Best TB-500 Suppliers (2026) — Ranked by Batch Testing

TB-500 prices (Oct 2026): a standalone TB-500 price was not captured this cycle; Paramount's TB-500 is sold in the Wolverine blend (BPC-157 + TB-500) — 10mg $75 · 20mg $98.60. Free shipping over $300.

For TB-500: Paramount's route to this compound is the Wolverine blend, and blends are exactly where its proof stack matters most — every lot carries an Accumark Labs COA posted on the product page, with 16 prior lots still clickable, so a buyer can inspect the certificate for the actual batch rather than a combined marketing claim. The purity refund guarantee applies the same way: if a vial fails HPLC testing at any licensed lab, Paramount refunds the purchase and reimburses the $100 testing fee. Synthesis is in-house (Irvine, CA, 12+ years) and checkout is standard cards with prices visible without an account. We reviewed Paramount in depth here.

TB-500 price (Oct 2026): 10mg $69.95. Free shipping over $150.

For TB-500: Kylo sells the standalone compound at $69.95 for 10mg — the top of the recorded market cluster ($59.95–$69.95) — and justifies the position with the broadest published panel in this set: per-lot COAs from three named laboratories (Janoshik, Freedom Diagnostics, Vanguard) covering HPLC purity, LC-MS identity, net content, heavy metals, sterility and endotoxin, posted on the product page and archived in a public COA library. It is also the payment leader here (cards and Apple Pay, same-day shipping before 2 PM PT). Multi-unit discounts (5% / 10%) and the $497 half-price lifetime membership change the math for high-volume labs.

TB-500 price (Oct 2026): not captured this cycle. (Everest's BPC-157 10mg lists at $44.99 before stacked discounts.) Free shipping over $150.

For TB-500: Everest's TB-500 price was not captured in this review cycle, so it is listed without one rather than estimated — its ranking here rests on the proof infrastructure the score already reflects. Freedom Diagnostics runs seven tests per lot (HPLC purity, LC-MS identity, net content, endotoxins, heavy metals among them), the full COA sits on the product page, and a QR code on the vial links back to the batch record — the strongest per-lot documentation pattern in this set alongside Paramount. Checkout is the trade-off: no cards, Zelle and Pay by Bank only, turned into stacked rail discounts (5% bank, 10% Zelle) elsewhere in its catalog. A 4.9★ Trustpilot rating and free returns complete the trust stack.

TB-500 price (Oct 2026): 10mg $67. Free shipping over $150.

For TB-500: BioEdge does the single most important thing right — a batch-specific COA on the product page (independent HPLC plus mass spectrometry) — and prices the 10mg vial at $67, inside the recorded market cluster and below Kylo. US lyophilization is called out explicitly against imported, relabeled vials, pack discounts up to 15% apply automatically in the cart, and same-day shipping runs before 3 PM ET. What holds the score back: payment options were not displayed on the product pages we reviewed, and the testing laboratory is not named in the published materials.

TB-500 price (Oct 2026): 5mg $49 — sold on the store as "TBX-5." 31 products; free shipping over $150.

For TB-500: two things a buyer should know. First, the naming: Vonox lists this compound as "TBX-5" rather than TB-500, so it will not surface under the standard search term — the $49 price is for the 5mg vial, against 10mg vials in the $67–69.95 range above, so compare per milligram. Second, the proof: every batch is tested by an independent laboratory (HPLC-UV for purity, LC-MS for identity) with the Certificates of Analysis published in an open COA library readable before ordering — a stronger proof habit than several larger stores show. Vonox is a registered US company (VonoxLabs LLC, Charleston, SC, public address) with products made in the USA and a 21+ age gate. The weaknesses are the same ones that hold it mid-table in the main ranking: checkout is bank transfer and Zelle only, the COAs live in a library rather than on the product page, and as a new brand it has no public reviews yet to cross-check.

Reputation (Oct 2026): Trustpilot 4.8★ from roughly 3,000 verified reviews. A TB-500 reference price was not captured this cycle.

For TB-500: Infiniwell is the reputation-led entry — its 4.8★ Trustpilot score across ~3,000 verified reviews is the deepest public track record in this set, and roundups in this niche commonly position it for oral/capsule formats rather than the lyophilized-vial catalogs the rest of this table sells. Lot-level COA documentation of the kind the top four publish was not part of its public proof stack in the materials reviewed, so its testing and COA scores are marked † and held conservatively. If published batch documentation appears, this entry gets re-scored.

Reputation & policy (Oct 2026): Trustpilot 4.6★ · 60-day money-back guarantee · private buyer Discord. A TB-500 reference price was not captured this cycle.

For TB-500: Amino Club's trust mechanism is policy rather than paperwork — the 60-day money-back guarantee is the longest in this set, backed by a 4.6★ Trustpilot rating and an active private Discord where buyers compare notes. Batch-level testing documentation was not published in the public materials reviewed for this ranking, so its proof scores are marked † and held conservatively. Amino Club is formally invited to submit its COA documentation for re-scoring — publishing the paperwork is the fastest way up this table.
