Clavicular Stack FAQ

Clavicular (real name Braden Peters) is one of the most influential figures in the looksmaxxing and peptide community. He gained massive popularity on TikTok and Kick in 2025 for documenting his physical transformation using peptides, skincare, and lifestyle optimization. His content focuses on aesthetic self-improvement through research peptides.

Clavicular (Braden Peters) was born on December 17, 2005. He rose to fame in his late teens, becoming the face of the looksmaxxing peptide movement by 2025.

Clavicular is known for his dramatic physical transformation and for popularizing peptide use in the looksmaxxing community. He openly documents his peptide stack, skincare routine, and body recomposition journey on social media, making him the most recognized figure in the peptide/looksmaxxing space.

Looksmaxxing is the practice of maximizing your physical appearance through every available method — skincare, fat loss, muscle building, grooming, and in Clavicular's case, research peptides. The goal is to optimize facial aesthetics, body composition, and overall appearance.

Clavicular streams primarily on Kick and posts content on TikTok. He also has a presence on YouTube and Instagram where he shares transformation updates and protocol breakdowns.

Clavicular's core peptide stack includes Retatrutide (GLP-3 R) as the primary fat-loss compound, BPC-157 for gut protection and recovery, GHK-Cu (the "GLOW" peptide) for skin quality, and TB-500 for tissue repair. He has also mentioned using NAD+, CJC-1295/Ipamorelin, and SNAP-8 for additional benefits.

Retatrutide (also called GLP-3 R) is Clavicular's primary peptide. It's a triple-receptor agonist that activates GLP-1, GIP, and Glucagon receptors simultaneously — making it the most potent weight-loss peptide in research. Phase 2 trials showed -28.7% body weight loss at 48 weeks.

The Clavicular Stack is the exact combination of peptides Clavicular uses for his looksmaxxing protocol. The core stack is: Retatrutide (GLP-3 R) for fat loss, BPC-157 for gut health and recovery, and GHK-Cu for skin quality. The full "Ultimate" version adds TB-500, SNAP-8, CJC-1295/Ipamorelin, and NAD+.

Retatrutide is a triple-agonist (GLP-1 + GIP + Glucagon) vs semaglutide (Ozempic) which only hits GLP-1. The triple mechanism produces significantly more fat loss — 28.7% vs 14.9% in clinical trials. The glucagon receptor engagement also drives direct hepatic fat oxidation and brown adipose thermogenesis, which semaglutide cannot do.

GLP-1 agonists like Retatrutide cause GI side effects — nausea, gastroparesis, and gut discomfort during dose escalation. BPC-157 is a cytoprotective peptide that supports gut health, protects the GI lining, and aids tissue repair. Clavicular pairs it with Retatrutide specifically to manage these side effects.

The "GLOW" peptide is GHK-Cu (copper peptide). Clavicular uses it for skin tightening, collagen stimulation, and anti-aging effects. As you lose body fat rapidly on Retatrutide, GHK-Cu helps maintain skin elasticity and quality — which is critical for the looksmaxxing aesthetic.

Clavicular has openly discussed using testosterone replacement therapy (TRT) and Anavar alongside his peptide stack. These are separate from the research peptide protocol. The Clavicular Stack specifically refers to his peptide combination — Retatrutide, BPC-157, GHK-Cu, and supporting compounds.

Yes, Clavicular has mentioned using Melanotan II, a tanning peptide that produces a deep tan without sun exposure. This is separate from his core looksmaxxing peptide stack but part of his broader aesthetic protocol.

The Budget Stack uses Tirzepatide (dual-agonist, ~$140) + CJC-1295 (~$65) for ~$205/month. Clavicular's actual stack uses Retatrutide (triple-agonist) + BPC-157 + GHK-Cu for more comprehensive results but at a higher cost. The Budget Stack is a good starting point, but Clavicular Stack is the full protocol.

Yes. Clavicular has evolved his protocol as new compounds became available. Retatrutide replaced earlier GLP-1 compounds as the core fat-loss peptide when it became accessible. He has also added skin-focused peptides like GHK-Cu and SNAP-8 as his protocol shifted from pure fat loss to full aesthetic optimization.

The core Clavicular Stack (Retatrutide + BPC-157 + GHK-Cu) costs approximately $300-$450/month depending on doses. The Budget Stack entry point is ~$205/month. The full Ultimate Stack with all compounds can run $500-$700/month. Prices vary by supplier and quantity purchased.

