Clav's Three Core Peptides
Each compound targets a specific research pathway — fat loss, recovery, and skin.
GLP-3 R · Retatrutide
Triple-agonist (GLP-1 / GIP / Glucagon). The most advanced GLP compound in research. Phase 2 data: −28.7% body weight at 48 weeks. The reason Clav goes with Retatrutide over semaglutide or tirzepatide — triple mechanism, strongest fat loss signal.
BPC-157 · 10mg
Body Protection Compound-157 — gut cytoprotection (critical when running GLP compounds that cause GI side effects), tendon/ligament repair, angiogenesis. Clav pairs it with Retatrutide specifically to offset GI stress and keep recovery high.
GHK-CU · 50mg
Copper peptide GHK-CU — upregulates collagen synthesis, wound healing, and skin remodeling. The 'GLOW' peptide Clav references for the skin improvement seen alongside fat loss. Also studied for hair follicle stimulation.
Extended Clav Stack
Optional add-ons for serious researchers running the full looksmax protocol.
TB-500 (TB500 10mg)
Thymosin Beta-4 — deeper tissue repair and inflammation modulation. Often combined with BPC-157 in the Wolverine recovery protocol.
View ProductSNAP-8 (KLOW Peptide)
Acetyl octapeptide studied for expression wrinkle reduction via acetylcholine modulation. The 'KLOW' skin peptide in Clav's advanced protocol.
View ProductCJC-1295 / Ipamorelin
Growth hormone secretagogue blend. Supports overnight GH pulse for improved body composition, sleep quality, and recovery.
View ProductNAD+ 500mg
Nicotinamide adenine dinucleotide — cellular energy metabolism and mitochondrial support. Studied for anti-aging and metabolic optimization.

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 Clav's 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 a research finding, not a marketing claim.
Stack Design: Complementary, Not Redundant
Each of the three core peptides works on a completely different biological pathway — GLP receptor signaling, gut/connective tissue repair, and skin remodeling. There is no mechanistic overlap or competition between them. This is a true synergistic stack.
Clav Protocol FAQ
What is the Clav Protocol?
The Clav Protocol is the research peptide stack popularized by the content creator Clavicular. It centers on Retatrutide (GLP-3 R) as the primary fat loss compound — a triple-agonist GLP peptide — paired with BPC-157 for gut protection and recovery, and GHK-CU (copper peptide) for skin and the 'GLOW' effect.
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 research. It's also studied for hair follicle stimulation.
Where can I get Clav's 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 research-grade with >98% HPLC purity certificates. For research use only.
Is there an advanced version of the Clav stack?
Yes. The extended protocol adds TB-500 (Thymosin Beta-4) for deeper tissue recovery, and SNAP-8 (the 'KLOW' skin peptide) for expression wrinkle reduction. Some researchers also add NAD+ for cellular energy and a GH secretagogue like CJC-1295/Ipamorelin for overnight GH pulse support.
