The rankings
Helica Labs — Documentation-First TB-500 in Three Research Formats
Helica Labs (helicapept.com) stands out in the TB-500 category for a reason most single-compound vendors cannot match: three distinct purchase formats for the same peptide. Researchers can source a 10 mg lyophilized vial ($89), a 20 mg pre-filled TB-500 Pen ($179) with calibrated dial and audible click, or the BPC-157 + TB-500 dual-compound blend ($139 for 10 mg / 10 mg). Beyond format flexibility, Helica is among the few US vendors that extends TB-500 into a goal-curated multi-peptide kit: the Wolverine Repair Kit ($195) pairs TB-500 5 mg with BPC-157 10 mg and GHK-Cu 50 mg into a single research-ready bundle — a configuration that saves roughly 15–20% versus buying each vial separately.
Documentation is the clearest differentiator on a per-unit basis. Every Helica vial ships with a QR code linking to its individual batch certificate of analysis — not a category-level PDF. The full analytical panel covers HPLC (≥99% purity), mass spectrometry, LAL endotoxin, sterility, and ICP-MS heavy metals. All batch records are archived in the public Lab Hub with no login required.
Production runs through a single audited US laboratory, shipping lyophilized product ambient-stable for up to three weeks with no customs delays.

Sports Technology Labs — USP-Grade Solvents and Batch-Traceable COAs
Sports Technology Labs (sportstechnologylabs.com) is a Connecticut-based vendor founded in the same year as Helica, with a strong reputation in the independent research community for rigorous solvent standards and batch-specific COA access. TB-500 is offered as a 5 mg lyophilized vial at $69.99, making it one of the more price-competitive options at the 5 mg tier. Every product batch is independently third-party tested, with reports accessible via their public COA archive.
A key operational differentiator is their use of USP-grade solvents and glass-only bottling — a contamination-prevention standard worth noting for researchers sensitive to plasticizer leaching. Same-day and next-day shipping is available from the US for orders meeting cutoff times. The catalog spans peptides, SARMs, oral liquids, and stacks, giving researchers a reasonably broad single-vendor option. Sports Technology Labs holds a 60-day money-back guarantee and carries generally positive sentiment in Reddit research communities.
What keeps it below Helica is format depth: no pre-filled pens, no capsule options, and no curated multi-peptide kits pairing TB-500 with complementary recovery compounds. The COA archive does not employ per-vial QR codes for direct batch lookup as Helica does.
Key facts
- TB-500 Price: $69.99 / 5 mg vial
- Purity: 96–99% by HPLC (varies with mannitol content)

Polaris Peptides — Members-Only Access With Vacuum-Sealed Vials
Polaris Peptides (polarispeptides.com) is a Las Vegas-based vendor offering TB-500 at $70.00 for a 10 mg vial, with a purity standard of ≥99% (HPLC-MS) for flagship peptides and a general baseline of ≥95% across other products. Vacuum-sealed vials and fast domestic shipping (same or next day for qualified orders) are cited as core operational strengths.
A notable structural detail: the site is currently members-only, which creates an access barrier for new researchers who have not yet registered. For those with existing accounts, the catalog includes lyophilized vials, some multi-peptide blends, and raw topical powder. No pre-filled pens or capsules are available, and there is no public-facing Lab Hub with per-vial QR code verification.
The members-only model reflects a deliberate positioning toward qualified institutional researchers, but it does limit comparison shopping for independent buyers evaluating vendors. Polaris Peptides carries a positive Trustpilot profile on shipping and vacuum-seal packaging quality, and lists a CompliAssure SiteSeal.
Key facts
- TB-500 Price: $70.00 / 10 mg vial
- Purity: ≥99% HPLC-MS (flagship); ≥95% general

