I'm following Noman's Tek with 50g MHRB.

Is step 10 necessary if I'm doing a re-crystallization step?

It isn't absolutely necessary. I rarely do it. Just make sure you evaporate all of the naptha.

That being said, you should try a recrystallization. It's fun to learn and it's a cool process. I also love the smell of bestine

Thanks..I plan on doing the recrystallization. I just got a bit confused because in Noman's instructions (in recrystallization section) he says:

"You will end up with DMT crystals of varying purity atop a pellet of slag which still contains quite a bit of DMT but also lye if you skipped the ammonia wash."

My goal is as pure as I can get it.

if your goal is as "Pure" as u can get then u always want to ReX...but with MHRB i usually don't ReX ..I like the yellow crystals with the added alks..alot of Nexians actually prefer the yellow over the white/clear...really just a matter of personal preference ..with ACRB i find it mandatory to ReX tho,from my experience ...have a blast (pun intended) and keep us updated if possible how it went,good luck brother

I never re-x even with Acrb. I follow cybs hybrid tek and get lots of white fluffy crystals without a mini a/b or re-x.

I think the key is to skip the heat bath and do your naptha pulls quickly, dont let it sit in there long.

I followed nomans tek back when I first started out and had great success with mhrb. Always got pretty white finished product. No re-x necessary

There's also no such thing as an object touching another object, but for all intents and purposes it's so.

Not having a working freezer ...I have produced pretty white crystals from acacia .. and it was very weak.. i found the yellow honey dmt very potent..

I was using the fan evaporation and fat pour off method i invented and was left with a honey yellow thick paste after more drying...and white crystals looked like table salt...

I think I've come to the conclusion that white x-stals seem less potent to many people because its very fluffy and a proper sized dose will look much larger than a dose of dmt goo. I just think its easier to over do it when smoalking goo unless you're carefully weighing your doses.

The past 3 times I've used dmt I accidentally over-did it because I was smoalking waxy stuff not crystals and I don't have a proper scale at the moment so I couldn't weigh it accurately. But in the past when I had a nice scale 40mg of white crystals was more than enough.
