You'll want to run the test E one week past the deca to account for their respective active lives. throughout your cycle, .25mg/day of adex and 10mg/day of nolva plus 200mg/day of vit B6 to limit prolactin as a result of deca, a progestin.
Does B6 even work for this purpose? Are people taking B6 as Pyridoxine hydrochloride or as Pyridoxal hydrochloride? How many people know the difference and that one may work and one definitely doesn't. I've read the studies, some say there's no effect on prolactin with B6 while others say it looks to be about 10% as effective as bromocriptine. Assuming the best, will 10% produce a beneficial effect in a male bodybuilder in the real world? Color me skeptical...
As far as the original questioner, at only 300mg Deca/week, the B6 issue doesn't matter to you. In 25 years, I've never heard of someone having a prolactin problem at that low dosage.

Pyroxidine, and who claimed B6 only to be 10% as effective as bromo? It certainly does work well, if used right, and by used right, i don't mean wait until symptoms arise. If used throughout a progestin containing cycle at ~200mg/day in addition to both nolva and and AI (we're also assuming test will be in that cycle), then it works very well to prevent any progestin-induced hyperprolactinemia. the presence of elevated estrogen in the vicinity of excess prolactin is also an isue, hence nolva and an AI being beneficial.
The studies on pyroxidine and prolactin are pretty clear and pretty well-established. However, the real-world results when used right are more than convincing.
