Save your unusable raws Guaranteed.

Thanks @readalot!

I really want to try sesame oil. Seems difficult to source usp grade online. Does anyone have any advice on sourcing ?

US Pharma sells xyosted which is TE in sesame oil, single use subq injector pens with no BA BB. I think the issue is still Test E tho, with raws being back in play the easiest solution is to simply get high quality 99+% TC or TD raws.

Very true ! Im a hands on person, so I just enjoy the experimentation

For 60 USD (LOD plus KF), may be workable if you can prove LOD sensitivity is good enough (keep raws away from water, pack with desiccant, confirm with KF) and right solvent system. Nice point @mongo5165.

Looks like Jano no longer does LOD or KF.
Was trying to get it added to my order but they no longer offer it.

They can run a solvent focused GCMS but I'm not entirely sure whats the difference between that and GCMS we've been running.

Thanks for update. A residual solvents method would be great but too much business with peptides for it to make sense financially I'm sure.

could work but is too unreliable.

anyways why is the forum flooded by newbie questions everywhere? did someone bot the forum?

It's like a source board now full of people who can't be bothered to spend 5 mins using the search function..

very awful experience the last couple of weeks, theres no fun or good info here anymore. its all getting obfuscated away by bots

defiently gonna go ahead and only use the forum to look for best sources in the future

Tried to recrystalize 1 gram of tren ace. That shit is really stubborn. At first, I dissolved in some acetone like Walter did previously, but no matter how much I reduced it down, it refused to drop out. So I switched to ethyl acetate with some heptane. Still took forever to get any crystals, I let it sit in the freezer for 2 weeks before anything formed. Crystals still dont look great on the bottom. Might be from some of old raws I used to seed it but who knows. Ill try one more time with additional heptane and see how it goes.

Any idea what was your starting purity for this?

Its fairly high but no idea, raws were purchased last year and are a nice canary yellow. I just messed with 1 gram of it for shits and giggles

EA/heptane is a much better solvent/anti then acetone for TRA. Acetone can pull in water and cause oil out or lower purity. If you did not evaporate down EA to get supersaturate via thermal,concentration,or volume reduction then you will need a lot of heptane 12-15x the EA to chemically force supersaturation. Risk is higher of recrystallizing the impurities left in mother liquor back in/oiling out with heptane force crash only. Your case I would assume not enough heptane or added to quickly and over shot nucleation zone.(always add slowly until clouds, too fast overshoots). Try evaping down concentration to 50% from where you started on the EA after hot filtering. You can open air evap since no rotovap(obviously follow venting/fume protocol I would hope you are doing this already)45c 300rpm with small fan blowing over beaker. Once down to 50% cool to room temp.add room temp heptane slow and small amounts while stirring slowly or swirling until cloudy. You can seed or scratch glass and watch it go. Off to fridge then freezer.

Great info. Ill give it a whirl if this one decides to be stubborn as well

At room temp with stirring, added more heptane until cloudy. Now let's see how this goes cooling it down very slowly..

For reference, these were the original tren ace raws

Every time is different but once it clouds. I generally switch to cold heptane and add about 10% more. Should see crystals form pretty quickly then fridge for couple hours then freezer for the night generally or at least couple hours.

Ordered my ethanol today.
Gonna have some fun with my TRE raws.

Ethanol is not a good choice. It is way too polar. Ethyl acetate/heptane is best. Acetone/heptane second. IPA/heptane third. The EA/heptane is the cleanest. Ethanol will oil out. Also with TRE after filtration you most definitely want to concentrate down. Evap to 40-50%. TRE will use more heptane as well.
