Limitless Biotech is operating, and its COAs are real but its independent third-party testing record is weak. As of October 7, 2026, it is the rebranded Limitless Life Nootropics (a Florida LLC, BBB accredited since 2020), and product pages link batch-numbered purity, sterility and endotoxin reports. But Finnrick rates it 54% on 22 independent tests (7 passed), #432 of 457 vendors, with CJC-1295 the weakest result.
Notice: Limitless Biotech's products are sold for research use only. They are not FDA-approved and not for human or animal consumption. This review covers supplier transparency only. We didn't buy or test any products, and we have no affiliate relationship with Limitless Biotech.
Limitless Biotech at a glance
- Website: limitlessbiotech.com redirects to limitlesslifenootropics.com, which now shows the "Limitless Biotech" brand (checked October 7, 2026). It's the same business, not a separate vendor. Project Biohacking reports that accounts, order history and the catalog carried over in the rebrand, and The Peptide List notes the two names "are not evidence of two independent suppliers."
- Entity and address: the BBB lists Limitless Life Nootropics, alternate name Live Limitless, LLC, at 99 S Alcaniz St Ste A, Pensacola, FL 32502, with a second location in Gulf Breeze, FL. Principal contact: Christopher Mercer. The vendor's own homepage gives only "Pensacola, FL USA."
- Track record: 7 years in business and BBB accredited since October 5, 2020, rated A+ (BBB).
- Catalog: "more than 90 research-grade peptides" across 13 categories, with pricing behind a "research access" login (homepage).
- FDA record: no warning letter found. It wasn't among the vendors that received FDA letters dated August 24, 2026.

Limitless Biotech COAs: what's published
The homepage promises "HPLC and LC-MS testing on every research batch," a "99% purity specification" and "Complete certificates of analysis for every research compound." It says every batch gets "third-party testing from certified independent laboratories," but doesn't name them (limitlesslifenootropics.com).
What you can actually check is on each product page. The BPC-157 page links 24 reports for eight batches (#1217, #1305, #1330, #1331, #1333, #1342, #1342/B and #1347), each with a separate purity, sterility and endotoxin file, hosted on Google Drive (checked October 7, 2026).
- Lot-matched: yes, by batch number and vial size. That's better than a single sample COA per product.
- Named lab: not on the product page. The Peptide List opened the batch 1305 purity report and says it was issued by TrustPointe Analytics (published September 11, 2025). We couldn't open the Drive files ourselves, so we can't confirm the lab on other batches.
- Inconsistency: the same page states "≥99% (HPLC)" in its specs and a "≥98.5% purity standard" in its header.
Sterility and endotoxin files per batch go beyond what most vendors we review publish. But these are vendor-commissioned tests. Before relying on one, check that the lab, batch and date match your vial (how to read a peptide COA).
Independent third-party testing: Finnrick results
Finnrick tests samples customers buy and submit. It still lists the vendor under its old name. As of October 7, 2026:
| Peptide | Finnrick tests | Rating |
|---|---|---|
| Retatrutide | 4 | 75% |
| Ipamorelin | 4 | 58% |
| BPC-157 | 6 | 56% |
| CJC-1295 | 8 | 20% |
| Overall | 22 (7 passed) | 54%, #432 of 457 vendors |
Finnrick says CJC-1295 and ipamorelin results were repeatedly held back by "purity misses and underfill," and that failures were "consistent ... on some lots rather than random dispersion." Its June 2026 vendor report calls CJC-1295 (0 of 8 passed) "the clearest avoid signal" and BPC-157 "the relative bright spot." Tests run from February to September 2025, so they predate the rebrand and current batches.
For context, Swiss Chems is the only vendor on our ranked list with Finnrick data (48% on 10 tests). The others have none yet (what is Finnrick).
Labeling and products
The site calls itself "a chemical supplier," not a compounding pharmacy, and says products are "for Research, Development use only" (homepage). The deductions:
- Consumer-style formats. Alongside lyophilized vials, the BPC-157 page lists BPC-157 capsules and a BPC-157 spray. Project Biohacking also lists nasal sprays and capsules for other compounds.
- GLP-1-class items. The Peptide List lists tirzepatide and semaglutide, and Finnrick has retatrutide tests. These are the products FDA has targeted (FDA peptide regulation). We cover GLP-1-class products for research use only, with no dosing content.
- Gated pricing. You can't see prices without applying for an account.
Limitless Biotech reviews and complaints: Trustpilot and Reddit
Trustpilot shows 3.4 out of 5 from 163 reviews (20 in the last 12 months), with 74% five-star and 17% one-star, as of October 7, 2026. The company replied to 77% of negative reviews. Trustpilot notes it hasn't recently invited reviews.
Recurring themes in the negative reviews:
- Vial filling. A reviewer questioned sterility and net content because the company fills vials from bulk powder in-house. The company replied that its in-house lab is sterile.
- Order problems: wrong products, shipping errors, discount issues and slow refunds.
- Impersonators. One buyer reported a scam by a fake seller. The company replied that imposter sites exist and it doesn't text customers for extra purchases. Order only through the real domain.
Positive reviews mention phone support, packaging and delivery speed.
Reddit: we couldn't open Reddit threads for this review, so we don't report Reddit sentiment.
Is Limitless Biotech legit?
Yes as a business; no as a testing record we'd rely on. It's a real, operating Florida LLC with a long BBB history and batch-linked COAs, but its 54% Finnrick rating ranks near the bottom of 457 vendors (as of October 7, 2026).
| Check | Result |
|---|---|
| Live storefront | Yes, limitlesslifenootropics.com (limitlessbiotech.com redirects) |
| Entity and address | Live Limitless, LLC, Pensacola, FL (BBB) |
| Lot-matched COAs | Yes, by batch on product pages |
| Named lab | Not on site; TrustPointe on one report per a third party |
| Finnrick | 54%, 7 of 22 passed, #432 of 457 |
| FDA warning letter | None found |
| Trustpilot | 3.4 from 163 reviews (October 7, 2026) |
| BBB | A+, accredited since 2020 |
Alternatives we list
Limitless Biotech isn't on our ranked list. If third-party testing and COAs are what you're comparing, these vendors name their labs on their own sites:
- Peptide Plugs (7.5): Freedom Diagnostics COAs, with lot numbers on product pages.
- NextGenPeps (8.8): names Janoshik and BioRegen on its COAs and publishes its business details.
- Ascension Peptides (8.1): an 85-record COA library searchable by lot. Our code AFFILIATE50OFF takes 50% off a first order (coupon); we may earn a commission.
None of these three has Finnrick results yet, so their COAs can't be cross-checked the same way. Limitless Biotech's can, and they don't hold up well.
Verdict
Limitless Biotech has more business history and more per-batch paperwork than most vendors in this market. Its independent results are the problem: 15 of 22 Finnrick tests failed, with underfill and purity misses on CJC-1295 and ipamorelin. If you're weighing it, check the Finnrick result for your compound and the batch on your vial first.
