anyone ever make NPP before?

[Stonecold54]

I would have put this in the chemistry sec...but I wanted more people to see it...my NPP is just cloudy...I made it at 150mg/ml with 15%BB and 3%BA...I heated it up and it never homogenized...then it actually fell out of solution last night...today I have been slowly adding small amounts of BA and BB to it and heating it to see if it holds...I can't believe it would take this much solvent to suspend it even at 150mg/ml which isn't that high. Most stuff will suspend easy with 1%BA and 15%BB.

That is strange. I would have expected it to be a little more soluble than that. I assume you are sure of your powder source.

I have never worked with any phenylprop esters so I can't be of much help. Try diluting it down to 100 mg/mL with 3% BA, 15% BB in oil solution and then heating it in the oven for 10 minutes or so at 250.

npp is a bitch bro. your not going to get 150mg/ml. I would try for 75 to 100mg and add some PG if that doesn't work and raise the BA to 5% (if you can tolarate it). Ethyl Oleate might be a better option here as well.

I have had people claim 200mg/ml and no problems but I doubt it much (I thik they actually had nand cyp, much easier and better to use anyways if you can find it.)

shit okay guys thanks...I will just scratch this batch and get some more. thats weird because I made TPP before and it was easy and smooth.

I don't think you can do NPP at higher than 100mg/mL easily.

Yeah I diluted it down to 100mg/ml but it still ain't clear..oh well...I will try to add some PG and see what happens.

you could try adding some of Mr.Ts supersolvent. Not sure though, I have never made NPP, but plan on it.
