Catalog Breadth: 75+ Listings Across 4 Research Categories

Polaris Peptides organizes its catalog into four primary research categories: GLP-1 & GIP Analogues, Other Peptides, Research Supplies, and Topical Peptides. This structure reflects both the research priorities driving current peptide demand and a deliberate effort to serve multi-category researchers from a single supplier.

Growth Hormone Secretagogue Segment

The GH secretagogue lineup at Polaris Peptides covers the standard GHRH and GHRP analogue stack that most GH-axis researchers require. Available compounds include:

• •CJC-1295 (No DAC) — GHRH analogue; 5mg units priced at $60
• •Ipamorelin — selective GHRP; available solo and in a blended Ipamorelin/CJC-1295 formulation at $50
• •Sermorelin — shorter-acting GHRH analogue; $75 per unit
• •Hexarelin — high-potency GHRP with prolactin and cortisol activity
• •GHRP-2 and GHRP-6 — first-generation GHRPs with distinct appetite-modulating profiles
• •Tesamorelin — FDA-approved GHRH analogue (Egrifta); $65 per unit
• •TESAMORELIN/IPAMORELIN Blend — $50

For researchers working on GH pulse pattern modification, IGF-1 axis biology, or comparative GHRP receptor binding studies, Polaris provides full coverage without requiring multiple suppliers.

GLP-1 & GIP Analogues — 22 Listings

Polaris Peptides carries a strong GLP-1 class segment — one of the most active research areas in metabolic science. The lineup includes:

• •Semaglutide — available in multiple dose formats; $30 (entry) to $175 (bulk)
• •Tirzepatide — GLP-1/GIP dual agonist; $55 (small format) to $360 (large format)
• •Retatrutide (LY3437943) — triple agonist (GLP-1/GIP/glucagon); $70 to $320 across five SKUs
• •Cagrilintide — amylin/GLP-1 combination research compound; $75 to $149 across four SKUs
• •Survodutide — $75
• •Mazdutide — $110
• •Setmelanotide — $60

The Tirzepatide and Retatrutide multi-SKU depth suggests Polaris actively tracks demand-driven volume tiers rather than stocking a single format per compound. For researchers acquiring bulk quantities for extended studies, this pricing ladder provides meaningful cost control.

Tissue Repair Peptides

Polaris carries the established tissue repair stack:

• •BPC-157 — available in four price tiers ($89–$125), suggesting different lot sizes or purity grades
• •TB-500 Fragment (17-23) — $80 per 10mg unit
• •KPV — anti-inflammatory tripeptide; $55
• •Blended combinations — BPC-157/TB-500/KPV/GHK-Cu multi-peptide blends ($35–$80), including a "Beauty Blend" (GHK-Cu/KPV) at $50

The multi-peptide blends are a differentiating feature. Pre-mixed combination products reduce researcher preparation time and can improve consistency across experimental protocols that require multiple compound administration.

Longevity, Cognitive, and Specialty Compounds

Beyond the core research categories, Polaris covers several high-interest specialty segments:

Longevity/Anti-Aging:

• •Epithalon — $45 to $125 across two units
• •Thymosin Alpha-1 — $75 per 10mg
• •Thymulin — $40 to $185
• •MOTS-c — mitochondrial-derived peptide; $55
• •SS-31 — cardioprotective mitochondrial peptide; $129
• •NAD+ — $90
• •GHK-Cu (injectable and topical forms)

Cognitive Research:

• •Semax — neuroprotective ACTH analogue; $50
• •Selank — anxiolytic nootropic; $50
• •Dihexa — NGF potentiator studied in memory models
• •PE-22-28 — antidepressant peptide analogue; $45
• •DSIP (Delta Sleep-Inducing Peptide) — $40

Melanocortin:

• •Melanotan I — $45–$50 per 10mg
• •PT-141 (Bremelanotide) — FDA-approved for HSDD; $40–$50
• •AOD-9604 — GH fragment; $40

Other Notable:

• •IGF-1 LR3 — $85
• •FOXO4-DRI — senolytic peptide; $250 per mg
• •PNC-27 — pro-apoptotic peptide; $150 per 30mg
• •LL-37 — antimicrobial peptide; $125 per 10mg

Topical Peptides (3 listings):

• •AHK-Cu — 1g raw topical format; $45
• •GHK-Cu Raw Powder — 1g topical; $30
• •SNAP-8 — 10mg; $50

Research Supplies (7 listings):

HPLC-grade solvents and synthesis reagents including Acetonitrile ($500), Ammonium Acetate ($475), TFA ($825), PyBOP ($450), HATU ($700–$800), and consumable lab supplies. This is an uncommon category for peptide suppliers — useful for research labs that prefer to consolidate procurement.

