MK-677 solo vs stacking with CJC-1295 and ipamorelin, is the extra worth it?

Been looking at the so-called Superman stack (CJC-1295 + ipamorelin + MK-677) and honestly I keep wondering if the injectable part is doing much on top of the MK-677. MK-677 already keeps GH and IGF-1 elevated for 24 hours from one oral dose. So you're already getting sustained signalling day and night. Adding CJC and ipamorelin on top gives you a sharper pulse at night, sure, but does that extra pulse actually translate to more body comp change or just more water retention and numb hands?

I ran MK-677 solo for a while (around 12.5mg nightly) and the sleep depth was noticeably better for me, appetite went up a fair bit, and I held some water. Felt like recovery improved but could've been placebo or just sleeping deeper. Never stacked it with injectables so I can't compare firsthand.

The bit I keep pushing back on is the claim that you get "maximised GH output" from combining all three. Has anyone here actually done both MK-677 solo and then the full stack and felt a clear difference? Not just "I looked leaner" because that's so hard to separate from diet and training changes. Keen to hear from someone who kept variables fairly controlled. Reckon a lot of the perceived benefit might just be from the MK-677 doing the heavy lifting anyway.

  • sleep_coastal: 5 mg nightly for a couple months. Anecdotally I did wake up feeling a bit less stiff in the mornings and my fasting glucose seemed a touch lower, but I also noticed more overnight water gain and occasional hand tingling. Keeping diet and training steady was tough, so I can’t say if the extra pulse truly moved body composition or just added fluid. Curious if anyone tracked IGF‑1 levels pre‑ and post‑stack to see the actual bump.
  • student748: 5mg solo. The stiffness thing is interesting though, i wouldnt have expected that from mk-677 alone. Did you notice the tingling ease off after a while or did it stick around the whole time? Keen to know if its something you adapt to or just part of the deal.
  • fasted_scientist: Here's a thought: 5mg solo. The stiffness thing is interesting though, i wouldnt have expected that from mk-677 alone. Did you notice the tingling ease off after a while or did it stick around the whole time? Keen to know if its something you adapt to or just part of the deal. Honestly, that stiffness caught me off guard too. I noticed it creeping in around week 3, mostly in the mornings, like my joints felt a bit creaky without the usual "loosening up" after moving. The tingling in my hands, t
  • fasted_scientist: The hand tingling and water gain lines up with what I got on MK-677 solo tbh, so makes me wonder if the injectables are even adding much beyond what you'd already get from the oral alone. The fasting glucose bit is interesting though, I didn't track mine. Did you actually measure it or just going by feel? And yeah, the IGF-1 question is spot on, that's the bit that'd actually settle this. Reckon someone on here must have done pre and post bloods.
  • mel_b: The glucose thing is worth actually tracking because MK-677 solo is known to bump fasting glucose and reduce insulin sensitivity in the literature, not just anecdotally, so if someone stacks it and their glucose gets worse that's not necessarily the injectables causing it, could just be the MK doing its thing and the CJC/ipa layering on top. I'd wanna see IGF-1 pulled on MK solo vs MK plus injectables before claiming the stack adds anything real, because feeling better sleep or getting tingly ha
  • fasted_scientist: Yeah the glucose point is spot on, I never pulled fasting glucose during my solo run so I can't say whether it was already creeping up on just the MK. Ngl I was mainly going by how I felt which is exactly the problem you're describing. Has anyone here actually got IGF-1 numbers on both setups? That's the only way to settle whether the injectable layer adds anything measurable or if you're just paying extra for tingly hands.
