Gymbeam experiences?

I'm in the EU and while looking around for supplements I found the website Gymbeam.

I bought a pack of creatine since they had a decent sale, and I noticed that their "Gymbeam" brand adaptogenics (the ones I'm referring to are bacopa, rhodiola and ashwagandha) have suspicously low prices for the dosages they offer.

Does anybody know if they're a decent manifacturer? Have there been any lab tests on their products?
