Make an alcohol tincture imo. Find some 151 or everclear - either that or get some veggie glycerin and a tincture bottle. Don't add a ton of alcohol or glycerin...you want to see maybe an inch max over the top of your hash in the tincture bottle. Decarb your hash in the tincture bottle at ~275f for like 15 min tops. Add your alcohol or veggie glycerin. Let it sit for like a month to be safe. A few weeks should do the trick though. However if you want to speed up the process, heat the mixture on low low heat for another 15 mins. You don't want the mixture any warmer than like 175f just to be safe.

This is a super simplified method. People will come at you with soy letchin, MCT oil, coconut oil...all this complicated shit. This is easy and strong. Cooking the two together for a bit (is good but unnecessary, decarbing and suspending will suffice). 3.5 is a little low but should be fine. Ideally you'd use 5-10g for extra strength.

Hopefully this sounds alright. Let me know if you have questions.
