Structure of D9 HHCa

HHCa has a High viscosity. It cannot be pushed out of a syringe at room temperature.

Is it a phytocannabinoid? (naturally occurring cannabinoid)

HHCa is not phytocannabinoid (Not conclusive - Need more testing for confirmation on this. We know HHC is naturally occurring so I'd assume HHCa would be found naturally as well. Has not been reported yet however.)

My Opinion

Beyond looks, there really isn't anything too special here. It's a slightly stimulating version of HHC, and not a lot else. For the price, I can't recommend it other than if you are trying to make a very exotic-looking blend. I will say it is quite fun to dunk other dabs in it though. It makes a powdery crust on the dab that's quite delightful.

What can HHCa do for a blend?
  • When put alongside D8, HHCa provides a powerful initial hit that makes my face feel fuzzy.

  • Improve looks

  • The same things HHC can do

  • A slight stimulation at the beginning of the high

  • (In my personal experience) The kick from HHCa in a blend can be felt between the first 1-10 minutes of a dab.

Other notes:

It's important to keep in mind that batches of HHCa vary in quality based on R % values. Check out this article to learn more about that.
