Claviculars Peptides Review: Inside the 143-Compound Research Catalog

The research peptide market is crowded, and separating serious vendors from the rest comes down to three things: catalog depth, verifiable purity, and the quality of the information a supplier publishes about the compounds they sell. Claviculars Peptides is one of the few vendors that invests in all three — a 143-compound catalog spanning every major research category, >98% HPLC purity with third-party test reports, and a documented "5-Layer Research Architecture" that organizes their flagship protocol around compounds with non-overlapping mechanisms.

This is a full look at what they offer, how they're positioned, and which products stand out.

Brand Positioning: Research Protocols, Not Just Products

Most peptide vendors sell lists of compounds. Claviculars structures their catalog around research protocols — their "5-Layer Research Architecture" pairs compounds from metabolic, healing, skin, and growth-hormone categories so that each addresses a distinct pathway without overlapping signaling. Their featured stack is built from five anchors:

• GLP-3 R (Retatrutide) 15mg — the triple-receptor agonist at the center of recent metabolic research
• BPC-157 10mg — the canonical healing peptide
• GHK-Cu 50mg — copper tripeptide for skin and collagen
• SNAP-8 10mg — an octapeptide targeting SNARE complex signaling
• CJC-1295 / Ipamorelin blend — the standard growth hormone secretagogue stack

Quality & Testing Claims

Every product page on clavicularspeptides.com references the same baseline standards: HPLC purity above 98%, verified CAS numbers, and third-party test reports available on request. Free shipping applies on orders over $200, and every product carries a prominent research-use-only disclaimer. These are the baseline table stakes for a legitimate vendor, and Claviculars meets them — the differentiator is not that they test, but that they publish their methodology in a way most vendors don't.

The GLP Class: Retatrutide, Tirzepatide, Semaglutide

Claviculars' metabolic catalog is one of the most complete in the market. The headline compound is Retatrutide (GLP-3 R), a triple-agonist hitting GLP-1, GIP, and glucagon receptors simultaneously — Phase 2 trials showed −28.7% weight reduction, numbers that outperform anything currently on the market. Multiple vial sizes are available including 10mg, 30mg, and 60mg for researchers running extended protocols.

The Tirzepatide (GLP-2 T) line covers the dual GIP/GLP-1 agonist class in 15mg, 30mg, 60mg, and multi-pack configurations for longer cycles. For the single-agonist class, Semaglutide (GLP-1 S) is available in 5mg, 10mg, and 15mg vials.

They also carry the newer Cagrilintide and combination analogs — Cagri-Reta, Reta-Cagri, and standalone Cagrilintide — compounds that have been getting attention in research circles for their amylin-based appetite modulation.

Fat Loss & Metabolic Niche Compounds

Beyond the GLP class, Claviculars stocks a surprising range of metabolic research compounds that most vendors don't carry:

• AOD-9604 — the HGH C-terminal fragment for targeted lipolysis without IGF-1 elevation (also in 5mg and 2mg)
• Mazdutide and Survodutide — emerging dual and triple agonists under active investigation
• 5-Amino-1MQ — NNMT inhibitor for NAD+ preservation and metabolic flexibility
• Tesofensine — central monoamine reuptake inhibitor for appetite research
• SLU-PP-332 — the ERR agonist emerging from exercise-mimetic research
• BAM-15 — mitochondrial uncoupler for thermogenic research

Healing, Recovery & Gut Repair

The healing peptide section is what every serious research catalog should look like. BPC-157 10mg is the flagship, and they carry BPC-157 capsules for oral/gut-targeted protocols. TB-500 10mg is stocked alongside pre-mixed BPC-157/TB-500 blends — the standard combination for connective tissue and soft-tissue injury research.

Skin, Glow & Aesthetic

GHK-Cu 50mg is the anchor compound, with a 100mg option for extended protocols. SNAP-8 (and the 2-pack) targets SNARE complex signaling at the neuromuscular junction for expression-line research. Their proprietary Glow Blend and Klow Blend formulations combine GHK-Cu with complementary compounds.

The melanocortin class rounds out the skin catalog: Melanotan 2 and Melanotan 1 for pigmentation research, PT-141 for libido-focused protocols, and RU-58841 — the topical androgen receptor antagonist relevant to hair-loss research.

Growth Hormone Axis

The GH secretagogue section covers the complete range. The pre-blended CJC-1295 / Ipamorelin is the community default, but they also stock standalone Ipamorelin 10mg, CJC-1295 no-DAC, CJC-1295 with DAC, Sermorelin (available in 2mg, 5mg, 10mg), and Tesamorelin for visceral fat-focused research.

The older-generation GHRPs are also stocked: GHRP-2, GHRP-6, and Hexarelin — useful for comparative research against modern ipamorelin-family compounds.

Longevity, Anti-Aging & NAD

Epithalon 50mg is the centerpiece here, stocked alongside Epitalon 10mg and the injectable Na-Epitalon for extended protocols targeting telomerase activation.

The NAD+ line is serious: NAD+ 500mg and 1000mg vials alongside Glutathione at multiple strengths, Methylene Blue, and the exotic FOXO4-DRI senolytic peptide — a compound most vendors don't carry and which has some of the most interesting recent longevity data.

Recovery, Immune & Mitochondrial

Thymosin Alpha-1 and MOTS-c lead this section, with MOTS-c stocked in 10mg, 20mg, and 40mg for researchers scaling protocols. The SS-31 (Elamipretide) line targeting cardiolipin and mitochondrial function is particularly strong, available in 10mg, 25mg, and 50mg.

Other standouts: KPV, ARA-290, LL-37, VIP, Thymulin, and Kisspeptin-10.

Cognitive & Mood

The nootropic catalog is well-stocked. Selank and the amidate variants N-Acetyl Selank and N-Acetyl Semax Amidate are the headliners. DSIP covers sleep research, Oxytocin for social-bonding protocols, and the more experimental P21 and PE-22-28 fill out the neurogenesis research options.

Khavinson Bioregulators

One of Claviculars' most distinctive sections is the Khavinson bioregulator catalog — the short-peptide compounds developed by Professor Vladimir Khavinson's St. Petersburg research group for tissue-specific regenerative research. Most vendors carry none of these. Claviculars stocks:

Cortagen, Cardiogen, Thymogen, Pinealon, Livagen, Ovagen, Pancragen, Prostamax, Testagen, Vesugen, Vilon, Cartalax, Chonluten, Crystagen, Bronchogen, and Vesilute.

For researchers working in the Khavinson framework — the short-peptide model of tissue-specific gene regulation — this is the deepest catalog on the market.

Don't Forget the Bac Water

Every reconstitution protocol needs proper bacteriostatic water. Claviculars stocks both standard Bacteriostatic Water and USP Bacteriostatic Water — a small detail, but a vendor that sells reconstitution supplies alongside their peptides signals they understand the full research workflow.

Final Take

Claviculars Peptides isn't the cheapest vendor in the space, and they don't try to be. What they offer is a serious, comprehensively organized catalog of research compounds with documented purity standards, unusually deep coverage in niche categories (Khavinson bioregulators, senolytics, triple-agonists, mitochondrial peptides), and protocol-level thinking that most peptide sites lack entirely. For researchers running multi-pathway protocols or working in less-mainstream categories, it's worth a look.

Start with their featured 5-compound core protocol if you want the curated entry point, or browse the full product catalog to explore the 143-compound range.
