test prop half life and shelf life

[jef]

What is the actual half life of test prop? I ran a cylce for about 6 months a couple of years ago and 3 of those months were everyday hits of test prop....I ran it e.d. to keep blood level stable but now I've read it's half life to be 4 days, 2-3 days etc and nothing is conclusive. I was going to run some test cyp for the next 6 months but don't want to have to order more....at the same time with what i have I do not want to be looking at shots everyday. If it is 3-4 days that would be much easier. Any recommendations?

Also; what is the shelf life of powder and gear already made if it's been in a cool, dry place?

Ran a search and looked through pages but couldn't find anything.

Thanks guy
