Information about the yellow NPP

[BigL89]

Hey Friends,
I am startet homebrewing at the Moment.
Unfortunally as a First RAW I got some of the Bad Smelling yellow NPP that was discussed a Lot in this Forum.
After solving in BB and mix up with BA and MCT, I get a dark yellow cloudy „Solution“ with pretty much Sediment in it.

After Filtering with 22um I get a clear light yellow Solution. But now I have no idea about the concentration. I made 100mg/ml with 10% overdosing.
But with all that Sediment in the Solution I think the raw is less Then 90%…
I searching a Lot, but could Not find anyone who did a test on that yellowish NPP raw…
Did Anybody Test or Even Use that stuff?
I think its all the Same Batch from Same Factory, only different Chinese Suppliers who Sell that…

And was another test at around 91%

Okay Thanks a Lot!
And has Anybody made personal Experience about PIP and Health issues?

Its really hard for me to Self use a steroid knowing, that it has the wrong Color and has had a bunch of Sediment shit in it

You have GCMS done on that batch if that helps. PIP none reported

The new batch is clear and 95 percent.. I'd toss that one out and get the new batch

that impurity is often result of irreversible oxidation, basically these raws was improperly stored. there is a few things you can do to get rid of this impurity but you will lose product and theres always a chance the color is polymorphic and has fundamentally changed the steroid ring itself. Depending on how yellow and dark this is really depends on how far along it is on this path. also simple recrystallization will struggle to remove this as its solubility is likley very very very similar to the target api, in which cause you will have to turn to a liquid to liquid extraction and some bleaching powder (mostly activated carbon) and a process to control heat and moisture

tldr id trash it or be ok with the color. your target api is there. you can over dose it and just work with what ya have. but you are also accepting you will be injecting that impurity with unknown consequences.......your choice
