Half-Lives of Various Testosterones

Test prop
-19 hours (peak at 14 hours)

Test enanthate/cyp
-60 hours (peak at 10 hours)

Ref: Pharmacology of testosterone preparations

EDIT: this is obviously a bit different from the misguided dogma that claims test prop is 4.5 days (108 hours) and test e is 10.5 days (252 hours). this also explains how the current trend to use prop ED and enanthate EOD is actually reasonable…

So youre saying enth/cyp peaks before prop?

Source?

Perhaps for you stupid question but I’m interested, for my next cycle I want to increase the dose of test e from 500 mg to 750 mg. Question is, can I take one shot all 750 mg on monday or is it better to take it 3x250 mg per week? Also about frontloading, what is your opinion?

Depends on who you are and who you handle. For the past few cycles I would dump all of drug into my system on one day. So for example every Sunday for convenience I would…
Pin 2ml of Test 250 and 1ml of Deca 250 in 2 different syringes. Then 2-3ml of Tren 250 in another syringe and would literally drop all 9ml in one session. The convenience was awesome but I had to deal with essentially Test flu for a day or two after due to the stress of trying to process all the drugs in one time. The gains were great won’t say anything bad there.

Past 4 weeks I have been doing this…
Monday 900mg of Test
Wednesday 600mg of Tren
Friday 500mg of Deca
Sunday 900mg of Test
Tuesday 600mg of Tren

and so on and so on. This has totally taken away any test flu symptoms and the gains seem to be every bit as solid. But some say you need to space it all evenly. I just have found this works just as well just as easy and is just as convenient.
