Parkinson’s treatment with Acetyl-DL-Leucine

Does anyone have experience with the dietary supplement Acetyl-DL-Leucine? Based on a study of two patients primarily focusing on reducing REM aggressive sleep disorder I procured tablets online and after taking 5 g per day for two months. I noticed positive results for several symptoms I have now. This product is not Tanganil and is no longer available and the provider stated that they are no longer authorized to sell because a third-party company in the USA has claimed rights to sell so after researching availability elsewhere, I was able to obtain from a company in Belgium for now. I only have enough for a few months.
Any feedback is appreciated.

Respectfully,
