TENKAIWICK 150 Pack 29 Ga 0.5 Inch Luer Lock,Lab Accessories, Industrial Dispensing Accessories, Individually Packaged

Pretty poor batch. Quite difficult to draw liquid and I’ve lost a few needles as they don’t push the liquid and cause the needle to detach from the syringe.

I bought these once before and I should have bought a different brand this time, but i gave them another shot. They're economically but I don't think they are sharp enough, and the sharpness varies between needles. I've had one that wouldnt penetrate at all, i had to swap it for a different one. It sucks because they're so much better than insulin needles because you can swap needles without having to transfer your solution and theres like a flashback area where if fluid comes into the syringe it first fills pockets in the needle, so if you made a mistake or the needle clogs, you can swap it out without contaminating your whole solution or having to waste it. But yeah, those bevels be jagged and raggedy.

Too fat for repeated injection

So far so good...I use the 23G to Draw the TRT Juice and just the 29G to Pin my Deltoid. Exactly as advertised....

Very sharp. No pain whatsoever.
