TweetYes, I have that exact copy. However, it's old and out-moded method of treatment. Most endocrinologists I know prefer weekly injections of 50-100mg now, as it keeps blood levels more stable. You have to realize, docs who wrote the PDR don't know much about the actual half-life, they don't even have it listed However, those 400mg shots once a month cause bad spikes and valleys, which is why I say that the half-life cannot be very long, but who knows, someone very very smart will come along someday and enlighten us both Long as I get bigger, who really cares anyway!

No, it's not, look on anabolic review, or try the PDR... they do tend to know about the medications they invented

which one is it? i thought you just said the PDR was right

TweetThe half life of EQ is 17-21 days.............

Half-life of cypionate is 12 days, Ethanate is 14 days. I really dont know where you got your figures. HRT is done every 2 weeks, the doctors must know something right? Bodybuilders take shots more often, to keep blood levels more stable. Androgel is usually a better method for HRT, becuase blood levels are more stable. So if you say an ester like Ethanate has a 5 day half-life, then whats prop, like 4 hours?

TweetYou are wrong again there, cyp is longer than enth, not the other way around. Cyp is the longer and heavier ester, and slightly slower release rate. Prop is about 2 days, not 4hrs, phenyl-prop about 2.5-3days. And that's WHY docs use androgel instead of shots more often, b/c patiens don't like weekly shots, but otherwise their blood levels dip too much and they get side effects. 100mg/week is the best replacement, much better than 200mg/e2week. But lets put this to rest, no one seems to know for sure, we've both got reliable sources that disagree.

TweetI thought EQ lasted longer then 7 days?
