Benzyl benzoate vs ethyl oleate on inflammation markers in the blood

Ok I got it!

So progesterone injection are 1ml a day every day for 8 to 12 weeks. The patented recipes for progesterone injection using EO as the main carrier oil have 38% of EO on average. It means a woman is injected on average 2.7ML a week of EO for a duration of 8 to 12 weeks.

It's 2.25x compared to what a BB would inject if he is using 6ml a week of oils with 20% of EO as a carrier oil.

Now of course we should assume that they don't really care much maybe about CRP raise in case of progesterone injection for IVF, I guess... I mean something like: it's not great but it's worth it because the goal (fertility) is more important and it's only a temporary drawback (the inflammation).

Compared to someone blasting shit for years.

So there is that but it does put things I perspective right?

Even at 20% EO in a recipe you don't inject that much EO.

I'll still run my test, I just wanted to give you all a better idea and some datas
seems like it could be very minimal eo depending on the batch size , bigger batch less eo per dose? Right?

No the % stay always the same lol. The bigger the concentration of the oil the less ml of EO will be injected. The batch size doesn't matter if I brew 10ml of 300mg/ml test C or 1000ml the ratio stays the same

For example 300mg/ml test C has a higher volume of EO compared to 500mg/ml test D
With a recipe made of 20% EO for both oils.

The higher the % of RAWS the less oil there will be in total because the displacement from the RAWS will take more volume, and so the volume of EO injected for every ML will be lower.
 
Yeah EO is used for progesterone injection for fertility, progesterone in 100% EO. It's really loved for the smoothness of injection compared to the other carrier oil used for those injection, a bit more expensive but seems like the users really like it.

I wanted to see if anyone knew about it so we could calculate for how long they inject it and what quantity they were injecting it.

It's not something that can be compared to cycling for months years using EO but it could be interesting at least.

I'll dig more to see if I can find any info.

If one use 20% EO on a recipe on average you are injecting something like 1.2/1.5ml of EO every 6ml of gear on a 300mg average concentration of oils. If the concentration is higher the % of EO injected is less.

We are talking 6ml a week it's not a small cycle but neither the biggest. Average I would say.

So I wanted to compare it to those progesterone injection to see the difference in volume.

Anyway it will be next test. I have almost finished my mig840 assessment and it seems it doesn't raise my CRP at all (mig840) after this experiment ends I'll try EO in a 20% quantity for any recipe I use and see if it does raise my CRP after 8/10 weeks of continuous use.

It will take some time but I'll get to the bottom of this
Thanks a lot for your informations!

Is mig840 just as thin as EO?

Either way, I’ll get my CRP tested again in 2 to 3 months and see what the results show.

I'm curious as to which is a better solvent for our purposes.
According to GPT -- BB > EO > MCT > MIG840, of course real world applications may not be the same due to lack of data.
 
I think Retesto 250 from our Indian friends has a significant about of EO, if not 100%. The insert doesn't mention a carrier oil but its a 1ml amp with Test and "oily solution". No BA or BB list.

BB by a lot then EO the. Mig840 then MCT
 
hypothetically if I'm doing primo and don't want to use BB (due to intolerance) do you have any idea/guess how much EO I would need?
EO is a carrier oil with solvent properties. It's not a solvent.

Never homebrewed but looked into EO a bit. I'd say you could probably brew a lower concentration without BB using EO only.
 
How many mg of BB are we talking about injecting though?.... Not 1500-5000mg per kg of body weight.. more like 100mg total per day
Yeah I think you're on to something where the dose makes the poison. Usually we're talking lower volumes of bb (strictly used as a solubility modifier) vs EO (being used as the actual carrier oil) but there is evidence which I have not weeded out anecdotally that using EO alone as a carrier oil minus BB may actually be less inflammatory. Again simply a theory I have not tested this on myself and it doesn't appear as though we will get the same solubility using EO alone since it's not as powerful as BB as dissolving shit.

When people have high CRP or inflammatory blood markers I highly doubt it's from the EO. I would put money that it's actually the BB if it's the oil even at all could also be training diet and a whole slew of other bullshit causing inflammatory responses. No one is doing a control trial with EO. Everyone's training diet and cycles change with the wind I highly doubt anyone in here is disciplined enough to actually do a control on themselves with EO coupled with blood work to find out.

