As @randy says. Also, make sure they tested more than 1 vial, or test a few yourself. There can be quite a variance from vial to vial, which can make dosing difficult. Try to find kits that have had more than one vial tested, and the variance between vials is small.

@DarkStar you don’t want to push the rubber stopper on that device that’s not what it was made for. If there is uneven pressure the rubber stopper can get uneven and then you break your pen. Ask me how I know. Just use the pen. No need to reinvent the wheel on this one. I do appreciate trying to come up with some knew or better way though.

The glucagon portion of Reta is your most likely cause. It all depends on your tolerance. Let is play out and maybe it'll get better or lower and potentially drop and switch to a different GLP.

@denti For a Lipo-c shot, it might be difficult to push through that small of a needle on a pen. I've tried using a 30g needle on an 1cc syringe and that was so hard to push the plunger. But depending on the concentration of L-Carnitine you have in your vial of Lipo-c, will determine how thick it is.

@denti same here

@emkay Same for me. I originally bought it for the vial labels, but I'm using it for so much more, work, household etc
