Would you really trust a Chinese source? How would you know what you were getting? How would you test it's purity? How could you get your money back if they send you sugar?
OK. For starters, the pure alagebrium is absolutely sparkling, crystalline white, like freshly fallen snow. Any hint of grey, yellow, or brown is impurity.
Second, it is highly soluble in water, and also absorbs moisture from the air. You can set a spoonful on the scale and watch it get heavier by the second as it absorbs moisture from the air. So you want to keep it stored in an airtight bottle with a silica gel packet. Store it in the dark, not in direct sunlight. For long term storage, you can freeze it for years, but let it come to room temp before opening the jar, to avoid condensation.
If you want drops, you can easily mix 100 mg/mL, or even 200 mg/mL in distilled water (water from the Glacier RO machine works fine) or even vodka. It is more stable in distilled water than in vodka. But it is much more stable as a dry solid, kept in the dark.
To test composition, you can do a melting point test. It melts very sharply at around 219-221C with decomposition to a brown or black substance. If you see a broad melting range, it is not pure. Because of the decomposition, you need to raise the temperature rapidly so that you will see the melting before it decomposes.
You could also have more expensive tests done (HPLC, Mass Spec) if you are buying a large quantity.
The taste is extremely bitter! Even with a dropperful of 100 mg/mL solution, you would want to dilute it in a glass of water or grapefruit juice. Or else make capsules.

I know several people who have taken 100 mg/day of pure alagebrium for 14 years.
I hope this helps.
any news in the past year?
