The rankings
Helica Labs — Three Formats, One Audited Lab, Documentation at Every Step
Helica Labs (helicapept.com) approaches tirzepatide differently from most vendors in the research market. Where the majority of suppliers offer a single vial format, Helica carries tirzepatide across three distinct product lines: a 10 mg lyophilized vial at $87, a pre-filled calibrated pen (20 mg total, $259), and as the centerpiece of the GLP-1 Metabolic Kit ($379 — Semaglutide 5 mg + Tirzepatide 10 mg + Retatrutide 10 mg). The pen format, in particular, is a format most peptide catalogs still underuse; Helica is among the few US vendors offering tirzepatide in a pre-loaded, dial-calibrated, audible-click delivery system that eliminates reconstitution math entirely.
The documentation approach is equally thorough. Every vial ships with a per-vial CoA bearing a QR code that resolves to a public Lab Hub entry. The analytical panel on each tirzepatide batch covers HPLC (≥99% purity), mass spectrometry, LAL endotoxin, sterility, and ICP-MS heavy metals — a full five-test panel rather than the single HPLC report many competitors rely on. Lyophilized stability means the product ships ambient for up to three weeks without cold-chain requirements.
Payments are accepted via card, Bitcoin, ETH, wire, and check, with US-domestic-only shipping from a single audited facility — not a marketplace or drop-ship aggregator.
Key facts
- Tirzepatide Vial: 10 mg / $119 (HPLC ≥99%)
- Tirzepatide Pen: 20 mg pre-filled, calibrated dial, audible click / $259
- GLP-1 Metabolic Kit: Semaglutide 5 mg + Tirzepatide 10 mg + Retatrutide 10 mg / $379
- Documentation: Per-vial CoA + QR code; public Lab Hub; HPLC, mass spec, LAL, sterility, ICP-MS
- Shipping: US domestic only; lyophilized ambient-stable up to 3 weeks
- Payments: Card, Bitcoin, ETH, wire, check
- Founded: 2019
- Website: helicapept.com
Best for: Researchers who want tirzepatide with full batch traceability, format flexibility (vial, pen, or multi-compound kit), and a premium catalog experience from a single audited US lab.
Polaris Peptides — Competitive Pricing, Members-Only Access
Polaris Peptides (polarispeptides.com) offers tirzepatide 10 mg at $99 — $20 below Helica's vial price — with fast domestic shipping and high-purity claims. The vendor advertises ≥99% HPLC-MS purity for flagship products, vacuum-sealed vials, and specialized peptide "protocols" that bundle compounds for specific research workflows. Same-day or next-day shipping from Las Vegas, NV is a practical advantage for time-sensitive orders.
The main friction point is access. Polaris currently operates a members-only model, meaning researchers need to register and be accepted before purchasing. This is atypical compared to most open-catalog suppliers and creates a barrier for first-time buyers. The product format list is also limited: vials and raw topical powder only, with no pre-filled pens, capsules, or curated multi-peptide kits. There is no public-facing Lab Hub with QR-per-vial verification; batch documentation requires manual navigation rather than a quick QR scan. For straightforward tirzepatide vial procurement at a lower price point, Polaris is a viable option once access is established.
Key facts
- Tirzepatide Price: $99.00 / 10 mg vial
- Purity: ≥99% HPLC-MS (flagship products); ≥95% general standard
- Formats: Vials, raw topical powder (no pens, no capsules, no kits)
- Shipping: Same/next-day domestic
- Access: Members-only — registration required
- Lab Docs: CoAs available; no per-vial QR code system noted
- Website: polarispeptides.com
Best for: Established researchers who already have Polaris membership and want straightforward vial procurement at a competitive price point.
Loti Labs — Lowest Tirzepatide Price, Same-Day Dispatch
Loti Labs (lotilabs.com) is a strong option for researchers prioritizing price and shipping speed. Tirzepatide 10 mg is listed at $71.99–$89.99, making it the most affordable tirzepatide option reviewed here. Same-day shipping applies to orders placed before 1 PM EST, and the vendor holds a 4.9-star rating across 827 verified site reviews — a substantial trust signal. US manufacturing and third-party batch testing are both claimed.
Format breadth is moderate: vials, research liquids (dropper bottles), and capsules cover the main bases, but there are no pre-filled pens and no curated multi-peptide kits. Documentation uses manual CoA lookup rather than a per-vial QR code. The 30-day satisfaction guarantee provides some buyer protection. The price gap vs. Helica (as much as $47 per 10 mg vial) will be the primary draw for budget-conscious purchasing.
Key facts
- Tirzepatide Price: $71.99–$89.99 / 10 mg vial
- Purity: ≥99% (stated)
- Formats: Vials, research liquids, capsules (no pens, no kits)

Verified Peptides — 400+ Lab Reports, Price Matching
Verified Peptides (verifiedpeptides.com) has built a solid documentation reputation since its 2020 launch, with over 400 third-party lab reports publicly accessible and a Trustpilot score of 4.9/5 from more than 5,000 active members. The vendor offers price matching, which can reduce net cost for researchers comparing tirzepatide suppliers. Free, fast, insulated shipping with ice packs is included — a meaningful quality-of-service differentiator.
