Users report blocked needles during draws despite correct technique, with some tracing it to bad stoppers or strong vacuum in vials. Suggestions include venting by adding air first, using larger needles for reconstitution, checking plunger movement to test for blockages, and drawing slowly after centering on the stopper. Overdosing incidents are linked to unnoticed blocked needles or missing glasses during mixing.
What this discussion establishesWhether the problem is mainly faulty needles or vacuum and stopper issues on the vials themselves
Nothing here is advice.
Hi everyone. Tried my weekly shot and ended up going through five needles total. One pulled the bac water into the peptide vial but then nothing would come out when drawing for injection. Swapped to another needle and still nothing, tried a third with the same result until the fourth finally worked. This happened once before and caused me to take double the intended amount because a couple of needles were blocked. These came from a different brand than before and I can't recall the previous ones since I put them away. Any recommendations for syringes that avoid this problem from the UK? The overdose time happened because I wasn't wearing glasses and thought the bac water had gone in when it hadn't, so only half the amount was added and the vial ran out quicker than expected.
I searched online for ways to mix those compounds and pull liquid from a container. I viewed plenty of separate clips on the subject. After that I asked an artificial intelligence to explain each method in detail. I made sure my spectacles were on. I moved slowly so I wouldn't need a hospital visit. Everything worked out fine.
Something similar happened to me last night with my reta. When trying to pull the liquid it only trickled into the syringe on pulling back the plunger. Tried poking again and the flow was even worse. Switched to a different brand of needle and got the same result. I think the vial had a bad stopper. Not like I'm new to this since I used to draw my mom's insulin from a vial before she switched to pens.
I know exactly how to do it all and have been doing it for two years. Never had dud needles before so didn't expect this. I don't actually need glasses but use them as extra caution to hit the middle of the vial. The time I took too much was when the bac water didn't draw up and go into the vial because I was tired and on autopilot after doing it so many times. Thanks for the suggestion though. I'm asking about needles not advice on reconstituting.
Was there a powerful suction inside the container? Did it pull the sterile liquid from the needle during mixing? In that case, perhaps you're working against the pressure. I usually add an equal amount of air to the container ahead of withdrawing the amount. That tends to resolve the issues I encounter. Based on your description, it seems you skip the filtration step beforehand?
I was talking about the right methods for mixing and pulling the liquid when I mentioned venting the container to equalize pressure before removing the desired amount.
Which needle dimensions do you prefer? I go with thirty gauge eight millimeter ones available through online shops, yet sometimes I run into issues with certain containers unless the needle hits the exact center of the cap and I pull the liquid out at a slow pace. My usual approach involves first pulling some air back into the syringe, then pressing that air into the container so the bubbles that appear confirm the tip sits in the proper spot.
By the way I go with bigger syringes during mixing which keeps everything straightforward without any trouble from the tiny versions. The bottles pull the fluid inside on their own with zero pressure needed.
Already tried every step suggested. Four needles have failed completely so far with nothing entering them at all. I draw back and force air into the container yet still no liquid reaches inside the needle. Maybe the container itself is the problem just like the earlier comment noted.
Yep I've got some like that where bac water just gets sucked into the vial sometimes with too much force.
I take out the plunger first before injecting. When it moves upward without resistance, that means nothing is clogging the needle. After that, I push the syringe into the container to balance the air inside. Following this, I put the plunger back in to create pressure for the volume I want plus some more. Drawing the precise quantity might require working against that pressure, yet it turns out fine.