Quality Standards: COA, HPLC Testing, and Purity

Polaris Peptides states that all catalog compounds undergo third-party independent analytical testing, with HPLC (high-performance liquid chromatography) and mass spectrometry used for purity verification. Certificate of Analysis (COA) documentation is made available per product.

Third-party testing is the baseline quality standard for credible research peptide suppliers. Researchers should verify that COAs are:

• •Issued by a named independent laboratory (not the supplier's internal lab)
• •Specific to the lot number of the product received
• •Including both HPLC purity percentage and mass spec identity confirmation

Polaris Peptides has a testing score of 0 on Peptides.SO's formal verification system at time of publication — meaning the supplier has not yet undergone Peptides.SO's structured documentation review. Researchers relying on COA data should request current lot documentation directly from the supplier prior to procurement.

Pricing and Value Analysis

Polaris Peptides pricing sits in the mid-range for US domestic suppliers, with entry points that are competitive on standard research peptides and premium pricing on specialty compounds that reflect sourcing difficulty.

Representative Price Points:

The BPC-157 multi-SKU range ($89–$125) may reflect different lot sizes rather than inconsistent pricing. Researchers should confirm unit quantities when comparing across the four available listings.

Semaglutide at $30 for an entry format is at the lower end of the US supplier market, which is notable given domestic sourcing overhead. Tirzepatide at $55 for a small format is similarly accessible, though bulk formats at $360 are consistent with market rates for this compound.

The FOXO4-DRI listing at $250 per mg reflects the significantly higher synthesis cost for this longer, more complex senolytic peptide — typical of the market.

Ordering and Shipping

Polaris Peptides offers US domestic shipping with tracking. Specific carrier information and estimated transit times were not available in our current database snapshot. The company's payment methods data was not populated in our index at time of publication — researchers should confirm accepted payment options directly with the supplier.

Polaris Peptides does not publish a listed minimum order requirement. The entry-level price points (AOD-9604 at $40, PT-141 at $40, Thymulin at $40) suggest accessible low-quantity purchase options suitable for researchers acquiring compounds for initial characterization studies.

• •No payment method data — researchers should confirm directly before ordering
• •Location listed as Unknown — physical location not publicly disclosed, which limits institutional procurement vetting
• •No discount codes currently active — no savings mechanism for repeat or bulk orders beyond volume SKUs
• •No customer reviews on Peptides.SO — no aggregated user feedback available at time of review

Verdict: A Broad-Catalog US Supplier With Notable GLP-1 Depth

Polaris Peptides occupies a clear position in the domestic US research peptide market: a broad-catalog supplier with meaningful depth across GH secretagogues, GLP-1/GIP analogues, tissue repair peptides, longevity compounds, and cognitive research peptides. The 75+ listing count places it among the larger catalog suppliers tracked on Peptides.SO.

The GLP-1 segment is a standout — 22 listings including multi-format Semaglutide, Tirzepatide, Retatrutide, and Cagrilintide is among the broader GLP-1 coverage we've catalogued in the US domestic market. Researchers working in metabolic disease, obesity biology, or GLP-1 receptor pharmacology will find most compounds of interest in one place.

The combination peptide blends (BPC-157/TB-500/KPV/GHK-Cu) represent a practical feature for tissue repair researchers who prefer pre-formulated stacks over individual compound preparation. This is a differentiating offering that not all suppliers match.

The primary gap is formal third-party verification through Peptides.SO's COA review process. Researchers for whom documented purity chain-of-custody is a procurement requirement should request current lot COAs directly from Polaris Peptides before placing orders.

For independent researchers seeking a US-based supplier with catalog breadth, competitive entry pricing on GLP-1 analogues, and specialty compound availability in one location, Polaris Peptides is a catalog worth evaluating.
