I have been running nicotine for five years and the honest summary is that the effect is smaller than the internet suggests and real.
Read methods. Not on nicotine but the pattern is familiar.
Stupid question: how do you know whether what is in the vial matches the label at all?
How long before you can reasonably say something is or is not doing anything?
Read the methods section. It is the only part that says whether the conclusion is allowed to exist.
Name the active ingredient, not just the brand. It makes these threads searchable years later.
Cold storage, light protection, date on the vial. Boring, removes half the variables.
What is the first thing you would read if you were starting from zero?

Loose evidence is not nothing, but a washout either side is the only reason to trust your own take.
Underdosing and tolerance are indistinguishable from the inside, and everyone picks the flattering explanation.
Read methods.
