Peptide Labs X operates with 67 active Peptides.SO listings, establishing itself as a mid-to-large catalog research peptide supplier in the U.S. domestic market. The "Labs X" branding signals a scientific-institutional orientation — positioning the company toward laboratory researchers rather than consumer wellness audiences. With coverage spanning growth hormone secretagogues, GLP-1 receptor agonists, tissue repair compounds, longevity bioregulators, and cognitive peptides, Peptide Labs X competes in the broadly-cataloged mid-tier supplier segment.
This review examines the Peptide Labs X catalog, testing standards, pricing, and overall positioning for researchers evaluating suppliers in 2026.
Company Overview
Peptide Labs X positions itself around laboratory research standards rather than consumer wellness positioning — a distinction that matters for researchers evaluating supplier credibility. The catalog reflects systematic coverage across the major research peptide compound classes, with availability confirmed through Peptides.SO's listing tracking system.
The 67-listing catalog size places Peptide Labs X in the upper range of mid-tier domestic suppliers. The company's product mix emphasizes both the established, high-demand compound categories (GLP-1 agonists, BPC-157, CJC-1295/Ipamorelin) and extends into longevity bioregulators and neurological research compounds.
Catalog Depth and Breadth
Growth Hormone Secretagogues
The GH-axis coverage is comprehensive: CJC-1295 with DAC (5mg, $75), CJC-1295 without DAC in both 5mg ($80) and 10mg ($75) formats, Ipamorelin, GHRP-2 (nasal spray format, $40), GHRP-6 ($40), Hexarelin, Sermorelin, and Tesamorelin. MK-677 extends coverage to the oral secretagogue research space.
Multiple formats and dose sizes for CJC-1295 reflect operational sophistication in serving researchers with varied experimental protocols. The nasal spray format availability for GHRP-2 is a distinctive catalog feature not uniformly offered by competitors.
GLP-1 and Metabolic Research Compounds
Semaglutide (labeled "1G-SGT," 20mg, $69.99–$119.99) and Tirzepatide (labeled "2-TZ," $59.99–$199.99) are the primary GLP-1/GIP-class listings. Cagrilintide (CAG 10mg, $325) covers the amylin receptor agonist research space. Retatrutide (labeled "3-RT," $79.99–$219.99) — Eli Lilly's triple GLP-1R/GIPR/GCGR agonist in Phase 3 trials — is listed in multiple formats. Mazdutide, a GLP-1/glucagon receptor dual agonist, extends the metabolic research compound coverage.
5-Amino-1MQ ($349) — a NNMT (nicotinamide N-methyltransferase) inhibitor studied in metabolic biology — rounds out the metabolic research segment.
Tissue Repair and Regeneration
BPC-157 is available in multiple formats and sizes ($95–$349), reflecting demand and pricing flexibility for varied experimental scale. TB-500, the TB-500/BPC-157 combination blend, and the four-compound BPC-157/TB-500/KPV/GHK-Cu blend cover the tissue repair compound space comprehensively.
The Beauty Blend (GHK-Cu/KPV, $39.99 and $50) adds a cosmetic research dimension to the tissue repair/regeneration segment.
Longevity and Specialty Compounds
Epithalon ($133.33 standard, with 100-vial 50% off bulk option) is available for telomere biology and longevity research programs. FOXO4-DRI ($189.99) covers the senolytic peptide research space. Follistatin 344 ($155) — studied in muscle biology and myostatin inhibition research — is a notable catalog entry. MOTS-c ($135), NAD+ formulations, and Dihexa (a nootropic peptide studied in neuroplasticity and synaptic connectivity, 8mg/30 tabs, $110) extend the specialty compound catalog.
BDNF (Brain-Derived Neurotrophic Factor, 10mg, $150) is an unusual catalog entry — BDNF itself is a signaling protein rather than a research-use synthetic peptide, suggesting engagement with neurotrophin biology research tools.
Cognitive Research Compounds
Semax and Selank cover the standard neuroprotective/anxiolytic research peptide space. The Dihexa listing adds a synthetic nootropic peptide with neuroplasticity research applications beyond the standard Semax/Selank pair.
Melanocortin Peptides
Melanotan II (MT-2) and PT-141 (Bremelanotide, FDA-approved as Vyleesi) are both listed.
