Castor oil experiments

[Sampei]

So ill just keep it at 30 and heat it up before using it. I used 26g and it flowed good.

It's fine even without heating, you can shoot easily 27g with 1ml syringes or use a 25g for 2/3ml barrel.

But sure If you heat it up it will be easier to draw and inject

I am currently running 35% BB on all castor blends, I sit them on my brewing hotplate at 37deg while I have my coffee, 1ml barrell tp/npp 100/100 draw 23g inject with 30g 1/2" (in fairness I tried 27g 1/2" and it flowed considerably better but 30g works)

Test D 400mg 35% BB again heat draw with 21g or 23g inject with 27g 16mm

Primo 200 35% BB again draw 23g usually and inject 27g 16mm into VG

if you are using 3ml barrels good luck, you need to be using 23-25g to inject.

Shove it.

Some say you need to spare some in order to give.

I am really not sure why I am liking this so much.

But yes.

And not even off topic.
Probably

Did you end up trying MCT / castor blends?

 

[Photon]

New year, new experiments

Test D 500mg/ml 40%BB Castor
Test Iso 400mg/ml 40%BB MCT
TPP/NPP Blend 150mg/150mg 40%BB Castor

Holding so far, will recheck in a couple of days

I'm gonna try out the Test D recipe..do you think it can hold at a higher concentration or at a lower BB%? 550 or 35%? Would it be too thick?

Isn't that a huge bump in BB% from MCT->Castor? 25%->40%?

He does high BB to thin out the castor oil

I figured..but with that much BB i was wondering if the concentration can be increased

550mg is doable even at 25% BB more like 600mg.not sure. You can try and see

This brings up a question I've been wondering about.

It would seem to me that the high BB would somewhat negate the purpose of the castor oil as a depot. Some of the testosterone would be dissolved in the BB. Higher BB content would mean more testosterone in the BB which would be absorbed quicker than the testosterone in the castor oil.

Am I off-base here? Anyone compare bloods using high BB vs lower BB?

Well, just some quick calculations shows there's not much difference between a solution with 20% BB and 35% BB. With a 150mg/wk schedule it would at most be a difference of 20mg between the two assuming Test D dissolves in equal distribution across castor oil and BB. (a big assumption)

higher BB content does reduce the depot effect to some degree. BB lowers the viscosity and increases diffusion, which can speed up how fast testosterone enters circulation. There are actual studies showing that faster-diffusing solvents like BB lead to quicker hormone absorption compared to pure oil-based depots.

The more BB you use, the more of the hormone dissolves into the faster-absorbing phase rather than staying suspended in the oil. That means less of a true “slow release” profile, especially for long esters. It's subtle at 20.... 30%, but the difference becomes more noticeable as you go higher.

higher BB = faster release = shorter duration, even if just slightly. That’s why most stay under 20% unless there’s a real solubility issue.

Bullshit xD all Bayer recipes in castor oil are 35% BB or more.

So Bayer is retarded or the reduction in absorption rate is negligible at best

35% would be so subtle....... It would be when your going higher than 45% that it reduces proportionally

I'd like to think of it like this graph

Bad graph the end should keep going up but you should get the idea.....

Bro nebido is 50% and who more then nebido needs slow release? so BB doesn't do shit to release or if it does is still just a tiny part that is not a big deal either way.

Perhaps test Undeconate has a unique feature in oil? It's quite large and lipo bound compared to other esters. Maybe this would apply better in the extreme like prop vs nebido

Maybe... what I know is that is their recipe for nebido and primo and testoviron is 35%.

Personally I don't go past 30% for anything that is not test U.

If you warm the oil 30% is enough to have it flow easily for a 25G

I'm thinking a large part of the equation is in the concentration.

If you're doing like 250mg/ml then you can probably hold most of it in the oil before adding in BB to make it less thick. But on the other hand if you're at 400+ mg/ml, then you have less oil (more raws) and the oil will probably saturate real quick and so the remainder will just end up in the BB.

I never thought of this....I'm not sure it does work like this either but it has a logic to it.

THe question is.. would you still get the half life benefit with MCT added?

This. Higher BB on higher concentration is the same BB in absolute mg amount for the same mg amount of API