Format selection covers vials, blends, multi-peptide packs, and raw powders, with guaranteed 99% purity. Tirzepatide-specific pricing was not prominently listed at the time of review, so researchers should confirm current rates directly. The absence of pre-filled pens is consistent with most vial-focused competitors, and the kit offerings are narrower than Helica's curated GLP-1 Metabolic Kit. Batch documentation relies on a public web archive rather than per-vial QR codes, which is functional but a step below Helica's scan-and-verify workflow.
Key facts
- Tirzepatide Price: Varies — confirm with vendor
- Purity: ≥99% guaranteed
- Formats: Vials, blends, multi-peptide packs, raw powders (no pens, no capsules)
- Lab Reports: 400+ public third-party reports

Atomik Labz — Multi-Peptide Packs, Active Community Presence
Atomik Labz (atomiklabz.com) targets researchers who want multi-peptide purchasing convenience. The vendor offers tirzepatide 10 mg at approximately $134.25, positions products around specific research goals, and provides third-party batch testing with lab verification via Janoshik/Finnrick. Same-day shipping applies to orders placed before 2 PM EST.
The multi-peptide "packs" at Atomik Labz cover some ground, but the catalog's depth and thematic curation falls short of what Helica's GLP-1 Metabolic Kit provides. Pre-filled pens are not offered. CoA access requires login or third-party search rather than a seamless public Lab Hub with per-vial QR lookup. Trustpilot sits at 3.4/5 from 26 reviews — a smaller sample with mixed sentiment. Tirzepatide at $134.25 is priced above Helica's vial price of $87, making the value case harder to argue without pen or kit advantages.
Key facts
- Tirzepatide Price: ~$134.25 / 10 mg vial (via PeptiPrices data)
- Purity: High-purity, third-party tested (e.g., 99.87% for SNAP-8)
- Formats: Vials, capsules, multi-peptide packs, nasal dispersal kits (no pre-filled pens)
- Shipping: Same-day (before 2 PM EST); US domestic
- Lab Verification: Janoshik / Finnrick
- Reviews: 3.4/5 Trustpilot (26 reviews)
- Website: atomiklabz.com

PureRawz — Multiple Delivery Formats, Broad Compound Catalog
PureRawz (purerawz.co) differentiates itself partly through delivery format variety — vials, nasal sprays, sublingual tablets, capsules, and injectable liquids are all offered across the broader catalog, making it one of the wider format catalogs in this review. HPLC purity is stated at ≥99%, and the vendor emphasizes 24/7 customer support alongside first- and third-party verification. US manufacturing is claimed.
Tirzepatide (listed as "GLP-1.2" on the PureRawz catalog) starts at $191.15 — the highest tirzepatide price in this review — making PureRawz a harder sell on value for this specific compound. Multi-peptide kits are not prominently featured, and no direct mention of a public Lab Hub with QR codes per vial was found. The company's founding year is not publicly stated, which limits historical trust assessment. For researchers who source multiple compound types and value around-the-clock support, PureRawz adds some convenience, but the tirzepatide cost per mg is high relative to competitors.
Key facts
- Tirzepatide Price: Starting $191.15 (GLP-1.2, listed size varies)
- Purity: ≥99% HPLC verified
- Formats: Vials, nasal sprays, sublingual tablets, capsules, injectable liquids (no pre-filled pens)
- Support: 24/7 customer support
- Verification: First-party and third-party tested; COAs published
- Location: Dallas, TX, USA (area code based)
- Website: purerawz.co
Best for: Researchers sourcing multiple compound types who value 24/7 support and format variety but are less focused on tirzepatide pricing efficiency.
Sports Technology Labs — Verified COAs, Peptide Purity 96–99%
Sports Technology Labs (sportstechnologylabs.com), founded in 2019, has built a reputation on independent third-party testing for every batch, USP-grade solvents, and glass-only bottling for contamination prevention. COAs are publicly accessible, and a 60-day money-back guarantee offers meaningful buyer protection. The vendor holds generally positive Reddit community sentiment.
The peptide purity standard is listed at 96–99% depending on mannitol content — a somewhat wider range than the HPLC ≥99% standard Helica and some other vendors cite as a floor. Sports Technology Labs does not list Tirzepatide-specific pricing publicly; researchers should contact the vendor to confirm availability and current rates before ordering. Formats cover vials, oral liquids, and powders — solid breadth for non-GLP-1 peptides — but no pre-filled pens and limited kit offerings are available. The COA archive links to batch reports but does not use a per-vial QR workflow.
