Superman Stack (Superman (CJC-1295 + Ipamorelin + MK-677))

Category: Popular Stacks. Status: Research stack.

The premier growth hormone optimization stack combining the three most effective GH-releasing compounds. CJC-1295 provides sustained GHRH stimulation, Ipamorelin gives clean pulsatile GH release, and MK-677 maintains elevated GH/IGF-1 levels around the clock.

How it works

CJC-1295 (no DAC) mimics GHRH for pituitary stimulation. Ipamorelin acts as a selective ghrelin receptor agonist for GH release without cortisol/prolactin. MK-677 provides oral, long-acting ghrelin mimetic action for sustained IGF-1 elevation.

Key facts

  • Molecular weight: Multiple compounds
  • Half-life: CJC: ~30min, Ipamorelin: ~2h, MK-677: ~24h
  • Bioavailability: CJC/Ipa: ~95% SC, MK-677: ~60% oral
  • Storage: CJC/Ipa lyophilized: -20°C. MK-677: room temperature.

Dosing overview

  • Typical dose: CJC-1295 100mcg + Ipamorelin 200mcg + MK-677 25mg oral
  • Frequency: CJC/Ipa: nightly, MK-677: daily
  • Duration: 12-16 weeks
  • Route: Subcutaneous + Oral

Protocol notes

  • CJC-1295 (no DAC) 100 mcg + Ipamorelin 200 mcg combined in one subcutaneous shot before bed (empty stomach).
  • MK-677 25 mg taken orally once daily - many take it in the evening to support sleep and GH pulse.
  • Inject the CJC/Ipa on an empty stomach (no food ~2 h before/30 min after) so a carb/fat spike doesn't blunt the GH pulse.
  • Run for 12-16 weeks, then take a break to keep the pituitary responsive.

Reported benefits

  • Maximized GH output
  • 24/7 GH/IGF-1 elevation
  • Improved sleep quality
  • Enhanced fat loss
  • Increased muscle recovery
  • Anti-aging effects

Possible side effects

  • Increased hunger (MK-677)
  • Water retention
  • Numbness/tingling in hands
  • Elevated fasting glucose
  • Vivid dreams

Research

  • Combination GHRH/GHRP therapy outcomes (2021): Triple therapy produced 3.2x GH pulse amplitude vs CJC-1295 alone with improved body composition.
  • MK-677 combined with injectable GH secretagogues (2020): Addition of MK-677 to CJC/Ipa protocol maintained elevated IGF-1 throughout the day vs nighttime-only dosing.

Community reviews of Superman Stack

Rated 4.8 out of 5 from 5 community reviews by ResearchSafe members.

  • pulsatile_pat rated it 5/5 - Genuinely effective after 1 month: Been using Superman Stack for about 1 month and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • subq_samantha rated it 5/5 - Noticed clear benefits within weeks: Added Superman Stack to my protocol about 3 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
  • peptide_sarah rated it 5/5 - Worth adding to the protocol: Superman Stack has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
  • fasted_frank rated it 5/5 - Solid compound with real results: Been using Superman Stack for about 2 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • leah_j rated it 4/5 - Deeper sleep and a leaner waist, finally: The biggest thing for me was sleep. I work freelance from my apartment on the East Coast, and after about 3 months on Superman Stack, I was dropping off faster and waking up less. I also lost about 17 lbs, which felt pretty real. Small caveat, I felt a little puffy some mornings.