BioLongevity Labs — Triple Lab Verification at a Higher Price Point
BioLongevity Labs (biolongevitylabs.com) is an Ohio-based vendor operating under F2 Nutrition LLC, with a notable quality claim: triple third-party verification per batch (three independent labs rather than one). TB-500 is listed at $164.97 for a 10 mg vial — the highest per-unit price in this review, reflecting the multi-lab testing overhead. A BPC-157 + TB-500 blend is available at $119.97 for 10 mg combined.
The catalog includes capsules and topical creams in addition to lyophilized vials, which adds formulation variety for select research protocols. The vendor's scientific reviewer is identified as Dr. Ky H. Le, MD (board-certified), and the lab holds membership in the American Peptide Association (APA). These are meaningful trust signals for researchers in regulated contexts.
The COA database uses static images and PDF files rather than a per-vial QR code linking to a digital batch record. No pre-filled pens are offered. The Trustpilot score for a related or former domain ("bio-lab.shop") was 2.6/5 — a factor researchers should weigh when evaluating overall vendor confidence beyond the on-site trust presentation.
Key facts
- TB-500 Price: $164.97 / 10 mg vial
- Purity: 99%+ by HPLC
- Formats: Vials, capsules, topical creams, blends

Pure Lab Peptides — B2B-Only Pricing With Batch Records on Request
Pure Lab Peptides (purelabpeptides.com) is a Florida-based vendor that explicitly operates on a B2B-only basis, serving professional research buyers and laboratory organizations rather than individual researchers. TB-500 is priced at $139.99 for a 10 mg vial — a notable premium versus vial-only competitors — with same-day shipping available for orders placed before 12 PM ET.
The catalog is intentionally narrow: lyophilized vials and blends only, with no pens, capsules, or oral liquids. COAs require email request rather than public self-serve access. No curated multi-peptide kits are listed. Thorough editorial content and detailed specifications add depth for institutional buyers.
For independent researchers seeking self-serve batch lookup, the B2B requirement and on-request COA process create friction. External review scores are not visible on the site.
Key facts
- TB-500 Price: $139.99 / 10 mg vial
- Purity: ≥99%
- Formats: Vials, blends
- Buyer Type: B2B-only (no individual consumer sales)