Clavicular sources research-grade peptides from suppliers that provide third-party purity testing and certificates of analysis. We partner with Apollo Peptide Sciences, which offers >98% HPLC-verified purity on all compounds in Clavicular Stack.

The cheapest entry is the Budget Stack (~$205/month) using Tirzepatide instead of Retatrutide. For Clavicular Stack's actual protocol on a budget, start with just Retatrutide + BPC-157 (skip GHK-Cu initially) and buy larger vial sizes for better price-per-mg. The 60mg Retatrutide vials offer the best value.

Research peptides are legal to purchase in the US for research purposes. They are sold as "research chemicals" and are not FDA-approved for human use. Clavicular's stack compounds — Retatrutide, BPC-157, GHK-Cu, TB-500 — are all available as research peptides.

Look for suppliers that provide third-party certificates of analysis (COA) with HPLC purity testing showing >98% purity. Reputable suppliers also offer mass spectrometry verification. Avoid suppliers without COAs, those with prices that seem too good to be true, or those selling pre-mixed ready-to-inject solutions.

Clavicular follows a dose-escalation protocol: Week 1-4 at 2mg/week, Week 5-8 at 4mg/week, then 8mg/week ongoing. This mirrors the Phase 2 clinical trial escalation schedule. The gradual increase helps minimize GI side effects.

BPC-157 is typically administered via subcutaneous injection at 250-500mcg per day. Clavicular starts BPC-157 from Week 1 — before Retatrutide dose escalation begins — to establish GI protection before GLP-1 side effects ramp up.

Clavicular's Retatrutide protocol runs 12+ weeks minimum. The dose escalation phase takes 8 weeks, with the full 8mg dose from Week 9 onward. BPC-157 runs the entire duration. Most results are visible by Week 12, but the Phase 2 trial showed continued progress through 48 weeks.

All lyophilized (freeze-dried) peptides are reconstituted with bacteriostatic water. Add the water slowly down the side of the vial, then gently swirl — never shake. Store reconstituted peptides at 2-8°C (fridge) and use within 4-6 weeks. We have a full step-by-step reconstitution guide on our site.

Retatrutide is injected once weekly (subcutaneous). BPC-157 is daily (subcutaneous). GHK-Cu can be applied topically daily or injected 2-3x per week depending on protocol. TB-500 is typically 2x per week during the loading phase, then weekly for maintenance.

Subcutaneous peptide injections use insulin syringes — typically 29-31 gauge, 1/2 inch needles with 1mL syringes. These are the same syringes used for insulin and are widely available. Injection sites are typically the abdomen or thigh.

No. Peptides like Retatrutide, BPC-157, and GHK-Cu are degraded by stomach acid and digestive enzymes if taken orally. Subcutaneous injection is required for bioavailability. Oral peptide supplements sold online are not the same compounds and will not produce the same results.

Retatrutide dose escalation: 2mg (weeks 1-4) → 4mg (weeks 5-8) → 8mg (weeks 9+). BPC-157: 250-500mcg daily from day 1. GHK-Cu: daily topical or 2-3x/week injection. This gradual ramp minimizes nausea and GI side effects from GLP-1 activation.

Clavicular's transformation includes dramatic fat loss, improved body composition, enhanced skin quality, and overall aesthetic improvement. His before/after documented on social media shows significant visible changes within 12 weeks of his Retatrutide-based protocol.

Most people notice appetite suppression within the first week of Retatrutide. Visible fat loss typically becomes noticeable by weeks 4-6. Significant body composition changes appear by weeks 8-12. Skin improvements from GHK-Cu develop over 2-4 weeks with injections, 2-3 months topically.

Research peptides carry inherent risks as they are not FDA-approved for human use. Retatrutide's Phase 2 trial showed manageable side effects (primarily GI), but long-term safety data is still being collected in Phase 3 trials. BPC-157 and GHK-Cu have favorable safety profiles in published research but limited human clinical data. Consult a healthcare provider before using any research compounds.

The most common side effects come from Retatrutide: nausea, reduced appetite, occasional GI discomfort — especially during dose escalation. This is why BPC-157 is included in the stack for gut protection. Other peptides (GHK-Cu, TB-500) have minimal reported side effects in research literature.

