Well you're right, Elite has critical collaborations with its good friend Epic and with SunGen... two of the largest pharma companies in the world with extensive portfolios and R&D programs... go Elite!
Here is the link for all FDA-approved opioids with AD label
Which, in order to get the AD label have had to perform and submit CAP and HAL studies.
as for how "Impressive" Elite's results are... well, Sorry I'm not that easily impressible.
The Opioid/Antagonist approach obviously works to deter abuse and dimish drug liking, as shown by the already approved Targiniq ER, Embeda, Hysingla ER, Troxyca ER
If it comes in one or two or six beads... well, moo point ;)
We mortal newbies are thankful for your consideration! :) I'm glad only those who are critical of Elite and not happy with its performance get call for BS while all those DollarLand and Billionaire Platforms keep the room stinking of bull poop :)
