NPP 200

[Gmanzx11]

Any good tried and true recipes? I’m new to brewing, I’ve got the Test C down. Used up the last NPP 200 that had from a used to be source here. I jumped right in to trying it at 200. I’ve searched all over for recipes and this is the one I tried:
NPP
200mg /mL - 20ml
NPP powder - 4 Grams
100% EO - 12.6mL
2%BA - 0.4mL
20%BB - 4mL
It crashed hard after about 4 hrs!! Really like to get this high concentration mastered. Less pinning!! Any help is appreciated.

Add 4ml gcoil. Plus I use 23% to 25% in all my non-19's

Trying to stay away from gauiacol. The wife hates the smell!!

What can I do with this batch? Add more bb?or just Heat it and shoot it before it crashes? Probably crash in my ass and knot me up for a week!!

I’m fairly certain you can double the volume with MCT and equivalent 2/20 BA and BB and it will hold at 100mg. If 200mg doesn’t hold with 100% EO, I doubt you’ll pull it off without guaiacol. Maybe with Mig840.

You’re assuming the Npp 200 was actually 200mg.

I’m going to add more bb and see what happens. I still would like a good solid 200 recipe

I hate to say it to you but the best 200mg npp recipe is to make it at 100mg/ml and pin 2ml for 200mg
Because I doubt you will get it to hold without guaiacol and even then it's a shot in the dark

Ok I heated up and un crashed the 200. Pinned .10ml in thigh to test pip. That was Sunday. It had some bite. Still feel it a little today. Wednesday I added 2ml BB and 10ml of MCT oil. Reheated and sterilized. Should be 150 a ml now right? It hasn’t crashed. I just pinned .5ml in other thigh. hopefully I can walk in the morning!! Thanks for all your input!!

200 is hard , but it will hold with gcoil . I know u said no gcoil so i would stay at 150 .
