Filtering finished oils

For those that did filter oils, is it normal for the color to change?

Long story short, I had to transfer my oil to a new vial, figured why not filter it. The original vial had a yellowish (oily) color to it. After following it's much clearer now, with a very light yellow color. Is that normal?

Keep in mind .2um filtering is a standard step in making AAS, and doesn't removed active ingredient.

What kind compound was it?
 

I used that to filter the test e, it was posted on the forum, can't remember where.

Attached is the color difference, my description may be over exaggerated. Not my intention but I'll let you see it for yourself to come up with a conclusion

Your test has crashed and crystallized, collecting on the side of the vial.

I'd put the oil back in, warm it on a coffee burner or put in over at 175f for 30 mins.

Shake it well,

Allow to cool for 3 mins, then refilter the warm oil back into the new vial, using the same filter if possible.

Not that I'm questioning your expertise, but I think it's the picture. In person it looks much better.

Here's a picture without the sticker as mentioned to show the difference. Should I still filter moving forward? Is the color difference normal?

a SAFE bet is to Always re-filter, IMHO,,

There shouldn't be any color difference. all of the oil and aas should pass through the filter, unless it's crashed (crystallized) in which case the filter would block the aas(which imparts the yellowish tone), and only the oil would pass.

That said, maybe the picture was deceptive, That coating sure looked like crashed gear. You don't see any sign of solids in the vial? Flip it upside down and check the bottom. If there's nothing at all there, I have no explanation for the color difference.

Nothing at all, it's clean. I'll ask the supplier and see what their response is. I'm doing blood work in 2 weeks, for now I'm definitely feeling a difference in performance.

I'll also heat up as you suggested and see if there's a difference in color before and after filtering.

Yeah, bottom line is there should be no difference color wise before and after filtering it. All oil and dissolved aas will pass a .22um filter.

Unless other adulterants being removed by 0.2 um pass. These would be particulates exerting color or color bodies adsorbed on filtration media.

I can't tell from the pics.

*Should* not be a color change if it's proper Test E. After all, it's supposed to be filter sterilized leaving nothing to be removed by another round of filtration.

All the other possibilities point to something really wrong here,
 
guys wtf there is many time a color difference and it can be because of not so much oil in one vial vs other vial being almost full, you know lights refraction bla bla bla.

Sometime no offense you really go on some crazy nonsense rant, same with some oils freshly brewed has a color and then it changes a little bit with time.

there is no fucking mistery here damn

Break out the Hunter Colorimeter lol.

To your point could be optical artifact.

Hey I was just pointing out this looks like crashed gear sticking to the vial. Doesn't this look like it to you? I've seen similar a number of times.

Some dyes don't pass through a 0.2 um filter. That is all. No controversy. Synthetic dye in that oil? Probably not. Would hope not. Could also be naturally occurring color bodies in the oil which is function of temperature history, oxidation, AAS quality.

Usually oil crash from bottom to top, never seen the opposite.

I bet it's just a bad picture

I agree with you, in person it looks much better. I'm not going to downplay the issue if I think there's a problem. I'm injecting it into my own body in the the.

The yellow tint is apparently from grapeseed oil. Still no confirmation on the color change. If anything I'll get it tested at Jano. This evening I plan to reheat a new vial and check it out.
