Save your unusable raws Guaranteed.

As said by others surface solvents are easy to remove via vacuum and mild heat. But solvent/impurities can and will get trapped in the lattice and amorphous regions if crystals rapid form. This is why we are recrystallizing in the first place. Its the shit that gets trapped behind from yield being more important than quality. Just did recryst on some of the shit TC from AASraw I just got. Off to Jano Monday with before and after samples. MP is good at 101.2 initial and 102 clear. Nice sharp MP. Happy with the result on it. Just ethanol as solvent and carbon wash/filter through celite and slow cool from 60c. Seeded at 40c. MP video starts at 101c 1c/min rate. Out of the bag MP was 90c initial and 100c clear. So both depressed and extended. Powder looked fairly white(light beige)but was yellow as piss once in BB, would not go into dissolution. I ran it up to 250mg/ml in straight BB and up to 150c.

Were you able to figure out where the yellowing came from?

do you still have your tg?

i do been nuked a few times but each time some hater decides to nuke i grow 10x the size so i consider it a celebration for growth lol last time i was nuked i had 300 then i got 900 i expect 1500 soon

pee

i sure love pee in my raws its actually anti bacterial i heard

Some non soluble garbage. Maybe oxidation? Crystals all dropped and came out clean. Once filter dried out it looked like dust bunnies on the filter. All the color stayed in mother liquor. Crystals washed. Pretty clean.

Can see color difference's, boat is the Recryst

Some TD just done.

Some TD just done.

What solvent did you use for TD?

 

[Motojager]

What solvent did you use for TD?

Ethanol to reflux, hot filter, rotovap to concentrate, slow controlled cool from 60c to 18c (.25c/min 3hrs) then fridge overnight.

how difficult is this to do on a large scale for kilos

 

[goo]

what is the current tele? just read through the entire thread excited to try this for myself since I just got 92-93 percent purity test prop raws

i do been nuked a few times but each time some hater decides to nuke i grow 10x the size so i consider it a celebration for growth lol last time i was nuked i had 300 then i got 900 i expect 1500 soon

how difficult is this to do on a large scale for kilos

by the process itself its already done in LARGE vats at the synthesis labs at least officially. when i made this thread i was reading how industrial purification is done and i simply scaled it down to home use. if you have the time and the lots of energy then yeah it should be pretty easy to process kilos and kilos at a time assuming you got enough solvents....however its better to do it small batches at time instead if you really want to make sure you get the best you can. getting to 97 to 98% pure is the easy part.

getting to 99% and 99,9999% ...yeah thats a vast vast vast effort level there. if you got kilos better to split your batch into 500 to 300 Grams at one time and process it untill you get something clean. then repeat. going all at once will give large error and harder to control

i processed like 500 grams of eq however that was a whole other ball game had to do vacuum distill and liquid to liquid extraction

if you got some AAS raws test just process your stuff in small batches.

Hey folks, I just pulled off something cool: un-baking the cake and recovering raw testosterone enanthate from some old homebrew in GSO. With oxidation creeping in over time, I figured why not extract the goods? It was a bit of a pain at first, but once I dialed it in, the process was straightforward. Here’s the step-by-step in case anyone wants to salvage sketchy gear (this should work for MCT oil too).

Step 1: Initial Setup & BA Strip
Chill everything in an ice bath.
Add 30 mL n-heptane to the GSO/test mix—it emulsifies beautifully.
Add 10 mL water to pull out the benzyl alcohol (BA).
Chill again; the water + BA layer sinks, leaving heptane + GSO + test + BB on top.
Syringe out the bottom aqueous layer and discard. Repeat once more.

Step 2: Polar Extraction (Test + BB to Ethanol)
Still cold, transfer the heptane mix to a separatory funnel.
Add a 70/30 ethanol/water blend (start with ~40 mL).
Gently swish (no shaking!) ~20 times.
Pop it in the freezer for 10 min—layers separate like magic:
Bottom: ethanol/water + test + BB
Top: heptane + GSO
Drain the bottom ethanol layer into a beaker; save the oil layer in another.
Return the oil layer to the funnel, add fresh 40 mL ethanol/water, and repeat 3× total to grab every last bit of test. Separation is lightning-fast in the freezer.

Step 3: Dry the Ethanol Extracts
Combine all ethanol pulls.
Add anhydrous magnesium sulfate on a stir plate to soak up the water.
Filter out the MgSO₄.
Step 4: Strip the BB (the tricky part)
BB is stubborn—even under deep vacuum it needs heat.
I set a small electric hot plate under my vacuum chamber; ~1 hour did the trick.
Tip: You might be able to recrystallize with BB present, but I haven’t tested it.

Step 5: Crystallize the Goods
Add just enough ethanol to cover the remaining test gel in the dish.
Freeze overnight—BAM, crystals!

Clean, sparkly test enanthate ready for a fresh brew. Hope this helps anyone sitting on questionable vials!

Is there a way to do this without heptane?
