When will your Rhodiola Rosea 3% Salidrosides be back in stock?

I cannot give you a firm date yet. We are working very diligently on it, though. There have been a lot of supply issues in China, due to the government there shutting down hundreds of suppliers. So it is creating a supply issue, and some suppliers are turning to misbranding things to keep up. That's what happened with our resupply shipment. After testing it in the lab, it was found to not be Rhodiola rosea, but was actually Rhodiola crenulata. That is a different species, and contains no rosavins. So we rejected the batch, and are trying to source real Rhodiola rosea now.
The thing with Rhodiola crenulata is that it is cheaper, so some less scrupulous suppliers just relabel it Rhodiola rosea. It also does contain salidrosides. So HPLC testing will pass if that is all that you are looking for. However, it will contain no rosavins. So you will see the lack of a peak there on the HPLC. Also, we HP-TLC test all our natural extracts, which can pinpoint the exact species and plant part used in an extract. That's extra confirmation you are getting the exact extract you are supposed to.
