Test E Homebrew Question - Is 2% BB Sufficient for Stability?

[AlhambraGB]

Planning my first homebrew of Test Enanthate and want to verify solvent ratios. From my research, Test E typically requires:
- 1-2% BA (planning 1%)
- 15-20% BB (most guides suggest 18-20%)

However, I’ve seen a few sources claim Test E can hold at just 2% BB when using MCT oil, even at higher concentrations (250-300mg/mL).

For experienced brewers:
1. Has anyone successfully run Test E long-term with only 2% BB? Any crashing issues?
2. Does carrier oil (MCT vs. GSO) significantly impact minimum BB requirements?
3. Any other tips for first-time Test E brew? (Sterilization, filtering, etc.)

I’ll be brewing small test batches first, but want to avoid wasted raws. Appreciate any hard-earned wisdom.

You can brew Test E 200/ml in mct without BB only 1-2% BA.
If you can tolerate BB, I see no reason to avoid it.

Personally never brewed E. All Ive found is that since it has such a low melting point is that solvents are rarely needed. MCT apparently acts as a mild solvent also. So, just brew a small amount, filter and vial, and do what I do when trying a new recipe or raw batch, chuck a vial in the fridge for a week and see what happens. If it holds then you know that no matter what happens you won’t get crashed gear (unless you live in Alaska or some other God forsaken place).
Not quite sure about your aversion to BB though…

Lots of discussion on this kind of thing in that thread. No offense, but why Test E? There's so very many instances of it causing hurendous pip. I hate to see you spend a bunch of $ on it just to discover this for yourself. When it's nice and clean, yes, you get a little bit more bang for your buck, but it's a gamble. If it's bad, you'll see, you'll end up throwing it out

Get yourself some Test C, or do what the big boys are doin and go Test D--you can brew this up to around 500mg/ml.

Edit: Look at this thread here Fever, lumps, aches etc. after injection

See? Test E= Ouch!

Test E in my experience has no more PIP than any other Test esters, if it does then you need to check your source.

Yes, 2% BA is sufficient for Test E. Test E is actually soluble in carrier oil alone but in my opinion should be avoided for sterilization purposes. The small amount of BA should help keep it sterile and safe for use.

Test E is notorious for being tainted and it's postulated that this can also happen after the raws age.

If you get a bad batch, you'll see. The pip is fuckin insane bro. It's not a source problem, it's a manufacturer problem. It's all over the place too. Read through some of that last link I sent. Read through the dozens upon dozens of threads in the forum here. Don't just take my word for it.

I will look into sourcing test D instead, I’m glad I only bought 50 grams. I never had a problem with test E either but don’t want to risk it. Did you send your raws to Jano ?

No, but a friend of mine was avid about that kind of thing, so he had them tested all the time. Even though the pip is outrageous, it still works. It's just pip so bad, not a normal soar feeling that you get from some compounds, I mean this shit HURTS man. It takes hours and hours for it to set in, but once it does, it just sucks.

I'd say, brew some of what you have up. There's no gurantee it's good or bad/tainted. Pin it once, and if it hurts like hell the next day, toss it. If you're good, then you're all good to go--might as well brew it all up.

Test is so cheap, it's not like buying Trest or something. Don't feel bad either if it's bad, I blew $200 on it once, it was all bad. Easy come, easy go

For the record I have been doing this for a long long time and have been through many sources and have never gotten any test e that had pip after brewing up.

I took a shot of a new batch of test e I brewed up from a new source on here since mine went down with the stuff going on in China and there is no pip but a raw powder sample and an oil sample of brewed product was also sent to Jano for testing.

I got mine from a Chinese source fairly new so I’m hoping there is no pip with this batch.

You're lucky, there's posts all over this forum of people who experienced this issue, both from raws and from finished product. Take a look around. I'll see if I can provide a link or 2 as an example.

 

[AlhambraGB]

Yeah I’ve read a couple of post about recent test E raws giving people flu like symptoms! From new batch raws

Post in thread 'Melted raws'

Jun 1, 2025

I will tell you why I believe that.. because over many many years.. I can't give you an exact amount.. I bought test e for my own TRT.. from 2009 till maybe 3 years ago when I switched to test C.. I generally had a habit of buying a couple hundred grams at most and brewing it when I got it. Then I would put all the vials in my safe and use them till they were gone, but sometimes I wouldn't brew all of it I would keep some of the raw material and leave it in the safe, And then try to brew it later.. And every time, that second batch I brewed from the same raws would f****** up bad every...

Thread 'Fever, lumps, aches etc. after injection'

May 8, 2025

My client has reported that he feels sick after every injection of my gear. He says he gets fever, insane body aches and hard painful lumps at injection site. These symptoms last up to 2 days after every injections.

I have over 600 clients and haven't had such feedback in 3 years.

I think he is taking Test E and Primo, around 1g of Test E and 1g of Primo per week as I was told.


My recipes are:
Active compund
20% BB
2% BA
Rest MCT oil

Did anyone else had similar experience?

Thread 'Test E pip and issues'

Apr 17, 2025

Hi all! Been homebrewing my own stuff for some time and never until now had any issues especially with Test E but now I am experiencing mild pip in injection site and a mild fever for a couple of hours after injection that eventually goes away but it is pretty annoying and I am thinking where did things go wrong. Raw powder is tested and sitting at 95% purity, may be not best quality and purest but already brewed from same batch at 200mg/ml without any problem, now that I have tried 250mg/ml the above said occured.

Everything is sterilized prior to brew, filter is 0.22 sterile, working...

in the big picture with multiple users. Test E has more inflammation than test C. period

Have these same people that were making test enan switched over to test cyp from the same supplier and not had PIP with the same sources test cyp?

I’d be curious to know. I’m not saying people aren’t getting bad raws because I’m sure they are out there but testosterone any eater is very cheap to make over there and if very rarely faked.

Myself that has just never been the case and there are so many variables that could have cause these test enan users to end up with PIP. They could be off on their BA percentage, could have used the wrong type filter and had the filter break down due to the BA and/or BB which will happen if you don’t select the correct filter membrane and cause atrocious PIP.

Most of the stuff comes out of the same pile of gear... All 96-98%

I have made test e for myself. Injected it and got a knot.

Gave it to my friend(same vial). He doesn't have the issue at all.

BA shouldn't play as much of a role a we think. Sustanon has 10% BA and no BB.

I only utilize ptfe which can take the harsher solvents ass well.

It's the majority of UGL raws.

Overall, there are more reported problems with test E than C.

For me, same supplier. Same supplier for years.

 

[AlhambraGB]

What’s everyone’s process for sterilizing vials ? Or do just transfer into a big sterilized 50 ml vial ?

Please show me a case where 10%BA was used in a Sustanon mix. I’m not buying that at all, that shit would be intolerable to a fucking horse!

I’m calling BS on that one.

The percentage of BA most definitely plays a role in PIP. Even a small bump from 2%-5% BA causes a noticeable difference in PIP. Now BB is a different story, you can use 15%-20% and not notice much if any of a difference.
