Home brew came out underdosed, How?

[112yagosmi]

So I bought 96% purity TC raws from a well known vendor here. I brewed them in MCT at 2/20 with 10% OD of 250mg/ml. I filtered with a whatman syringe filter and sent a sample to jano. It came back as 188mg/ml

I don’t know how this happened.

The scale I used was brand new and accurate according to the calibration weights. I also put a 10g bag of tren on the scale and it weighed 10.3g.

The raws tested at 96% purity by another member just months before I got my raws. Reading back the raws were constantly tested as 96-98% within the last couple of years.

The beaker I used was from medlabsupply and it was accurately calibrated. I measured the ba/bb with a BD syringe. My math was correct I’m 110% sure of that.


I used mild heat and a magnetic stirrer only long enough for it to dissolve. Maybe 15min.

The only thing I can think is I didn’t use the magnetic stirrer and heat long enough and some raws got caught in my syringe filter and lowered my mg/ml of finished oil. How long do you guys stir for?

Anything else you can think of that possibiy went wrong? I felt like I did enough research and bought name brand products so it should have come out correct.

I also never let the brew get above 100F and filtered it while it was still warm (by hand not by cawk gun)

I agree on the filter as a likely culprit after such a short dissolving time. I like to let my mixture stir for 45 mins while I setup and prepare for filtering and bottling

How high do you let the heat get for test c?

I dont think it was the Filter , Thats Not possible .
I think your raw was shit.
Who was the raw seller ?

 

[theotherguy]

Did you have any spills? Was there any raws left inside the beaker, unmixed? like maybe it got stuck on the side and never made its way down into the oil? There's a million variables that can cause that lower concentration. Best case scenario, you should've been close to 211 mg/mL if you dosed @ 220 and it was 96% pure, so that is a fairly significant drop in concentration.

O shit, I just re-read it, you brewed at 275, not 220. Yea that sounds like some BS that you got such a low reading. I have to assume this isn't your first brew?

EDIT: 15 mins does seem like an awfully short amount of mixing time. Maybe you filtered out some of the hormone? I'm not really sure

 

[MrLoop]

there are only two possibilities. either you are a zero in mathematics or your raw material is garbage

No spills.

I’ve brewed tren and npp previously but I never had them tested with jano.

How high do you let the heat get for test c?

I think around 65-80C? My method isn't an exact science, honestly I usually go by touch. If it's too hot to touch I remove the beaker from the hot plate, turn the temp down a touch, then put it back on after about 5 mins. I know that's not terribly helpful or scientific.

I also keep the heat on but turned down to about 50C, and turn off the stirring when I start filtering and filling the the first vial. So depending on size of batch (50-100ml) I will still have 40-90ml remaining warm. Not sure if it matters but I doubt it hurts.

Test Cyp raws takes usually more time to dissolve in my experience.
I use low heat, and magnetically stir for about an hour or so, until the oil is completely clear.

So there is a possibility that some undissolved raw got stuck in the filter,

I don't think that your raw was that much underdosed, I think we have newer seen a test c raw with less than 90% purity.

 

[MrLoop]

if raw material does not dissolve , this is visible in the solution . there would be some raw material in the filter and that would also be visible. once a raw material has dissolved within the solution, it does not return to the starting material.

 

[theotherguy]

No spills.

I’ve brewed tren and npp previously but I never had them tested with jano.

How are you storing the raws? How long did you own them before brewing? The raws may have lost some purity, but I think it would lose that much.

I didn’t visibly see any raw in the semi finished oil before I filtered it

I had the raws 3-4mo before brewing. I stored them in my closet in a vacuum sealed bag. I keep it very cold in my house. I did order them during summer though…

 

[Evom1]

The only two things here that make sense would be

The raws were not as pure as you thought they were

Your calculations were off

 

[H&M]

Something strange goin on here....

You also said you went off the test results that someone posted 6 months prior. There's a good chance you got a different batch that wasn't as pure as the one tested.

They have had consistent testing of this sources test c for nearly a decade now and it’s never been under 96%. I don’t see a percentage drop of that significance in purity is possible. I don’t think I’ve ever in my life seen test c that impure from ANY source

 

[theotherguy]

I just don’t see purity being the only issue here. Brewing at 275 mg/mL and only getting 188 mg/mL would mean it’s 68% pure. Not saying that’s impossible, but I don’t think I’ve seen test C under 94% on here. It’s gotta be a combination of factors

Honestly the only thing I can think is the beaker from med lab supply was inaccurate. That’s the only thing that makes sense. I’m going to buy another beaker from a different science supply company and see if they are identical in the amount of fluid they hold at the 100ml mark. Because the hormone was fully dissolved and I kept it stirring as I was filtering. I know I didn’t stir it long, But it’s the only conclusion I can come up with because I’m good at math.
