I have bought the old sarzi several times without problems, but the last order arrived with the new sarzi (EXP 15.3.2027)
According to the information on the Brainmarket website: Due to the change in raw material, the powder is now green instead of the original white colour. It's not a glitch. The product now contains 38% L-Theanine. The product therefore contains much less active ingredients, but this is not clearly declared anywhere. It also contains caffeine: Our green tea extract, in addition to L-Theanine, contains other bioactive substances, which means that it also offers almost 9% polyphenols and 6% catechins. It also naturally contains caffeine, 2.25% or 4.5 mg per 200 mg serving, which is roughly 1/10th of the caffeine in a regular cup of green tea. I used to use it as part of a "cocktail" before bedtime in combination with gentian and apigenin, but now it no longer works. I still have the rest of the old sarge and the difference is noticeable.
before the composition change super
change of composition and content of active ingredient, but the price is the same
the new is not pure L-theanine, deceiving the consumer

I used to buy and be happy, now it's a scam. They diluted the active ingredient with green tea powder, but there is no mention of it on the packaging. You are paying for a much weaker product than they declare.
Misleading the consumer
The contents do not correspond to the composition on the packaging
Diluted mixture instead of pure extract
Lower active ingredient content
Concealed recipe change

tastes good, can be dryscooped, can be mixed into a drink, I mixed with energydrink for example, then I had no problem sleeping at night.
price
the second order has a completely different content, taste, consistency, colour (reminds me of matcha), so I have doubts whether the information on the label can be trusted.

For me, it has worked well to take it every day during the period when I drink only coffee (not tea) during the day. Raising the levy didn't help.
really improves sleep, sometimes quite significantly
I'm developing a tolerance for it: when drinking tea in the morning and taking theanine before bedtime, the positive effect on sleep completely disappeared
with regular daily use (or higher doses) it may increase my nervousness/anxiety
