Hmmm,

I was a little amazed at the caber half life , I was under the assumption , that it was a lot shorter ,  like 3 days meaning I may have been over dosing my caber . No wonder im always ready for the beach. Lol the wind can blow and im ready.

With Cypionate and Enanthate Half life's,Cypionate is around 7 days and Enanthate is around 5 days....Prop is more than 2 days I would say leaning more towards 3.Bloodwork would agree with these days.... I really with Cyp's half-life was 12 days LoL would make TrT cruising a breeze....+1 Good Post

Dont trip... Yeah,  there is a lot of different opinions on this if you google it you will see that your opinion as well as the half life I posted are all over the board.. The reason I put the one that i put down was strictly based on my own bloods. After almost a month of lowering my dose from a gram a week to 200 a week my bloods were still 7400... It kinda freaked me out a little bit so i had it redone with similar results... I think everyones body is different so its really hard to put an exact number... These are simply guidelines to help out as much as possible.

Thanks for your input brother.. Everyones opinion a valuable and worth listening to...

and double checking! :)

Too funny, I was looking to check the half life on Anavar and I found my own post from a while back! Forgot about this one!

I see so many different half lives posted for certain esters lately it’s confusing. I’ll name a few but there are too many to list in a comment... Propionate-some times listed as 2,3, or 4.5? Cypionate-as 8, or 10.5, or 12??? Enanthate- 7, 8, or 10 and even this one lists Sustanon- at 14?? Which is possibly the half life of decanoate or is it??

Not my my intention to step on anyone’s toes and I’m clearly confused but information is getting sooo watered down if you are not obsessive in verifying source information you are hardly informed.