Clavicular has discussed infertility, but this is attributed to anabolic steroid use (testosterone, Anavar), not the peptide stack itself. GLP-1 agonists like Retatrutide do not have established effects on fertility. However, combining multiple compounds without medical supervision carries unpredictable risks.

GLP-1 agonists can cause some lean mass loss alongside fat loss. Clavicular mitigates this with resistance training and adequate protein intake. CJC-1295/Ipamorelin in the full stack supports growth hormone secretion which helps preserve muscle during aggressive fat loss.

Like all GLP-1 agonists, stopping Retatrutide can lead to appetite returning and potential weight regain if diet and exercise habits haven't been established. The key is using the peptide cycle to build sustainable habits. Some people run maintenance doses at lower levels rather than stopping completely.

No. Retatrutide is currently in Phase 3 clinical trials conducted by Eli Lilly. FDA approval could potentially come in late 2026 or 2027 depending on trial results. It is currently available only as a research peptide, not a prescription medication.

The peptide compounds in Clavicular's stack (Retatrutide, BPC-157, GHK-Cu) are not gender-specific in their mechanisms. Women can research the same compounds. However, dosing may differ, and women should be especially cautious with any hormonal compounds. Consult a healthcare provider.

GLP-1 agonists are not currently on WADA's prohibited list. However, BPC-157 is banned by WADA and USADA as a prohibited peptide hormone. Athletes subject to anti-doping testing should not use BPC-157 or other peptides that appear on the prohibited substance list.

Ozempic (semaglutide) is a GLP-1 single agonist — one receptor. Mounjaro (tirzepatide) is a GLP-1/GIP dual agonist — two receptors. Retatrutide is a GLP-1/GIP/Glucagon triple agonist — three receptors. More receptors = more mechanisms of fat loss. Trial data: semaglutide -14.9%, tirzepatide -20.9%, Retatrutide -28.7%.

BPC-157 is a gastric peptide that works locally at injury sites, focusing on gut protection, tendon repair, and anti-inflammation. TB-500 (Thymosin Beta-4) works systemically throughout the body, promoting cell migration and reducing inflammation everywhere. Clavicular uses both for complementary recovery coverage.

GHK-Cu is a copper peptide that stimulates collagen production, improves skin elasticity, and promotes wound healing. During rapid fat loss on Retatrutide, skin can become loose or lose quality. GHK-Cu counteracts this — it's the "GLOW" peptide in Clavicular Stack specifically for maintaining skin aesthetics during aggressive cutting.

SNAP-8 is a topical peptide that reduces the appearance of expression wrinkles by modulating the SNARE complex involved in muscle contraction. Think of it as a topical alternative to Botox. It's used in the Ultimate Stack for facial aesthetics — reducing forehead lines and crow's feet.

CJC-1295/Ipamorelin is a growth hormone secretagogue combination. CJC-1295 (No DAC) stimulates the GHRH receptor, and Ipamorelin stimulates the ghrelin receptor. Together they boost natural growth hormone release, which supports fat loss, muscle preservation, recovery, and skin health.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme essential for cellular energy production and DNA repair. NAD+ levels decline with age. Supplementing it supports mitochondrial function, energy, and cellular repair — Clavicular includes it in his longevity-focused protocol alongside the core looksmaxxing compounds.

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. You absolutely need it to reconstitute any lyophilized (freeze-dried) peptide. It prevents bacterial growth in the vial after reconstitution, keeping your peptide solution safe to use for 4-6 weeks when refrigerated.

Unreconstituted (powder): store at -20°C (freezer) for long-term, or 2-8°C (fridge) for up to 12 months. Reconstituted (liquid): always refrigerate at 2-8°C and use within 4-6 weeks. Never freeze reconstituted peptides. Avoid repeated freeze-thaw cycles with powder vials.

Yes — that's exactly what Clavicular does. His stack combines peptides with different mechanisms: Retatrutide for fat loss, BPC-157 for gut/recovery, GHK-Cu for skin. Each targets a different pathway so they complement rather than compete. However, each peptide should be reconstituted and injected separately — never mix vials.

Always look for >98% purity verified by HPLC (High Performance Liquid Chromatography) testing. Reputable suppliers provide certificates of analysis (COA) with each batch. Mass spectrometry confirmation of molecular weight is an additional quality indicator. Never buy peptides without COA documentation.
