Method Hydrogen Sulfide Method help

[Fire&Ash]

I'm able to find lime sulfur off Amazon. I can't really find hydrochloric acid. I think it's toilet bowl cleaner but the toilet bowl cleaners I see like Lysol idk what the percentage of HCL are. My questions are
1) what concentration of HCL do I need? I found 37% on Amazon
2) what products can I find on Amazon to get HCL?
3) do I need 150ml or 500ml each product to mix into hydrogen sulfide?

I already know the dangers of this method. I have an old beater in the back of the property that I will seal off with duct tape etc

PPH 2022 suggests mixing 500 ml of lime sulfur with 500 ml of concentrated hydrochloric acid for a confined space like a car.

35 - 39% hydrochloric acid is generally considered concentrated. At so high concentrations, hydrochloric acid is a fuming liquid that actively releases gaseous hydrogen chloride, which is a highly corrosive and irritating gas.

The reason why concentrated acid is recommended is probably because it can react with lime sulfur more quickly than a dilute acid, thus producing H2S faster. A smaller time of exposure to low concentrations of H2S before reaching high concentrations of H2S (that effectively produce unconsciousness) implies smaller chances of experiencing some bad symptoms from inhaling the gas. But the presence of high amounts of hydrogen chloride released from concentrated hydrochloric acid into air may overweight the benefits of quick production of H2S due to discomfort caused by inhaling HCl. So whether concentrated hydrochoric acid is optimal for preparation of H2S is questionable.

It's also remarkable that whenever you open a vessel containing a concentrated hydrochloric acid after it was closed for a long time, a lot of pressurized hydrogen chloride is released immediately, forming a highly irritating cloud around. This is why I'd recommend to open containers with hydrochloric acid outside of the car or whatever confined space you're going to use.

The best techniques of H2S poisoning (causing the least discomfort) would use producing H2S by reactions like Al2S3 + H2O or Na2S + H2SO4 with further adminestering of the gas via a face mask or a plastic bag.

You may be better off doing iron sulfide with sulfuric acid. There won't be any Chlorine gas produced this way, so you'll not only have less suffering but also a lesser chance to attract attention (Chlorine's distinct color and smell is more likely to get people alarmed).