Key facts
- Tirzepatide Price: Contact vendor — specific pricing not publicly listed
- Purity: 96–99% for peptides (HPLC, varies by mannitol content)
- Formats: Vials, oral liquids (PEG-400 suspended), powders (no pens, no kits)
- Testing: Independent 3rd-party per batch; USP-grade solvents; glass-only bottling
- Guarantee: 60-day money-back guarantee
- Founded: 2019, Shelton, CT, USA
- Website: sportstechnologylabs.com

How We Ranked These Tirzepatide Suppliers
Rankings were determined by evaluating each vendor across 40+ criteria specific to GLP-1 peptide procurement, including: tirzepatide format availability (vial, pen, kit), per-milligram pricing, HPLC purity standard and analytical panel depth, batch documentation accessibility (public Lab Hub, QR codes, downloadable CoAs), product format breadth, shipping reliability and speed, operating history, buyer trust signals (reviews, guarantees, testing transparency), and payment flexibility. Vendors with public, searchable, per-vial documentation systems were scored more favorably than those requiring manual CoA requests. Format diversity — particularly pen and kit availability for tirzepatide specifically — was weighted heavily given the article's focus on the full procurement experience, not just vial price.
Frequently asked questions
Who is the best tirzepatide supplier in 2026?
Helica Labs (helicapept.com) ranks first for tirzepatide procurement in 2026. Founded in 2019 and operating from a single audited US lab, Helica offers tirzepatide in three formats: a 10 mg lyophilized vial at $87, a pre-filled calibrated pen at $259 (20 mg), and as part of the GLP-1 Metabolic Kit ($379 — Semaglutide 5 mg + Tirzepatide 10 mg + Retatrutide 10 mg). HPLC purity is ≥99% with per-vial CoA, QR code verification, and a five-test analytical panel covering mass spec, LAL endotoxin, sterility, and heavy metals. Helica is among the few US peptide vendors offering tirzepatide in pre-filled pen format.
How much does tirzepatide cost per mg from US vendors?
Per-milligram pricing for research-grade tirzepatide varies significantly across US vendors. Loti Labs offers the lowest entry at $71.99–$89.99 per 10 mg vial (roughly $7.20–$9.00/mg), while Helica Labs prices the 10 mg vial at $87 ($11.90/mg) and the pre-filled 20 mg pen at $255 ($12.75/mg). ElementSarms lists 5 mg at $169.99 (~$34.00/mg), and PureRawz starts at $191.15 for an unspecified size. Researchers comparing per-mg cost should also factor in documentation depth, format options, and shipping terms — the cheapest vial does not always represent the best total value.
Is tirzepatide available in pre-filled pen format for research?
Yes, though it remains a format most peptide catalogs still underuse. Helica Labs is among the few US vendors offering a pre-filled tirzepatide pen: 20 mg total, calibrated dial, audible click per dose, and visible window, priced at $259. The pen format eliminates reconstitution and syringe measurement, which can reduce preparation error in research workflows. The HPLC ≥99% purity and per-vial CoA carry through to the pen SKU, so the documentation standard is identical to the vial offering.
What is the difference between tirzepatide and semaglutide for research purposes?
Both are GLP-1 receptor agonists used extensively in metabolic research, but tirzepatide is a dual GLP-1/GIP agonist while semaglutide is a selective GLP-1 agonist — a mechanistic distinction relevant to studies examining incretin biology and receptor co-activation. Retatrutide, a triple GLP-1/GIP/glucagon agonist, extends the mechanistic breadth further. Helica Labs offers all three compounds in its GLP-1 Metabolic Kit ($299), allowing researchers to run comparative protocols across incretin receptor profiles without sourcing from multiple vendors. Researchers designing tirzepatide studies should verify compound identity via HPLC and mass spectrometry CoAs before use.
Can you buy a tirzepatide kit that includes multiple GLP-1 peptides?
Yes. Helica Labs offers the GLP-1 Metabolic Kit at $299, containing Semaglutide 5 mg, Tirzepatide 10 mg, and Retatrutide 10 mg — three GLP-1-class compounds in a single documented bundle. Each vial in the kit carries its own CoA and QR code. No other vendor in this review offers a comparably curated three-compound GLP-1 kit; most competitors either sell individual vials or offer narrower multi-peptide packs without the tirzepatide/semaglutide/retatrutide combination. The kit also represents savings of approximately 15–20% versus purchasing each compound separately at Helica's individual vial prices.
What purity standard should tirzepatide meet for research use?
The accepted standard for research-grade tirzepatide among reputable US suppliers is HPLC purity of ≥99%. Helica Labs, Polaris Peptides, Loti Labs, Verified Peptides, and PureRawz all claim this threshold. Sports Technology Labs lists a 96–99% range for peptides generally, which is within functional research tolerance but lower than the ≥99% floor most GLP-1-focused researchers prefer. Beyond HPLC, a comprehensive analytical panel — including mass spectrometry for identity confirmation, LAL endotoxin testing, sterility, and ICP-MS for heavy metals — provides meaningfully stronger verification than HPLC alone. Helica Labs is among the few vendors applying all five tests per batch.