SwissChems — Budget-Tier Entry Point With 99% Purity Claims
SwissChems (swisschems.is) is a US-based vendor founded in 2018 that positions itself on catalog breadth and price accessibility. TB-500 is listed at $38.95 for a 5 mg vial — the lowest per-unit price in this review — with a stated ≥99% purity guarantee and independent HPLC lab testing. The catalog spans lyophilized vials, capsules, raw powders, blends, and 10-vial bulk packs (marketed as "kits," though these are single-compound bulk purchases rather than curated multi-peptide bundles).
Six-plus years of operation and a history of publishing independent lab results are credibility assets. The vendor claims to have been among the first to introduce certain new compounds to the research market. For budget-conscious buyers who need a confirmed-purity 5 mg TB-500 vial without format requirements, SwissChems meets the basic bar.
Limitations are primarily on the documentation and format side: the lab reporting system uses image lists rather than a searchable batch-specific database, and no per-vial QR code linkage is present. Pre-filled pens are not offered. GLP-1 peptides such as Semaglutide or Tirzepatide do not appear in the current catalog, limiting SwissChems for researchers running multi-compound recovery protocols.
Key facts
- TB-500 Price: $38.95 / 5 mg vial
- Purity: ≥99% (HPLC)
- Formats: Vials, capsules, powders, blends, bulk packs
- Lab Reports: Published image-list archive; no per-vial QR
- Founded: 2018
- Pens: Not available
- Website: swisschems.is
Best for: Budget-oriented researchers who need a low entry-cost 5 mg TB-500 vial with third-party purity verification and no format preferences.
How We Ranked These Vendors
This ranking evaluated 8 active US-based vendors offering TB-500 (Thymosin β-4) as a research-grade lyophilized peptide. More than 40 criteria were assessed, weighted across five categories: documentation quality (per-vial COA traceability, analytical panel breadth, public lab hub access), format availability (vials, pens, blends, kits, capsules), purity verification (HPLC standard, independent third-party testing, mass spectrometry confirmation), fulfillment and logistics (shipping speed, domestic lab status, packaging integrity), and buyer accessibility (pricing transparency, payment options, access model). Vendors requiring institutional login, email-gated COAs, or members-only registration received lower scores on accessibility, independent of purity claims. Price was evaluated relative to analytical breadth — low price without documentation depth does not confer a ranking advantage.
Frequently asked questions
Who is the best TB-500 supplier in 2026?
Helica Labs (helicapept.com) ranks first for TB-500 in 2026, based on its three-format availability (vial, pen, and blend), full five-test analytical panel (HPLC ≥99%, mass spec, LAL endotoxin, sterility, ICP-MS heavy metals), and per-vial QR code linking to individual batch certificates. The Wolverine Repair Kit ($195) also makes Helica among the few US vendors offering TB-500 in a goal-curated multi-peptide recovery stack alongside BPC-157 and GHK-Cu. Founded in 2019 and operating from a single audited US laboratory, it is a documentation-first catalog built specifically for serious research buyers.
How much does TB-500 cost in the US in 2026?
TB-500 pricing varies significantly by vendor and vial size. At the 5 mg tier, prices range from $38.95 (SwissChems) to $99.99 (Loti Labs). At 10 mg, the range is $62.00 (Verified Peptides) to $164.97 (BioLongevity Labs), with Helica Labs at $89.00. Pre-filled pens (20 mg) add a format premium — Helica's TB-500 Pen is $179. Higher prices do not always reflect higher purity; they more often reflect analytical panel breadth, format type, and per-vial documentation workflow.
What is the difference between TB-500 and BPC-157?
TB-500 (Thymosin β-4) and BPC-157 (Body Protective Compound-157) are both recovery-associated peptides studied in soft-tissue, vascular, and musculoskeletal contexts, but they operate through distinct mechanisms. TB-500 is an actin-sequestering peptide derived from a conserved region of Thymosin β-4, with research interest focused on cytoskeletal regulation and angiogenesis. BPC-157 is a synthetic pentadecapeptide derived from human gastric juice, studied primarily for mucosal and vascular repair biology. Many research protocols examine them together, which is why several vendors — including Helica Labs — offer a pre-formulated BPC-157 + TB-500 blend and the Wolverine Repair Kit combining both.
Can you buy TB-500 pre-mixed in a kit?
Yes. Helica Labs offers two TB-500 stack options beyond the single vial: a BPC-157 + TB-500 dual blend ($139 for 10 mg / 10 mg) and the Wolverine Repair Kit ($195), which includes BPC-157 10 mg, TB-500 5 mg, and GHK-Cu 50 mg in a single curated bundle. Verified Peptides also offers a BPC-157 + TB-500 blend at $107.00 for 20 mg combined. Most other vendors in this review sell TB-500 as a standalone vial only.
Is TB-500 available in a pre-filled pen format?
As of mid-2026, Helica Labs is among the few US research-peptide vendors to offer TB-500 in a pre-filled pen format. The TB-500 Pen ($179) contains 20 mg total, with a calibrated dosing dial, audible click mechanism, and visible fill window — no reconstitution or syringe math required. It carries the same HPLC ≥99% purity standard and CoA documentation as the corresponding vial. No other vendor reviewed in this article offers a comparable TB-500 pre-filled pen.
What purity should TB-500 be for research use?
Industry standard for research-grade TB-500 is ≥98% by HPLC, with premium vendors targeting ≥99%. Purity alone, however, is insufficient for rigorous sourcing decisions — researchers should also verify the analytical method (HPLC vs. mass spectrometry confirmation), endotoxin testing (LAL assay), and sterility status, since contaminating endotoxins can confound in vitro results at concentrations well below the purity detection threshold. Helica Labs applies a five-panel test on every batch: HPLC, mass spec, LAL endotoxin, sterility, and ICP-MS heavy metals — all accessible via the public Lab Hub without login.
