Thread: 400 mg/mL Test Cyp?

Anyone have any luck making 400 mg/mL test cyp? If so, what recipe did you use?

Test-c no I don't think its possible its hard enough to get it to hold at 250mg/ml
Test-e yes it will hold easily at 2%ba and 20% bb

Damn, 20 percent bb gotta have some bite. Strange Test Cyp won't hold, its only 1 carbon heavier.

Made 400mg/ml test cyp in pure ethyl oleate with 1% benzyl alcohol. Has been holding for over a week at 63 degrees f. I have not injected any yet, but I do well with ethyl oleate. Will update after injecting.

Is there an easy way to predict solubilities? I know for oral suspensions you match your AAS molecular weight to the PEG weight, but there does not seem to be a correlation like that with oil injectables. Any thoughts?

Looking in the recipe section, it looks like Test-C and the rest are all done with sesame seed oil. I use MCT oil, would I use the same volume of MCT oil, BA & BB as listed for the recipe with sesame seed oil?

If not, what would be a good recipe using the MCT oil, ect... for 20 mL of Test C at 250 or even 200?

Thanks in advance and sorry if I have this question posted in the wrong section.

bb at 20% i have no bite issues with using a higher bb is way better then eo or different solvents

There is a sponsor on this board that offers Test-C at 400mg/ml. According to the above responses,
it would seem very unlikely that the label claim is being met.

I agree with this completely. I've brewed test-e 300mg/ml with 10% bb and 20% bb and couldn't tell a difference when injecting
