I am not a doctor but- It has a weight scale on the side of the dosage syringe. Just do the math. Also the chart for usage is on the FLCCC website. https://covid19criticalcare.com/ivermectin-in-covid-19/how-to-get-ivermectin/

"Yes, the ivermectin in both formulations is pharmacologically equivalent, however there is a difference in the amount of impurities contained within each. The human formulations have highly regulated and thus very low levels of impurities. We cannot recommend veterinary formulations given the lack of safety data around their use, however we are also not aware of any associated toxicity. Liquid veterinary formulations intended for subcutaneous administration have almost no impurities and can be administered by mouth and thus are likely a safer product. However, the FLCCC does not recommend veterinary formulations and instead emphasizes the critical need for our leading health care agencies to approve and recommend use of human formulations to health care providers."
