The chemical name for Stearylamine is Octadecylamine. Here are a couple of links to buy it:

But reading the MSDS I'm a bit concerned about handling it:

L-Propionylcarnitine can also be found here:

The sonicator used in the patent is SONIPREP 150 ULTRASONIC DISINTEGRATOR which is sold on eBay for $700. However, we don't need to use this one exatly. In the patent it's stated that the compound is placed inside the solicitor and submitted to 25 sonication cycles. Each cycle is composed of 5 seconds of full power sonication alternating with 2 seconds of rest. There is not mention of frequency and amplitude settings. I think maybe we can find the max settings possible on SONIPREP 150 to find out about the frequency and amplitude. Also, they use PCS and TEM to characterize the liposome. Unforttnately, I don't live in the city that I did my gradaute studies otherwise I could use thier TEM.
To avoid stability issue I think we should make small batches (i.e. supply for one month at a time).
