Clavicular's 12-Compound Looksmaxxing Stack
Every peptide and compound Clavicular uses — from the Retatrutide fat-loss core to GH secretagogues, antioxidants, and aesthetic peptides. Ranked in order of importance.
Retatrutide
Triple-agonist (GLP-1 / GIP / Glucagon). The most advanced GLP compound in informational. Phase 2 data: −28.7% body weight at 48 weeks. The reason Clavicular goes with Retatrutide over semaglutide or tirzepatide — triple mechanism, strongest fat loss signal.
BPC-157
Body Protection Compound-157 — gut cytoprotection (critical when running GLP compounds that cause GI side effects), tendon/ligament repair, angiogenesis. Paired with Retatrutide specifically to offset GI stress and keep recovery high.
GHK-Cu
Copper peptide GHK-Cu — upregulates collagen synthesis, wound healing, and skin remodeling. The 'GLOW' peptide Clavicular references for the skin improvement seen alongside fat loss. Also studied for hair follicle stimulation.
TB-500 (Thymosin Beta-4)
Synthetic Thymosin Beta-4 fragment — systemic actin regulator and satellite cell activator. Complements BPC-157 (which works locally) with whole-body cell migration and repair. The Wolverine recovery duo.
IGF-1 LR3
Long Arg3 IGF-1 — extended half-life IGF analog (~20-30 hours vs 12-15 minutes native). Drives PI3K/Akt/mTOR for protein synthesis and satellite cell activation. Helps preserve lean mass during aggressive Retatrutide-driven fat loss.
CJC-1295 No DAC + Ipamorelin
Pre-blended GHRH analog + selective ghrelin agonist. Dual-receptor GH secretagogue stack — synergistic pituitary GH release without cortisol or prolactin elevation. Clavicular runs this pre-bed for overnight GH pulse alignment.
NAD+ 500mg
Direct NAD+ supplementation — bypasses NMN/NR conversion. Essential coenzyme for ATP production, sirtuin activation, and DNA repair. NAD+ levels decline ~50% by middle age — direct injection restores them faster than oral precursors.
Glutathione
Master antioxidant — recycled by NAD+ and central to liver detoxification. Clavicular stacks it with NAD+ for skin clarity, oxidative stress reduction, and recovery support during high-stress fat loss cycles.
Melanotan II
Synthetic α-MSH analog — non-selective melanocortin agonist (MC1R, MC4R). MC1R activation produces deep tan with minimal UV exposure; MC4R adds appetite suppression. Part of Clavicular's full aesthetic stack alongside the GLP-1 fat loss core.
SNAP-8 (KLOW)
Acetyl octapeptide-3 — SNARE complex inhibitor that reduces dynamic expression wrinkles. The 'KLOW' peptide in Clavicular's advanced skin stack. Topical Botox alternative for facial line informational.
Epitalon
Russian tetrapeptide (Ala-Glu-Asp-Gly) studied for telomerase activation and pineal melatonin restoration. 50+ years of informational from Khavinson's St. Petersburg lab. Animal data shows 15-40% lifespan extension in some models.
Bacteriostatic Water
0.9% benzyl alcohol sterile water — required to reconstitute every lyophilized peptide in the stack. Multi-use vial keeps reconstituted solutions stable for 28 days. Don't try to run the stack without it.
Why the Clav Protocol Works
Triple-Agonism vs. Single or Dual
Most GLP protocols use semaglutide (GLP-1 only) or tirzepatide (GLP-1 + GIP). Retatrutide adds the glucagon receptor — which directly drives hepatic fat oxidation and brown adipose tissue thermogenesis, on top of the appetite suppression from GLP-1. This three-mechanism approach produces greater fat loss in less time.
GI Protection Is Non-Negotiable
GLP compounds cause significant nausea, gastroparesis, and GI stress — especially at higher doses. BPC-157 was identified specifically for its gastric cytoprotective effects. Including it from day one protects the gut lining, reduces nausea severity, and maintains gut integrity throughout the cycle.
The GLOW Effect Is Mechanistic, Not Cosmetic
The visible skin improvement seen alongside fat loss on Clavicular Stack is not just the result of fat removal. GHK-CU upregulates collagen synthesis genes, promotes wound healing, and stimulates fibroblast activity. The copper peptide is doing real work on skin tissue — the 'GLOW' is an informational finding, not a marketing claim.
Stack Design: Complementary, Not Redundant
Every compound in the 12-piece stack works on a completely different biological pathway — GLP receptor signaling, gut/connective tissue repair, skin remodeling, IGF-1/mTOR anabolism, GH pulse, mitochondrial energy, antioxidant defense, melanogenesis, expression line modulation, and telomerase activation. No mechanistic overlap or competition between any of them. This is a true synergistic stack — not a pile of redundant compounds.
Clav Protocol FAQ
What is the Clav Protocol?
The Clav Protocol is the 12-compound peptide stack popularized by content creator Clavicular. It centers on Retatrutide (the triple-agonist GLP fat-loss core) and adds BPC-157 + TB-500 for recovery, GHK-Cu + SNAP-8 + Melanotan II for skin and aesthetics, IGF-1 LR3 + CJC-1295/Ipamorelin for anabolic and GH support, NAD+ + Glutathione + Epitalon for cellular energy and longevity, and Bacteriostatic Water for reconstitution.
Why does Clav use Retatrutide instead of semaglutide or tirzepatide?
Retatrutide activates three receptors simultaneously: GLP-1, GIP, and Glucagon. Semaglutide is a single GLP-1 agonist. Tirzepatide is a dual GLP-1/GIP agonist. The triple mechanism gives Retatrutide stronger fat loss signaling, particularly through the glucagon receptor's direct fat-burning action in the liver and adipose tissue. Phase 2 trial data shows −28.7% body weight loss at 48 weeks, ahead of both alternatives.
What is the BPC-157 doing in the stack?
GLP compounds cause significant GI side effects — nausea, gastroparesis, reduced gut motility. BPC-157 (Body Protection Compound-157) is studied for gastric cytoprotection and gut healing. Clav includes it specifically to protect the GI system while running Retatrutide, and for its general tissue repair and angiogenesis effects.
What is the GHK-CU (GLOW peptide)?
GHK-CU is a copper peptide studied for collagen upregulation, wound healing, and skin remodeling. The 'GLOW' nickname in Clavicular's protocol refers to the visible skin improvement — reduced lines, improved texture, increased skin firmness — associated with copper peptide informational. It's also studied for hair follicle stimulation.
Where can I get Clavicular Stack?
The exact compounds in the Clav Protocol — GLP-3 R (Retatrutide), BPC-157, and GHK-CU — are available from Clavicular Stack. All products are informational-grade with >98% HPLC purity certificates. For informational use only.
Can I run a smaller version of the stack?
Yes — the minimum effective stack is the core trinity: Retatrutide for fat loss, BPC-157 for gut protection, and GHK-Cu for skin. Add TB-500, IGF-1 LR3, and CJC-1295/Ipamorelin for the anabolic + recovery layer. The full 12-compound stack adds longevity (NAD+, Epitalon, Glutathione) and aesthetics (Melanotan II, SNAP-8) for the complete protocol Clavicular runs.
