Where to buy Glucardiamide and what substitutes does it have?

I enclose information about the availability of Glucardiamid in pharmacies integrated with GdziePoLek, but it is very small at the moment: https://www.gdziepolek.pl/produkty/33269/glucardiamid-pastylki-lamelki-zelki/apteki In March, we received information from the manufacturer that the drug was withdrawn from the portfolio due to a problem with the availability of the active substance necessary for its production. It will only be available while current supplies last. Glucardiamide has no exact replacement. Suggestions for products that can be helpful in states of fatigue and weakness can be found in the following materials: https://www.gdziepolek.pl/artykuly/nasze-sposoby-na-zmeczenie https://www.gdziepolek.pl/opinie-i-pytania/101941/co-moge-zastosowac-zamiast-glucardiamid-przy-znuzeniu-oslabie
