Transferring oils for long term storage

This is a ridiculously embarrassing question, and I'm posting here because it pertains to my re-vialing efforts, but also to limit visibility lol I know the answer, I just need reassurance

If I take one of my 30ml ALK Flurotec vials and fill it with;

15ml masteron enanthate 200mg/ml
15ml masteron propionate 100mg/ml

Then I'd be left with a masteron blend with 150mg/ml total concentration made up of;
Masteron enanthate 100mg/ml
Masteron propionate 50mg/ml

Am I forgetting something? Are there any issues with this, perhaps differing BB concentrations, that could lead to crashing or some other issues possibly? I also plan to do this with some Tren Ace 100mg and Tren E 200mg, and maybe some nandrolone decanoate and nandrolone phenylpropionate. Anything I need to be aware of? Would mixing GSO with MCT be an issue? I do it short term for the purpose of immediate injection, wasn't sure if sharing a vial long term might be a problem. I'm new to this, but that has to be painfully obvious with these kinds of questions lol
No problem at all on any fronts
 
I typically do every other day injections, and while I like prop a lot, I think a little enanthate can help with slightly more stable blood levels, while also allowing for a bit less oil volume. I expect nearly zero perceivable difference, but since I am re-vialing anyway, I figured why not make some silly crap while I'm at. I've got so much mast, a few 30ml vials of the blend isn't going to make much of a dent in my separate esters, and it's not like it's useless literally, just arguably useless practically.

ahh the "experimental medicine " , i get it , well im interested in just what others say , you don't really hear alot about mixing esters

Sustanon is one of my faves; also used for TRT in the UK
 
Another day of transferring oils. Today I moved my Tren Ace from Stan to Flurotec ALK vials. I transfered six of the vials into two 30ml vials, and the rest went into 10ml vials.

3 into 1 fits pretty well. I sucked out 60cc of air from these (20cc from the 10ml's) after filling them, so there's some vacuum/reduced oxygen in there. The two 30ml vials are already in the freezer. The rest will likely get frozen as well as I have too much Tren as it is.

These ALK vials are so perfect in volume for direct transfer from Stan's generously filled vials. Look at that perfect, tiny bit of dead space:

I have been using a 16 gauge to withdraw the oil from the old vial as the stopper is going to thrown out anyhow, and it makes withdrawal of the contents very fast. I would then switch to a 19 gauge for injecting the contents into the new vial to balance speed and stopper preservation. I decided to try out an 18 to help speed up the process, and here is an example of the difference in the stopper afterwards. These are the ALK Flurotec stoppers, 19g on the left, 18g on the right. 22g vent for both.

I'm confident the seal is not compromised, and I use the adhesive foil vial seals on all vials, but my OCD made me stick with the 19g. I just don't like the aesthetics of that stopper scar. I was genuinely surprised there was such a big difference. Both vials were penetrated with new needles, at ~45° angle.

Here's everything mostly done, save for the label transferring and vial seal application, which went on right after, but I forgot to take a picture.

Still got a ways to go, but it feels good to make progress in this project.
 
Got any 21g needles?
I personally use 22g for transferring.

I've got 16, 18, 19, 20, 22, 23....etc... so no, but I'm always down for another order from lab supply companies. I don't know how much patience I have for anything smaller than 20. I use 23 to withdraw all my oils, so these are single time piercings. Dammit, now I have a reason to make this whole process go even slower lol

That’s a beautiful sight is there such a thing as too much tren? haha I don’t have enough

Try 22g, it's pretty quick.
Imagine those thumb gainz!!
Remember to train both thumbs.
 
21G to inject the oil is super quick, don't be impatient.

You don't need anything bigger than that to inject the oil into sterile vials. To draw yeah use a 16g fuck It.

Draw with 10ml syringes, easier to push and super quick.

If I can filter a vial in 20 seconds with a .22um 21G you can definitely just inject faster. You don't have to go through a filter

It's interesting that the 21g had less coring at a 45° angle when compared to 90°, while the 18g had more coring at a 45° angle vs 90°

Now I'm regretting all the work I did because I used a 19g needle. I have enough ALK vials to redo them, but do I have the sanity? Also, would I need to filter at this point since small rubber particles are the concern? I'm driving myself nuts now.
OCD is one heck of an affliction. I'm about to be examining the vials with a magnifying lens for stopper particulate matter.

Wait... I think I see something in one!

No seriously, someone tell me "nah, I'm sure they're fine, just use 21g from now on" or tell me "you better re-re-vial and filter that rubber laden crap you just created" so I know WTH I'm supposed to do now

Is freezing the way to go for long term storage of oils??

For very very long term storage, it will definitely be a way to all slow oxidation of the oil to a snails pace crawl, all but eliminating that as a concern. It will, in general, slow all chemical processes that would lead to rancidity and potency degradation. I think 20+ years is absolutely no problem, with more being a likely possibility, if everything is done correctly and seals hold their integrity.

What about worry of condensation forming?
