I'm about 4 or 5 weeks out from finishing up my cycle. I plan on running an assortment of items in PCT to help retain and increase gains as well. The list:
6) IGF-1 LR3
7) CJC-1295 (DAC)
and the last item of special interest...
Two things we'll learn in this 6 week PCT:
1) Comprehensive Male hormone panel results @ week 3 or so of PCT
2) My review of DSIP and whether I believe it contributed to a successful PCT.
Here is some info on DSIP for starters...I have not figured out how much to dose it at yet but I will figure that out soon enough.
DSIP (Delta Sleep-inducing Peptide) is a neuropeptide found in the hypothalamus, pituitary, and adrenal glands. Its isolation has allowed for extensive research which has found several possible primary and peripheral roles of this peptide. First, DSIP has been shown to induce sleep . Second, it has been used successfully to treat opiate and alcohol withdrawal . Third, it has been shown to work as an analgesic in treatment of chronic pain, sometimes as an adjunct treatment . Fourth, DSIP has been shown to block ACTH release and decrease levels of ACTH, stimulate LH release, and act as an inhibitor of the secretion of somatostatin . The source of production of DSIP is yet unknown; it may be produced in the central nervous system or in a peripheral organ. It is thought to pass through the blood-brain barrier (BBB) more easily than most known neuropeptides. As mentioned, DSIP has shown positive results in inducing slow-wave EEG (sleep). It has been shown to help treat narcolepsy and restore disturbed sleep patterns to normal sleep rhythms.

So basically, this stuff 1) Induces sleep 2) Is a chronic pain reliever, 3) helps kick various addictions and withdrawals, 4) blocks the hormone responsible for cortisol increases, 5) stimulates LH, and 6) blocks the hormone that inhibits GH release.
It just might be too good to be true...
