Quick take
True Peptides has detailed shipping, refund and research-use policies and says each vial's lot number matches a batch COA, but it names no testing lab and showed no reports online when we looked. Its own documents also disagree on how certificates reach buyers, the purity threshold and dispatch times, and refunds default to store credit.
The seven checks
| Independent lab testing | Partly | The site claims independent testing on every lot but never names the lab, and no report could be viewed online. |
|---|---|---|
| Batch-specific COAs | Partly | The FAQ says a lot-matched COA ships in each package, but the online certificate page showed no reports and product pages link none. |
| Identity confirmed by mass spec | Partly | Mass spec is listed as a method and a spectrum is said to ship with orders, but no mass spec results are shown online. |
| Research-use labeling | Partly | Research-use notices are prominent, but some product descriptions summarize research findings and make a safety-related statement. |
| Age and use confirmation | Partly | A 21+ rule appears in the site banner, terms and research-use policy, but no entry gate or checkout checkbox was seen. |
| Clear shipping and refund terms | Yes | Shipping and refund policies set carriers, cutoffs, 48-hour claim windows and lost-parcel rules, with recent update dates. |
| Business transparency | Partly | Terms of sale are published, but contact is by form only, no address is given and the terms name True Labs LLC. |
True Peptides is a US research peptide store that describes itself as a laboratory chemical supplier, not a compounding pharmacy. It sells 25 catalog listings of freeze-dried peptides and blends, plus bacteriostatic water, and ships only to US addresses.
The site makes strong testing claims, including independent testing on every lot and HPLC plus mass spec, but names no lab and showed no reports online when we looked. This review covers what the store's own documents say about certificates, how it labels its products, and what its shipping and refund terms promise.
What True Peptides Sells and How the Catalog Is Organized
The catalog lists 25 items sorted into five research categories, including growth hormone, metabolic and neuro research. Most products come in one or two vial sizes, from 5 mg to 100 mg, and several are blends such as KLOW and a BPC-157 plus TB-500 combination. Starting prices run from about $12 for bacteriostatic water to about $124 for the KLOW blend.
At the time of review, 20 listings were in stock and five were on backorder, including BPC-157. Product pages list each compound's CAS number, molecular formula and molecular weight, along with storage temperatures. No founding year, owner or city is given; the site says only that the company is based in the USA.
Testing and Certificates: Strong Claims, Little Online Proof
True Peptides says every lot is tested independently. Product pages state purity above 99% by HPLC and list HPLC and mass spec as the methods, and the About page adds sterility and residual solvent testing. None of these pages names the lab that does the work.
The store's documents describe how certificates are supposed to reach buyers, but they do not agree:
- The FAQ says each vial label carries a lot number that matches a dated COA, and that the COA, HPLC chromatogram, mass spectrum and safety data sheet are sealed in the package.
- The research-use policy says a COA is available on each product page and included with orders on request.
- The product pages seen link only to a general certificate page, and that page showed a loading message with no reports when we looked.
The FAQ also cites a purity acceptance threshold of 95% or higher, below the 99% figure on product pages. Until reports can be viewed, the testing claims cannot be checked from the public site.
Research-Use Labeling and Purchase Checks
Research-use-only notices are prominent. A banner on every page says products are not for human consumption and that buyers must be 21 or older, and the footer adds FDA and not-a-pharmacy disclaimers. A separate research-use policy, updated October 22, 2026, sets out who may buy and which uses are prohibited, and the contact page says questions about human use will go unanswered and related orders will be declined.
Some product descriptions go further than plain specifications. The BPC-157 page, for example, summarizes published findings and makes a safety-related statement. That content falls short of strict research-use labeling, so labeling is marked partial here. The 21+ rule and research acknowledgment are made by placing an order; no entry gate or checkout checkbox was seen.
Ordering, Shipping and Handling in Transit
The site lists cards, Apple Pay, Zelle, ACH and cryptocurrency, including Bitcoin and USDT. The shipping policy says weekday orders placed before 4 p.m. Pacific ship the same day through USPS, with standard (three to five business days), express (one to three) and overnight options. Standard shipping is included on orders of $150 or more.
Orders go only to US addresses and territories, with no international, freight forwarder or military addresses. Parcels are packed with insulation and cushioning in plain outer packaging, but no cold packs are mentioned. The FAQ separately says shipping is at ambient temperature with dispatch in one to three business days, which differs from the same-day promise, so ask support which applies.
Refunds, Lost Parcels and Support
The refund policy, updated November 1, 2026, treats sales as final once an order ships. Orders can be cancelled until a shipping label is created. Damaged, defective or wrong items must be reported through the contact form within 48 hours of delivery with photos, and the store will replace or refund at its discretion without asking for a return.
Lost parcels are handled in two ways. With the optional shipping protection, a package with no tracking movement for seven business days can be reshipped or refunded. Without it, the store files the carrier claim and passes on whatever the carrier pays. Parcels marked delivered but not received must be reported within 48 hours.
Approved refunds are paid as store credit by default. A card refund is possible on request for a fee of $35 or 10%, whichever is greater, and crypto, Zelle and ACH payments are refunded as credit only. Support is by contact form only. No email, phone or address is published, and the terms name True Labs LLC rather than True Peptides.
Verdict: Clear Policies, Unverified Paperwork
True Peptides suits US labs that value fast domestic dispatch and written claim rules, and that are comfortable requesting documents directly. Its policies are detailed, but its testing paperwork is not visible online and its documents contradict each other on key points.
Before ordering, check:
- that a COA for your exact lot is available, and which lab issued it
- that the report shows mass spec results, not only HPLC purity
- the lot number on the vial against the report
- how a refund would be paid if something goes wrong

Questions
Is True Peptides legit?
True Peptides publishes detailed shipping, refund and research-use policies and says each vial carries a lot number matched to a COA, but it names no testing lab and shows no reports online. No outside reviewer can vouch for a single order, so buyers should match the lot number on the vial to the report and confirm the report with the issuing lab.
Who tests True Peptides products?
The site says lots are tested by independent US labs using HPLC and mass spec, but it does not name the lab. Ask support which lab issued the report for your lot before ordering.
Where are the True Peptides COAs?
The FAQ says COAs ship sealed in each package, while the research-use policy says they are on product pages or sent on request. The online certificate page showed no reports when we looked.
What is the True Peptides refund policy?
Sales are final after shipping, but damaged, defective or wrong items reported within 48 hours with photos are replaced or refunded. Refunds are paid as store credit unless you accept a card refund fee of $35 or 10%, whichever is greater.
Does True Peptides ship internationally?
No. Orders go only to US addresses and territories by USPS, with standard, express and overnight options.
