ZC Labs: strong certificates, thin review record
Written for this vendor; the sections below are computed
If you searched "zc labs reviews", the short answer is that the testing holds up and the review record barely exists yet. ZC Labs scores 7 of 10 on the rubric we apply to every vendor, read on 1 November 2026.
The certificates are the strong part. The COA portal lists 77 certificates across 26 products from two named labs, ILS Laboratories and Freedom Diagnostics, with current and archived lots side by side and nothing behind a login. We opened the ILS report for BPC-157 10 mg (COA-2026-956697, lot 001-B) and followed its access code to ILS's own portal, which showed it as a verified certificate: 99.62% purity and 10.53 mg measured on a 10 mg label. The lot currently shipping, ZC-BPC-104, has a Freedom Diagnostics report at 99.38% and 10.30 mg.
Three points are withheld. Trustpilot shows only two reviews on an unclaimed profile, so there is no independent buyer record to read. The only address is a PO box, and our rubric asks for a street address. And the homepage says seven tests run on every new batch at ILS, while the certificate for the current BPC-157 lot is a three-result Freedom Diagnostics report. The company is Zc Labs LLC with a PO box in Myrtle Beach, South Carolina; cards are accepted, and single vials were buy-one-get-one when we read the store. PeptideBenchmark scores ZC Labs low because it holds no certificates for the vendor, not because of a negative finding.

Contradiction — the vendor's claims disagree with each other or with the evidence
ContradictionHomepage
'seven tests run on every new batch at ILS Laboratories'. The certificate for the current BPC-157 lot (ZC-BPC-104) is a Freedom Diagnostics report with three results (identity, purity, net content).

Flag — read before ordering

The homepage says seven tests run 'on every new batch at ILS Laboratories', but the certificate shipping with today's BPC-157 lot is a three-result Freedom Diagnostics report, not the seven-test ILS panel. The only address is a PO box. The June ILS report names zclabs.shop, an earlier domain that no longer resolves. Ships within the US only.

Threads read via search on 1 November 2026 · not scored
No Reddit thread about ZC Labs surfaced on 1 November 2026, and Trustpilot holds two reviews. There is no independent buyer record yet in either direction.
How this was read: Google's Reddit results for "ZC Labs reddit" on 1 November 2026 — thread titles, subreddit, dates and the text visible in search. We did not read every comment, so a gist says what a thread is and what its visible text says, not what it concludes. Threads in a vendor-run or ranking-site subreddit, and listicles or coupon posts in unrelated subreddits, are labelled as such. None of this is an input to the score; the rubric reads evidence, not opinions.

