The risk: Someone claims something helped them, others buy something vaguely similar in hopes of getting the same experience and then get worse. Maybe the substance really wasn’t for them, or maybe they used an inferior product and (wrongly) blame this on the entire substance in question.
The flipside: Someone tries an inferior product, has something bad happen then puts off others from using something that may potentially help them. So for example, listening to some guys here, I would never try Tribulus and would be in the same sh**hole as I was in 2018.
I think if we’re going to be fair, you need to disclose what you used and if you used a different brand or type of product from the one reported to work positively then that needs to be said. Otherwise with all due respect, not much more can be inferred from your statement other than “I used (some) Tribulus brand and it made me worse.” It doesn’t say much about the substance in general, only about the particular brand you may have used. And as even scientific studies have shown, the protodioscin and saponin content varies greatly depending which part of the plant was picked, and in which part of the world it was grown. It is almost as vague as saying “I ate some red berry and had a diarrhea, hence berries are bad”.
