I do my best not to recommend anything.
I can only tell you what I am doing now and what I am going to try:
Currently, I use my Test cyp 0.6ml on Sundays. My last serum T on this was 831; and I am happy with that. I have been doing that same dose since November 2017.
I want to change to Test U (250mg/ml) 1.8ml every other Sunday. The math for the conversion is all over the place depending on what you read; so I am going with a rough mean of what I have gathered to keep my serum T similar to what it has been.
It will be a pretty good while before I can get reliable blood work on this because I am currently on a gaining cycle and I am injecting all kinds of stuff to test my products before I release them.
I am very glad that I ordered big for most things and won't have to do so many test injections for a while because all these test doses have me chasing my tail with AI dosing.
This week I am injecting Test-U, DHB and primo. I am dreading the DHB because I am a major PIP sissy.
Just a heads up, I made Test U in 50/50 GSO/MCT and based off bloodwork it has no where NEAR a 30 or even 20 day half life. I’d guess maybe 10. It really needs to be in castor oil if you only want to pin 2x a month.
