Quick take

Landro Labs describes lot-stamped vials tested by an independent lab for purity, identity and endotoxin, but it names no lab and no certificate could be read on its site. Its returns page is clear and covers failed assays, while contact details stop at email and a form.

The seven checks

Independent lab testingPartlyIndependent third-party testing is claimed for every lot, but the lab is not named and no report could be read.
Batch-specific COAsPartlyVials are described as lot-stamped, but the COAs page showed no readable reports and product pages show none; COAs are offered on request.
Identity confirmed by mass specPartlyMass spec identity is listed among the stated tests, but no mass spec result is shown.
Research-use labelingPartlyResearch-only notices are clear, but some one-line product descriptions tie compounds to physiological research areas.
Age and use confirmationYesAn entry gate asks visitors to confirm they are qualified researchers aged 21 or older.
Clear shipping and refund termsPartlyThe returns page is detailed, but shipping terms are spread across banners, the FAQ and the terms, and lost parcels are not addressed.
Business transparencyPartlyEmail, a contact form and terms are published, but no street address, phone number or legal entity.

Landro Labs is a US online store selling freeze-dried research peptides in sealed glass vials, along with bacteriostatic water. Its homepage FAQ gives Weston, Florida, as the shipping origin, and its About page is signed only by a founder named Landro.

We looked at the homepage, the catalog, the COAs page, three product pages, the About page, the returns page and the terms. The store makes detailed testing claims and has a clear returns policy, but no certificate of analysis could be read on the site when we looked.

What Landro Labs sells

The catalog page showed 34 listings when we looked, although the homepage refers to a 20-product catalog. Listings include BPC-157, TB-500 blends, Tesamorelin, Ipamorelin, CJC/Ipamorelin, GHK-Cu, KPV, Selank, Semax, SS-31, MOTS-C, NAD+, Epitalon, LL-37, HCG, two GLP class compounds and BAC water. Starting prices run from about $48 to $149 per vial.

Every product page checked describes a lyophilized powder in a sealed glass vial with a crimp seal. No sprays, capsules or pens are listed. No legal company name, founding year or street address is given.

Testing claims without readable certificates

The About page and homepage say each lot goes to an independent third-party lab for HPLC purity, mass spec identity and endotoxin screening, with a stated standard of at least 99% purity. The lab is not named anywhere we looked, and the synthesis partners are described only as GMP-aligned facilities.

The site has a dedicated COAs page with sorting options for purity and endotoxin, but its report list loads dynamically and no report, lot number, lab name or result could be read from it. The three product pages checked show no certificate, no lot number and no purity figure. The About page says COAs are available on request, and the returns page says lots ship with an independent COA.

Vials are described as lot-stamped, and the returns process asks for the lot of an affected vial, so batch matching should be possible once a report is in hand. Before ordering, ask for the report for the lot you will receive and confirm it with the issuing lab.

Labeling and purchase checks

Research-use language is consistent. Product pages state the vials are for research and laboratory use only, not for human or veterinary consumption, and not a drug, food, supplement or cosmetic. An FDA statement appears on the pages checked, and storage notes are given without amounts.

A gate on entry asks visitors to confirm they are qualified researchers aged 21 or older, and the terms repeat that requirement. Some one-line product descriptions tie compounds to physiological research areas, which goes a step beyond strict research-use labeling.

Ordering, shipping and returns

Banners advertise 2-day shipping and free shipping on orders over $49.99, while the FAQ gives 2 to 4 business days for domestic orders. The terms limit delivery to US addresses, promise tracking on every order and pass risk of loss to the buyer once the carrier accepts the parcel. Lost parcels and cold packs are not covered, and no payment methods are listed before checkout.

The returns page is the most detailed policy on the site. Claims must be raised within 14 days of delivery. Transit damage and a failed independent assay qualify for a full refund including shipping, and a wrong SKU or lot is also covered. Unopened, sealed product can be returned for any reason, less a 10% restocking fee and return shipping. Opened vials and reconstituted product are excluded. Qualifying returns get an RMA number and a prepaid label within one business day, and refunds go to the original payment method within about 3 to 5 business days.

Support runs by email and a contact form. The homepage and returns page give a Gmail address, while the terms list a domain address; no phone number is published.

Verdict: what to check before ordering

Landro Labs suits labs that want a mid-sized US catalog, a 21+ research gate and a returns policy that covers failed independent assays. It is a weaker fit for labs that need to read a named-lab certificate before buying, since no report could be viewed on the site.

Before ordering, request the COA for your lot, check that it names the lab and shows mass spec identity, and keep the 14-day claim window in mind.

Questions

Is Landro Labs legit?

Landro Labs publishes research-use terms, a 21+ gate and a detailed returns policy, and it describes lot-stamped vials tested by an independent lab. The lab is unnamed and no report could be read online, and no outside reviewer can vouch for a single order, so ask for the lot report, match its batch number to your vial and confirm it with the issuing lab.

Does Landro Labs publish COAs?

The site has a COAs page, but its report list loads dynamically and no report could be read when we looked, and the product pages checked show none. The About page says COAs are available on request, so ask support for the report tied to your lot.

What is the Landro Labs return policy?

Claims must be made within 14 days of delivery. Transit damage, wrong items and failed independent assays are covered, and unopened sealed vials can be returned less a 10% restocking fee and return shipping; opened vials cannot be returned.

Where does Landro Labs ship from?

The homepage FAQ names Weston, Florida, and the terms limit delivery to US addresses. Domestic orders are said to arrive in 2 to 4 business days, with tracking on every order.