This is an excellent question because it’s all about the balance of solubility and concentration in injectable steroid solutions!


Here’s a detailed explanation:




Solubility of Steroids:


  • Benzyl Benzoate (BB) is a powerful co-solvent that helps steroids dissolve at higher concentrations in oil.
  • Ethyl Oleate (EO) is a carrier oil with some mild solvent properties, but it’s nowhere near as potent as BB.

When using 20% BB:


  • Many common steroid esters (like testosterone enanthate, cypionate, decanoate) can dissolve in concentrations up to 200–300 mg/mL (or even higher in some cases).
  • BB significantly improves solubility compared to using pure carrier oils like grapeseed or MCT.

When using 99% EO:


  • EO can dissolve moderate concentrations of steroids—often up to 200–250 mg/mL for many long esters (like enanthate, cypionate, undecanoate).
  • However, for more crystalline compounds or short esters (like propionate, acetate), EO alone might not be enough to fully dissolve them at high concentrations.



So, can you get the same concentrations using EO (99%) with no BB vs. a 20% BB recipe?
The answer is: It depends on the steroid ester.



  • For long-ester steroids(testosterone enanthate, cypionate, etc.):
    • Yes, you can often reach similar concentrations (200–250 mg/mL) with just EO, though it might require some gentle heating and stirring.
    • EO’s mild solvent power + high % of the carrier allows reasonable solubility.
  • For short-ester steroids(testosterone propionate, trenbolone acetate, etc.):
    • Probably not.
    • EO alone might not fully dissolve them at the same concentrations as a 20% BB recipe.
    • You might see cloudiness, crystals, or separation over time.
    • For these esters, BB is almost always needed to reach those higher mg/mL concentrations.



Key takeaway:


  • 20% BB: More robust for dissolving even difficult steroids (like short esters or high-concentration blends).
  • 99% EO: Works for long esters and moderate concentrations, but less reliable for short esters or very high concentrations.

If you’re working with a specific steroid, let me know! I can give you typical max solubility numbers for that compound in EO vs. 20% BB-based solutions.

EO would be the carrier oil you use it at 99% with 1% BA. As far as it's solubility with primo e. It's going to be less than using a 20% BB recipe.

Correct. BB is far more powerful and polar solvent then EO.

I guess really the original intent of this thread was to discuss what I believe is a massive over dramatization of EO's toxicity.


"Oh my God JY has 10% EO added to their test e, we're all gonna have inflammatory reactions, those oils are trash" etc
 
EO seems to increase inflammatory markers quite a lot in some people.
High inflammation -> bad, especially in the long term. molests your joints, cardiovascular system, skin (sometimes), really everything in your body.
It is slowly poisoning you, and once you really notice it you might have done some real damage.
Some people report no raise in inflammatory markers ( mainly C-reactive protein), so for some people it might be fine.

I would not make it my goal to consume as much EO as possible. Seems unhealthy. but you do you
Yeah I'm going to call BS on this there's no way people are disciplined enough to run a control on EO I just don't believe it. So many other factors can go into increased inflammatory markers. Training, diet, environment, stress, sleep.

No I don't believe that it's slowly poisoning you either this seems like more bro science being spread. In many cases it's far less toxic and inflammatory causing then even MCT oil. The very few people in the population that have an allergy to EO you can make this claim for but at that point you might as well play the lottery

I mean, you wont need to go that far as to 99%.
I'd say MIG840 + EO could be a good match, basically swapping out the BB portion for EO.

EO by itself is not as stable. Shelf life is kinda short, which makes me think twice about using it as a standalone.
 
Yea, there's only a handful of people on here that could possibly understand or have the discipline to know their own bodies' reactions to compounds with which they've done slow trial and error. They also wouldn't know their diet, training, rest, etc. well enough to factor those into any analyses. Crazy shit, right? Funny how it's the same elite group riding on EO's dick are same ones that have this esoteric knowledge and ability. So much arrogance on this board, and Spaceman/Crido lead the pack. Always have. I love how he whined about BBBG being a bully as one of his alt's over on PM, and from what I've seen, he's the biggest one around. This thread is collecting them quite well, and it has become a convenient place from which to add to my ignore list. Byeeee. Cue Sampei, the hyena.

Why are you whining about it now just because it's being discussed? If you don't like EO, then just use other carrier oils—simple as that.
