How to use a trial size properly (most people don't)
Trial sizes exist so you can find out whether something works before spending real money on it, but most people either skip them and buy the big pack cold, or buy the trial size and never actually treat it as a test. Here's how to get an honest answer out of two weeks.
Take it every day, not "when you remember"
Fifteen servings only tells you something if you take it consistently. Skipping days and doubling up later doesn't give you a fair read on whether the daily habit and the format suit you, it just uses up the pouch faster. Pick a fixed moment, same as you would with the full-size bottle, and stick to two gummies a day for the full two weeks.
What two weeks can and can't tell you
It's enough time to know whether you'll actually keep taking a gummy supplement daily, and whether the blackcurrant flavour is one you look forward to rather than tolerate. It's usually not long enough to have a strong opinion on the mushroom blend itself; most people who continue plan to properly assess that after finishing a full 1 Month bottle. Treat the pouch as a test of the habit, not a verdict on the formula.
After the pouch
If the routine stuck, the 1 Month bottle is the natural next step rather than reordering pouches indefinitely, since the per-gummy price improves at every larger size. If it didn't stick, you've spent the smallest possible amount finding that out, which is exactly what a trial size is for.
The short version
Two gummies a day, every day, for the full two weeks. Judge the habit, not the mushrooms. Step up to a bottle once you know you'll keep going.