Where to order
Verified partner code
10% off single vials at ZC Labs with
Affiliate; we earn a commission. Everything above was published before the partnership and not softened for it. Code terms.
On our evidence it scores 7/10. The ILS certificate we opened for BPC-157 lot 001-B verified on ILS's own portal (10.53 mg on a 10 mg label, 99.62%), 77 certificates are public, prices are open, the operator is Zc Labs LLC (PO Box 284, Myrtle Beach, SC), and cards are accepted. The three missing points are a review base (two Trustpilot reviews), a street address (PO box only), and a testing claim the current BPC-157 lot does not meet. ZC Labs is an affiliate partner of ours; the score was read before the partnership and does not depend on it.
Do ZC Labs COAs check out at the lab?
The ILS one we ran did. On 1 November 2026 the access code printed on report COA-2026-956697 opened on portal.ils-lab.com as a verified certificate for Zc Labs, lot 001-B, received 3 June and confirmed 10 June 2026. Freedom Diagnostics reports print an accession number and search code (for example ZCLa2608120180) that you can look up on the lab's own search page.
Why does PeptideBenchmark score ZC Labs so low?
On 1 November 2026 PeptideBenchmark's ZC Labs page said it holds no certificates for the vendor, and its score is built mainly from certificates it holds. The low number reflects missing data on their side rather than a failed test. We scored the certificates ZC Labs publishes, one of which we verified at the lab.
Is the buy-one-get-one real?
When we read the store on 1 November 2026 the banner offered buy one, get one free on single vials, with the free matching vial added to the cart automatically. Five- and ten-vial packs were excluded. Promotions change, so check the cart before you pay.
Where does ZC Labs ship from, and is there a guarantee?
ZC Labs ships within the US only (no international shipping), FedEx 2Day free over $199. The site offers a 30-day money-back guarantee for purity issues, wrong items or damage, with nothing to send back, one claim per customer.
How does ZC Labs score on the verification rubric?
As of 1 November 2026, ZC Labs scores 7/10 on our verification rubric and has 3.8 (2 reviews). The trust assessment — who runs it, whether a certificate can be checked with the lab, the payment rail, and what we flagged — is on our "Is ZC Labs legit?" page at /guides/is-zc-labs-legit.
Does ZC Labs publish third-party COAs?
Read 1 November 2026, logged out. A WooCommerce store with 29 listings and open sized pricing (BPC-157 10mg $27.99; TB-500 10mg $41.99; NAD+ 500mg $34.99), with a site-wide buy-one-get-one on single vials while we read it. The COA portal publishes 77 certificates across 26 products from ILS Laboratories and Freedom Diagnostics, current and archived, each tied to a lot. The ILS report for BPC-157 10mg (COA-2026-956697, lot 001-B, analysed 10 Jun 2026) reads 99.62% purity and 10.53 mg net content on a 10 mg label, and ILS's own portal returned it as a verified certificate. The current BPC-157 lot (ZC-BPC-104) has a Freedom Diagnostics report: 99.38%, 10.30 mg. Zc Labs LLC, PO Box 284, Myrtle Beach, SC 29578 in the terms. Cards, Zelle, Cash App, bank transfer and crypto accepted.
What should buyers watch for with ZC Labs?
Trustpilot has only two reviews (3.8, unclaimed profile), so there is no independent review base yet. The homepage says seven tests run 'on every new batch at ILS Laboratories', but the certificate shipping with today's BPC-157 lot is a three-result Freedom Diagnostics report, not the seven-test ILS panel. The only address is a PO box. The June ILS report names zclabs.shop, an earlier domain that no longer resolves. Ships within the US only.
What does Reddit say about ZC Labs?
No Reddit thread about ZC Labs surfaced on 1 November 2026, and Trustpilot holds two reviews. There is no independent buyer record yet in either direction. Threads read via search on 1 November 2026; none of it is an input to the score.
Is there a ZC Labs discount code?
Yes — code health gives 10% off single vials, confirmed 1 November 2026 from the partner terms. Set and saved on our affiliate dashboard at zc-labs.com on 1 Nov 2026: 10% off single vials; 5- and 10-vial packs are never discounted. Confirmed working at checkout on 1 Nov 2026. Whether it combines with the site's buy-one-get-one on single vials is unknown, so check the cart total. Our referral link (?ea_ref=health) tracks independently of the code. Same code word as Purgo Labs and several other partners, different store. It is an affiliate code: we earn a commission on orders that use it, which is disclosed here and does not affect the rubric score above.
Who runs ZC Labs, and where is it located?
Zc Labs LLC, PO Box 284, Myrtle Beach, SC 29578 (terms page); support@zc-labs.com. The June 2026 ILS report names an earlier domain, zclabs.shop, which no longer resolves. (read 1 November 2026 from the vendor's own pages).
Which lab tests ZC Labs' products?
ZC Labs names ILS Laboratories + Freedom Diagnostics. Certificates resolve on the lab's own system, so a report can be checked with the lab rather than only downloaded from the vendor. The certificate we opened, with lot, measured content and the lab lookup, is in the certificates section of this page (read 1 November 2026).
ZC Labs vs Purgo Labs — which is better?
On our published rubric ZC Labs scores 7/10 and Purgo Labs 10/10. Both are affiliate partners, so we earn a commission either way; the comparison strip on this page lists the criteria each earns that the other does not, and the same vial at both prices.
How much is BPC-157 at ZC Labs?
10mg was $27.99 on 1 November 2026 (sale; list $29.99 struck; BOGO on single vials active when read (free matching vial added automatically)). Prices move; we record what we saw and when.
