This is emphatically not an equivalent to a commercial epinephrine auto-injector.
Point 1: The Autoinject 2 used in the instructions is made to inject at a different depth than the epinephrine injectors (subcutaneous vs intramuscular). This will change the effect of the medication administered.
Point 2: Epinephrine solution cannot be drawn up manually into a syringe and left for use at an indefinite future date. Nursing team advice recommends discarding manually pre-loaded syringes within 12-24 hours (to say nothing of the difficulties of maintaining proper sterile technique).
And finally, Point 3 (which was a red flag to me): “Doctor” Michael Laufer (as he refers to himself in the video) is not an MD. His PhD is in mathematics. He says as much on the site where the “Epipencil” instructions are hosted (fourthievesvinegar.org/faq) and admits it freely on Twitter as well. He does not have the health care experience to appropriately advise use of this device.
Use a different company’s commercially available epinephrine auto-injector - AFAIK they’re pretty much all cheaper and work nearly as well. Or for maximum savings (albeit with some increased risk) one could have a relative train in how to properly draw up and administer an epinephrine dose in an emergency.
This works better for chemo and insulin-dependent diabetes because it can safely be assumed that those doses will be drawn up and used immediately. Setting this up with epinephrine and then just leaving it aside for future use could have all kinds of bad effects, up to and including death.
Also, the Four Thieves reference? Also concerning in the way that Laufer calls himself “Doctor.” It was a medieval nostrum that claimed to ward off plague infections when one was exposed - pretty much pseudoscience and wishful thinking. https://en.wikipedia.org/wiki/Four_thieves_vinegar
