I think you're okay. I can't tell the difference between them when I

inject once per 7 days. You might be able to go a day or maybe 2 days

longer between shots with cyp. Other than that, I wouldn't worry

about it. The part that is different (the organic acid used for

esterification) hydrolyzes away leaving plain ole testosterone whether

you use cypionate or enanthate.

Brad,

Thanks for the info. I am just reluctant to change types in case it

affects levels in any way. Right now I am doing 200mg cypionate every

10 days.

I think the effect will be quite small. I don't usually care to refer

people to roid-type articles but this one is on point.

Brad,

Thanks! I found this section particularly interesting...

" Shorter chain esters have shorter half-lives, because of their lower

partition coefficient. Testosterone cypionate has a half-life of 8

days5, the enanthate ester has a half-life of 4 days6, and nandrolone

decanoate has a half-life of 8 days7. These figures are only

approximate. The difference between these values for cypionate and

enanthate probably includes difference attributable to different

measuring techniques. The actual difference is probably not more than

two days. "

Just heard back from my endo - according to her the two are

interchangeable.

As usual, thanks for your help,

Mark
