Who is Clavicular?
Clavicular (real name Braden Peters, born December 17, 2005) is the most influential figure in the peptide and looksmaxxing movement of 2025–2026. Starting on TikTok around 2021 before expanding to Kick livestreaming in 2025, Clav has amassed millions of followers with his dramatic physical transformation content.
His “Clavicular System” course ($50/month) includes guides on his peptide stack, making “clavicular peptides” one of the most searched terms in the peptide space in 2026.
Clavicular’s Exact Stack 2026
The peptides in Clavicular’s looksmaxxing protocol — broken down by mechanism and research data.
Retatrutide is the core of Clavicular’s stack and the reason his transformation went viral. Unlike Semaglutide (single GLP-1 agonist) or Tirzepatide (dual GIP/GLP-1), Retatrutide hits three receptors simultaneously — making it the most potent weight loss peptide in research to date.

Why Clav chose Retatrutide over Semaglutide or Tirzepatide: the triple-agonist mechanism addresses metabolic regulation, appetite suppression, AND energy expenditure through glucagon receptor activation. It’s the most aggressive body recomposition peptide available for research.
BPC-157 is Clavicular’s recovery peptide. It’s a 15-amino-acid peptide derived from human gastric juice that plays a key role in the stack for two reasons: gut protection while using Retatrutide (GLP-1 agonists can cause GI side effects in 38–43% of trial participants) and accelerated tissue healing.
Clavicular also uses Melanotan II for skin tanning. This peptide activates melanocortin-1 receptors (MC1R) to stimulate melanin production. However, it carries significant safety concerns including reports of renal infarction and rhabdomyolysis in the literature.

Frequently Asked Questions
What peptides does Clavicular take?
Clavicular’s core stack consists of Retatrutide (a triple-agonist targeting GLP-1, GIP, and Glucagon receptors) for body recomposition, BPC-157 for gut protection and recovery, and Melanotan II for tanning — though Melanotan II is not recommended due to safety concerns. See Melanotan 1 as a safer alternative at Boss Peptides.
Where can I buy Clavicular’s peptides in Canada?
You can buy Retatrutide and BPC-157 — the core of Clavicular’s stack — from Boss Peptides. All products are manufactured in Canada, verified at >99% purity by HPLC and mass spectrometry, and ship same-day across Canada with free shipping on orders over $150.
How much does Clavicular’s peptide stack cost in Canada?
Clavicular’s core stack (Retatrutide 6mg + BPC-157 5mg) costs approximately $133.98 CAD from Boss Peptides. A budget alternative using Semaglutide instead of Retatrutide starts at approximately $98.98 CAD. Free shipping applies on orders over $150.
Is Retatrutide better than Semaglutide?
Retatrutide is a triple-agonist (GLP-1/GIP/Glucagon) while Semaglutide only targets GLP-1. In clinical trials, Retatrutide showed −24.2% weight loss at 48 weeks in Phase 2, advancing to −28.7% at 68 weeks in TRIUMPH-4 Phase 3. Semaglutide averages ~15%. That’s why Clavicular chose Retatrutide as his primary peptide.
Why does Clavicular use BPC-157?
BPC-157 serves as Clavicular’s recovery peptide. GLP-1 agonists like Retatrutide commonly cause GI side effects (nausea in 38–43% of participants). BPC-157’s gastroprotective properties via the VEGFR2 pathway help manage these effects while simultaneously promoting tissue healing and recovery from training.
Is Boss Peptides partnered with Clavicular?
No. Boss Peptides is not partnered with or endorsed by Clavicular (Braden Peters). Boss Peptides is an independent Canadian peptide manufacturer. This page provides information about the research peptides Clavicular has publicly discussed using.
Are these peptides safe?
All products from Boss Peptides are sold for research purposes only, not for human consumption. Retatrutide showed an 18.2% discontinuation rate at 12mg in Phase 2 trials, primarily due to GI side effects. Boss Peptides products are verified at >99% purity by HPLC and mass spectrometry. Always consult a healthcare professional regarding any peptide research.
What is the Clavicular System?
The Clavicular System is Clavicular’s $50/month subscription course that includes guides on his peptide protocol, fitness routines, and looksmaxxing techniques. This page provides free information about the research peptides he uses, available from Boss Peptides in Canada.
