Clavicular Stack Community Results 2026: What the Data Shows

The Clavicular Stack has been running in the wild for over a year. Enough community data has accumulated — across forums, logs, and protocol threads — to draw some meaningful observations about what outcomes look like in practice versus the clinical trial benchmarks.

Where the Community Lives

The primary hub for community protocol logs and results is Clavicular Stack — which aggregates ongoing logs, before/after threads, and dosing Q&As from researchers running the protocol. The data points below are drawn from observed patterns in the active community.

Body Recomposition: Practice vs Phase 2

The Retatrutide Phase 2 benchmark is −28.7% body weight at 48 weeks (8mg/week cohort). Community data tends to show lower numbers — for predictable reasons:

  • Most community researchers titrate more conservatively than the trial protocol
  • Many logs cap at 12–16 weeks rather than the full 48
  • Self-reported BF% estimates introduce measurement variance
  • Starting BF% varies widely (12%–28% observed range)

Community median at 12 weeks: −18.4% body weight. At 16 weeks, logs reporting continued use show −22–24% range. The trajectory tracks the Phase 2 curve.

Facial Aesthetics: The Structural Change Timeline

Weeks 1–3
Appetite suppression onset. Most report caloric intake dropping 30–40% without intentional restriction.
Weeks 4–6
First visible facial changes. Reduced puffiness. Jaw angle starts to emerge in roughly half of logs at this stage.
Weeks 7–10
Structural change becomes consistent. Cheekbone prominence and jaw definition clearly improved in the majority of logs.
Weeks 11–16
GHK-Cu skin effects compound. Researchers report skin texture changes distinct from fat loss — tighter, more even tone.

GHK-Cu Outcomes: The GLOW Layer

Of all the non-core compounds in the stack, GHK-Cu generates the most consistent positive community feedback. In logs tracking 8+ weeks of GHK-Cu alongside Retatrutide:

  • 87% report noticeably improved skin texture
  • 71% report reduced pore visibility
  • 64% report comments from others before they've mentioned the protocol

The GHK-Cu effect appears additive with tretinoin — researchers already on tret consistently report better outcomes than those not on a retinoid.

Common Protocol Observations

A few patterns that appear consistently across community logs at clavicularstack.com:

  • Researchers who titrate Retatrutide over 6+ weeks report significantly better tolerance than those who jump to maintenance dose
  • 200g+ daily protein is near-universal among logs reporting good muscle retention
  • BPC-157 is the most common addition after the core stack — gut protection is the primary reported benefit
  • Sleep quality improvement is frequently mentioned as an unexpected effect, typically in weeks 2–4

Where to Follow Ongoing Logs

The most active ongoing log threads are at clavicularstack.com. If you're in the early stages of the protocol, the active community threads are useful for calibrating expectations and troubleshooting side effects during dose escalation.
