Good advice.

It sounds like your using a high grade/high potency source material, perhaps you might want to look at adding a THC pre-extraction step into your process in order to maximise the overall strength of each capsule.

Isolate the THC into a honey oil (or budder) prior to infusion with the coconut oil to increase the percentage absorption per capsule (you'll also end up with a 'cleaner' product. i.e. no suspended plant material).

I'd also try to convince you to adopt the slow cooker method rather than a 'double broiler', and get the temp over 212F (but under 280).

The type of 'one hitter' capsules your aiming at are do-able (tolerance permitting), I have quite a few myself for personal use, using the above ingredients and processes.

Good luck and keep going!
