Coming back to something from earlier in the thread, because it keeps being talked past:

Red flags, in rough order of how much they should worry you: no verifiable address, no batch numbers, prices far under market, vendor-commissioned tests only, pressure toward irreversible payment, and shipping with no temperature control.

Correct me if the detail matters more than I have assumed.

Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

Happy to go further on any of that.

A narrower follow-up, since the general answer is now clear:

How long did you give it before you decided it was working?

Moderator note: two posts asking for a source have been merged into one. Please search the thread before asking again. Thread quality here is what the rules are for. Keep it up.
