Evaporation While Brewing

Jase · Jan 27, 2014

Hey,

I brewed NPP for the first time a few days ago and all went well, but I was wondering if anyone could tell me what exactly evaporates while heating? Is it the GSO, BB, BA or any of the Nandrolone itself?

Another thing I'm curious about... say you were intending on brewing 100ml at a concentration of 100mg/ml and 10% of the oil evaporates, but not the hormone itself, wouldn't that give a concentration of 111mg/ml instead of 100mg/ml?

Jase, can you share the recipe you used? I was told once that NPP really needed to have EO in the brew. Still trying to figure it out myself.

Jase · Jan 28, 2014

Yeah, sure mate.

10g NPP
72.5ml GSO
2% BA
18% BB

The evaporation caused a small loss in the volume of finished product, but other than that, no issues to speak of.

From what I gather, EO is only really needed when brewing at higher concentrations.

I see. So how many ml did you loose? What temp and how long did you brew it? Maybe someone else knows, but the BA is the first thing to burn off correct?

Jase · Jan 28, 2014

I wasn't very scientific about the whole thing, so I can't really give specifics. However, I'd guess somewhere around 8ml. Again just a guess.
Same goes for the temp... I mixed it in a glass beaker on top of an electric cooker for about 10-15min. My goal was to use as low a heat as possible. I started on the lowest setting before increasing it to '2'. I then decreased it once the rate of evaporation increased.

I'm not too sure about the BA burning off first to be honest, but it would make sense. Perhaps someone else can chip in?

which heat did you use?

Normally if you use higher temperature for mixing oil with solvent and powder together- the solution expands while making it to take more space.
after it cools down it takes less volume and you could think the liquid does dissapear somewhere while in fact it did not

What do you mean by "which heat?" I can't really say much more about how it was heated than what's in the post above yours.

I see what you mean buddy. If I measured everything exactly before heating though, wouldn't it be irrelevant whether it expanded and contracted?
I did see the solution evaporating from the beaker... Puzzled as to what it could be. Ohyea's reply about it being the BA makes sense, which if true, leaves me wondering about sterility issues.

I think everything was okay with my calculations, but maybe you can tell me if I made a mistake somewhere?

72.5ml GSO + 2ml BA + 18ml BB - This was based on a powder weight of .75, which at 10g, should account for 7.5ml.

I guess it must be BA, cause oil must not evaporate (only at VERY high temp) and alcohol evaporates even without heating.

The other guess is a moist NPP powder, if there was some moisture in powder you used then it will evaporate while heating, this can be checked easily, cause after your oil cools down it will not be crystal clear, little smoky, then it must be moisture.

" Ohyea's reply about it being the BA makes sense, which if true, leaves me wondering about sterility issues."
- what i was thinking but I did some checking and it seems BA evaps at 200c so I don't think that happened.
MD moist powder theory makes sense but in just 10g I can't believe that you could see that.
Lastly, did you use a syringe whatman filter? I ask because it does take around .75ml to prime that and it is lost forever...

The oil is crystal clear, so perhaps not moisture? It's a mystery to me!

If it was moisture in the powder though, it would be fair to assume that the finished product would be under-dosed, right? I'm running it at the moment so I won't be long in finding out!

Yeah, I ran it through two whatman filters, but did try to purge what I could from them. There was definitely evaporation while heating, but the amount lost was mostly a guess so I'm going to try and replicate what I did as much as possible with Test E and Mast P tomorrow. I don't have NPP here right now, but in theory I should still see similar evaporation if it wasn't the powder.

Its not the oil or the AAS that's evaporating. If anything, its the BA

Jase · Feb 10, 2014

I'd have to agree with you Beast. I had a chance to brew the Test E and Mast P... There was a slight loss in volume, only around 1ml this time though - I guess it's the BA.