Ancillary Products
Bacteriostatic water, acetic acid solution, LIPO-C with B12, and Glutathione round out the ancillary compound and reconstitution support product set. The inclusion of Curcumin ($150) and Dihexa tablets reflects some expansion into oral/capsule format research compounds.
COA Standards and Testing Quality
Peptide Labs X applies third-party HPLC purity characterization and mass spectrometry identity confirmation to its product catalog. COA documentation is available per product, consistent with the testing standard of established domestic mid-tier suppliers. Researchers should request batch-specific COA documentation for precision experimental applications.

Frequently Asked Questions: Peptide Labs X
Q: What is Gonadorelin and why is it in Peptide Labs X's catalog at $75?
A: Gonadorelin is the synthetic decapeptide identical to endogenous GnRH (gonadotropin-releasing hormone) — the hypothalamic peptide that stimulates pituitary LH and FSH secretion. Research applications include studying the hypothalamic-pituitary-gonadal (HPG) axis, LH pulsatility patterns, reproductive neuroendocrinology, and fertility biology. Gonadorelin's research use is distinct from GnRH agonist analogs (like Triptorelin, Leuprolide) that cause receptor desensitization — native GnRH produces pulsatile LH/FSH release. At $75 (Gonadorelin 2mg, ~$100/mg at Peptide Labs X), pricing sits in the mid-range for this compound. See: Gonadorelin Research Profile
Q: What is LL-37, and what distinguishes it from other antimicrobial peptides in the catalog?
A: LL-37 is the mature C-terminal fragment of human cathelicidin (hCAP18), a 37-amino-acid cationic antimicrobial peptide produced by neutrophils, epithelial cells, and keratinocytes. It is one of only two human cathelicidin peptides (the other being the 29-AA LL-29/CRAMP homolog). LL-37's research applications span antimicrobial mechanism studies (membrane disruption, biofilm inhibition), innate immunity signaling, wound healing promotion, and anti-inflammatory effects in the lung epithelium. At $75 (10mg, $100/mg), Peptide Labs X offers LL-37 at a mid-premium tier — the compound requires complex synthesis and is harder to source than standard GH axis peptides. See: LL-37 Research Profile
Q: What is Epithalon's sale price at Peptide Labs X, and how does it compare to the market?
A: The Epithalon "100 VIALS AT 50 PERCENT OFF" listing at $100 (implying ~$200 pre-sale, or ~$133/mg if 0.75mg per vial) places Peptide Labs X on the higher end of platform Epithalon pricing. For comparison, platform tracking shows Epithalon ranging from ~$30-180 per vial across indexed suppliers. Researchers purchasing bulk Epithalon for extended anti-aging biology or telomerase studies should compare per-mg cost against bulk-supply alternatives. See: Epithalon Research Profile
Q: Is MK-677 (Ibutamoren) a peptide, and why is it in a peptide catalog?
A: MK-677 is a non-peptide ghrelin receptor agonist — a small molecule that mimics ghrelin's GHS-R1a receptor activation to stimulate pulsatile GH secretion. It is orally bioavailable (unlike peptide GH secretagogues). Research suppliers frequently list MK-677 alongside peptide GH secretagogues (Ipamorelin, GHRP-6, CJC-1295) because researchers studying the GH axis often want to compare oral vs. injectable GHS-R1a agonism in the same experimental program. At $140 ($187/mg), Peptide Labs X's MK-677 pricing is above the value-tier but within the range for domestic research-grade material.
Q: Is Peptide Labs X verified on Peptides.SO?
A: Peptide Labs X holds no verified badge on Peptides.SO and has limited platform rating history. Researchers should request batch-specific COA documentation (HPLC purity, mass spectrometry identity) directly from the supplier before ordering, particularly for specialty compounds like LL-37 and Gonadorelin where analytical verification is more technically demanding.
Q: What does the "Labs X" branding signal about catalog positioning?
A: The "Labs X" naming convention is common in research compound branding and typically signals scientific/laboratory-grade positioning — distinguishing the brand from consumer supplement language. The 67-listing catalog spanning peptides, SARMs, specialty compounds, and accessories reflects a mid-to-large research catalog with intentional coverage breadth. The pricing tier (mid-to-premium across tracked listings) aligns with a quality-conscious positioning rather than volume/value tier competition.
