood vessel. I basically wasted the entire thing. All the testosterone very quickly travels to the liver and gets metabolized instead of going to muscle receptors. I inject every 3.5 days, it’s been 24 hours and I feel like shit whereas normally I’m booming with energy. Sucks but I learned a valuable lesson and luckily no ill effects. I think everyone should 100% aspirate in the beginning, takes a second and there’s no downside. Hopefully someone else can learn from my mistake.
Yea just cause you got a little blood does not mean you were in a vein though, you just went through a blood vessel.
I haven’t aspirated in a long, long time. Kaiser Permenente did a study and found that since most people do not aspirate correctly, even nurse’s, that your likely to cause more damage aspirating therefore it is not necessary.
Hope this helps.
You’re injecting into muscle tissue, not veins.
It was a 27g 0.5 inch needle so it’s possible it went into a vein? I’m done rotating between stomach and quads, quads cause a lot of soreness afterwards and the injection usually burns. I think I’m going to try stomach/love handles only from now on. I guess overall, my concern isn’t with danger, just not wanting to waste testosterone. I definitely don’t feel like I had my regular fix.
Not if injecting in the outer quads or shoulders, you would have to inject in an area where there are veins like when you draw blood. Nurses always give vaccines in the shoulders without having to worry about injecting into veins.
I have certain places in my quads that hurt when I inject and other places that do not hurt. If I inject too far forward closer to the knee, it hurts, if I inject in the middle, I feel nothing, but if I inject too far up the quad, it hurts.
If you not taking advantage of the ventro glute, your doing it wrong 
What kind of damage? I normally aspirated in my quads because it’s stupid easy and just give me peace of mind. A couple days ago I injected my right quad and caught my self playing around with aspirating. Seeing how many bubbles I could get and just watching and looking, being a bored dumb guy basically.
Since then my quad is absolutely killing me. I’m even walking with a limp. It’s like somebody punched me really hard in the quad. First time it’s ever happened and wondering if this could be the cause after reading what you wrote.
It is probably more due to incorrect needle placement.
