I have both a cattle prod and a TENS-7000. I assume there may be different voltages and pps that work best on different wounds and there must be a database that would be used to track results for everyone that self experiments. One study only applies to its small set of masochists. I would like to see the numbers evolve over time from more masochists so we can share each others pain, pleasure and recovery. Also the best places to stick it and results of different molecules to work in conjunction with the TazeMeBro-20000. e.g. Terrasil3X vs Max strength Desitin vs other off-label options and other supplements. Diabetics seem to prefer Terrasil3X. The step-by-step guide should have videos of unclothed people configuring and applying the TENS to every possible wound location.
