test decanoate recipe

going on vacation for 3 weeks. i need a good test decanoate recipe. preferably higher dose the better maybe 300-400mg per mil.
Big pharma uses BB to get related Test undecanoate to hold at 250 mg/ml
Each single use vial contains 3 mL of 250 mg/mL testosterone undecanoate solution in a mixture of 1500 mg of benzyl benzoate and 885 mg of refined castor oil.

They also use it as a stabilizer/preservative so it may or may not be required. I'm sure you looked into it, why do pharma companies not use test E without BB instead of cyp?
E is more soluble than Cyp
maybe it has to do with E having a straight carbon chain

and Cyp having a branched chain with a ring at the end

Why do you think it’s that as opposed to the difference in stability of the hormones?
Both the steroid and ester types influence solubility
i.e. Test E holds at 250 mg/ml with no BB, but Tren E won't.
Test E holds at 250 mg ml no BB, but Test prop won't.

At the end the OP can determine solubility by trial and error
Brew Test decanoate 400 mg/ml in 1% BA 20% BB, leave it overnight to see it it holds.
Let's say he brewed 100 mL
if it doesn't hold, he adds diluting liquid (oil + 1% BA + 20% BB) to the 125 mL mark
stir, leave it overnight again and see if it holds
if it doesn't dilute to 150 ml, and so on
until it holds
then some simple math reveals the concentration.
