Overview

The Shredded Stack combines a triple-agonist GLP-1/GIP/glucagon (Retatrutide) for appetite suppression and metabolic drive, MOTS-c for mitochondrial fat oxidation, AC-262 to preserve (and potentially build) lean muscle in a deficit, and Enclomiphene to maintain natural testosterone during suppression.

This is not a beginner stack. Each component carries meaningful risk and requires careful monitoring.

Why this stack works

Retatrutide: Triple agonist (GLP-1 / GIP / glucagon) — the most aggressive metabolic driver currently available. Drives the caloric deficit through appetite suppression, satiety, and elevated energy expenditure.

MOTS-c: Mitochondrial-derived peptide that improves insulin sensitivity and fat oxidation. Pairs well with a GLP-1 by improving metabolic flexibility under deficit-induced stress.

AC-262: Non-steroidal SARM with a clean lean-mass preservation profile. In a deficit, its primary function is muscle preservation. Suppressive — hence the Enclomiphene.

Enclomiphene: Selective estrogen receptor modulator that maintains LH/FSH signalling, preventing testosterone from cratering during AC-262 suppression.

Items needed for this phase

  • EnclomipheneRx-grade preferred — supports HPTA during AC-262 suppression

Ancillaries throughout the cut:

  • AC-262 is suppressive — Enclomiphene + the PCT phase below cover recovery
  • Retatrutide: titrate slowly to avoid GI side effects
  • Liver support (TUDCA 250mg/day or NAC 600mg/day throughout)
  • Consider on-cycle testosterone support if libido drops
Phase 2
PCT
pctWk 1–44wk

Week 13–16: Nolvadex (Tamoxifen) 40/20/20/20mg/day or Clomid 50/25/25mg/day. Continue until bloodwork confirms HPTA recovery.

Items needed for this phase

  • Nolvadex (Tamoxifen)Rx required — primary SERM for PCT
  • Clomid (Clomiphene)Alternative SERM if Nolvadex is unavailable

Conclusion

The Shredded Stack delivers, but it demands respect. If you're running this, you should have bloodwork before, mid-cycle, and post-PCT. Know what you're doing. Don't skip the PCT.
