brandon is quite right for most part. if your already 5 weeks in your test c cycle and you havn't started your deca then I would wait till the next cycle to add the deca, unless you want to run your cycle for 17weeks or so. deca takes a long time to kick in.
The only thing that I disagree with, (and that's just up till recently) is that nolva doesn't help with progesterone gyno. I'll explain, I've heard from people that nolva helped them, I didn't believe them because of all the studies I had read. There was one important thing that I didn't know, from the last study that I've read I learned a big difference.
See most of the researches are made on women with breast cancer. we dont' have breast cancer. here is a quote from the study.
"The observation that PR status is
different in response to tamoxifen depending on the
normal and tumour breast tissue is highly important. In
normal epithelial breast tissue, tamoxifen downregulates
PR, while in breast cancer tissue it upregulates the
receptor, which indicates that tamoxifen plays a greater
agonistic effect in tumour tissue than in normal tissue."
