Compound displacements

[wsmwannabe]

I wanted to create a thread that has all of the compound displacements that I could find (not including the standard ones already found on basskiller). It was driving me crazy that I was unable to find the displacement of several compounds that I am going to brew. Then I realized it was really easy to figure these out. I simply searched for "chemical properties of xxxx" (xxxx being the compound I wanted to brew). Densities of these compound are very easy to find this way. Then to calculate the displacement, I just divided "1/density".

So far these are the 5 compounds I have. It is not hard to find more of them, but I looked these up because it was the only ones I need right now:

DHB: .905
NPP: .986
Trest A: .909
Primo E: .952
Bold cyp: .870

Please feel free to add any others to this thread, and I will add more as I brew more. But that could be a long time (years) in the future. These figures are all rounded to the nearest thousandth.

This may seem trivial to some, but those of us that are more hell bent on being exact, I believe this is very useful.

Test cyp displaces .909mL/g

but wouldn’t this also depend on compound purity? At this point I stopped paying attention to the tiny detail like that.. I just go by 1g = 1ml and that’s fine for me


interested to see other opinions

That's true, it does depend on purity, BUT if you know the displacement, that is just one more variable you are eliminating that could be causing the oil to be under/overdosed. And I think that's why overdosing by 10% is so common.

For some reason I am having a hard time putting it together in my head. Does your 1g = 1mL assumption push the solution towards overdosing or underdosing? For some reason I am thinking it is pushing towards underdosing.

Great idea

I’m likely underdosing myself, I honestly weigh what I need then add like 250-500mg extra, I usually only make in 30-40ml batches.

idk math rn

To each their own. If you are happy with how your brews are turning out and happy with the gear you are producing, then there's no need to change anything
