Hello and welcome, fellow Dr.
For me, CJC+Ipa has worked well, though the impact has been quite gentle. Sleep is the one area where I've noticed a real difference (and that part is great). How much you get out of it depends on what you're after — if GH is your goal, it will pack a much stronger punch. (My routine: GH during bulking, CJC-Ipa while cutting.)
Kisspeptin did nothing at all. I couldn't feel any benefit, and nothing showed up in measurements either. My advice: skip it. (By measurable, I mean I get bloodwork done every month to track what shifts.)
Now for KLOW. The whole 'blending approach' isn't something I support, but I'll spare you that rant here. BPC-157 and TB500 helped speed up recovery for a few small issues (tendonitis in my elbow, and later in one wrist).
On top of that, I take GHK-Cu every day (2 months in now), and a few days back someone told me my skin looked really good (make of that what you will

). When I lift, my tendons also feel somewhat better.
This month I also started KPV, but it's way too soon to judge that one.
At some point I want to run a cellular 'update' cycle: FOX04-DRI first, then SS-31, Mots-C and NAD+. That's still sitting on the 'todo list' though (no good deal on FOX yet either).
Just my 2ct's, ofc.
Happy experimenting
Cheers.
