Ascension Peptides Review: Is It Legit? COAs, Labs, FDA Record

Is Ascension Peptides legit? No FDA warning letter, and its COAs name two labs. But its address is a UPS Store mailbox, it names no owner and all sales are final.

The short version

Ascension Peptides has no FDA warning letter on record. Its product pages carry batch-numbered certificates from two named labs, Kovera Labs and MZ Biolabs, and I matched one on Kovera's own website. Against that, its address is a mailbox at a UPS Store in Kansas City, Missouri, and it names no owner. All sales are final, and Trustpilot has removed its profile. It also sells retatrutide, tirzepatide and semaglutide under code names. I checked its site, the labs, FDA, the Justice Department and Finnrick on 3 October 2026. This is a fact check, not a rating.

  • No FDA warning letter names Ascension Peptides, and it is not named in FDA's drug import alerts, as of 3 October 2026.
  • Product pages show lot-numbered COAs from Kovera Labs and MZ Biolabs. One Kovera report matched the record on the lab's own verification portal.
  • The address it lists is a UPS Store in Kansas City, Missouri, that rents mailboxes. The site names no owner or legal entity.
  • Products listed as R-10, T-10, S-5 and C-10 link to COAs for retatrutide, tirzepatide, semaglutide and cagrilintide.
  • All sales are final. Damage must be reported within 24 hours, and the return policy warns of legal action over chargebacks.

Ascension Peptides has no FDA warning letter on record, and its product pages carry batch-numbered certificates from two named labs. I matched one, a Kovera Labs report, on the lab’s own website. Against that, its address is a UPS Store mailbox in Kansas City, it names no owner, all sales are final, and Trustpilot has removed its profile.

I ran my peptide vendor checklist against ascensionpeptides.com on 3 October 2026. I used the company’s pages, the labs’ websites, FDA and Justice Department records, and Finnrick. There is no star rating or score.

Which Ascension Peptides site is real?

ascensionpeptides.com is the site the labs name. The MZ Biolabs certificate I opened gives www.ascensionpeptides.com as the client website, and Finnrick tracks the same domain. The domain was registered on 26 September 2023, according to the .com registry.

Other sites use the name. On 3 October 2026, ascensionpeptideslab.com, ascensionpeptidelabs.com and ascensionbiotech.com all called themselves Ascension Peptides in their page titles. The site ascensionpeptidelabs.com repeats the real site’s FAQ answers in near-identical words, such as the line about not supplying bacteriostatic water or acetic acid. I found nothing tying any of them to ascensionpeptides.com.

Ascension Labs, at ascensionlabs.bio, trades under a similar but different name. I found nothing tying it to Ascension Peptides either.

FDA and Justice Department records

I searched FDA’s warning-letter index for “Ascension Peptides” and “ascensionpeptides” on 3 October 2026. No letter names the company. Neither name appears in the 10 import alerts in FDA’s human-drug chapter, including Import Alert 66-41 for unapproved drugs promoted in the US. A Justice Department site search for “ascension peptides” returned no results.

These searches also return nothing for a company FDA has never examined, so they are not a certificate of legality or safety. Research peptides and US law explains what a “research use only” label does and doesn’t mean.

Does Ascension Peptides test its products?

Ascension’s COA library lists 85 records, searchable by product, batch and test date. Each product page also shows its latest certificates, with the lab, batch number and test date. The certificates name 2 labs: Kovera Labs, in Buffalo Grove, Illinois, and MZ Biolabs, in Tucson, Arizona.

I opened both certificates for the Wolverine Stack, a BPC-157 and TB-500 blend sold as 20 mg:

  • Kovera Labs, batch 08-05260628: report KVR-2026-5C72F1, certified 15 June 2026. It reports 99.473% purity by HPLC, identity by LC-MS and 22.71 mg of peptide. Endotoxin was below 0.20 EU/mL against a 0.5 EU/mL limit, with no microbial growth and heavy metals below its limits.
  • MZ Biolabs, batch 08-01260229: analysed 28 January 2026. It reports 99.97% purity by HPLC, identity confirmed by mass spectrometry, and 13.88 mg of BPC-157 plus 11.73 mg of thymosin beta-4.

The Kovera certificate carries a QR code. It led to the same report on Kovera’s own verification portal, with the same client, batch and results. A lab confirming a record on its own site is the strongest check a buyer can make.

The certificates have limits:

  • Kovera’s sterility result is a “rapid sterility screen”. The report calls it a preliminary check and says full USP 71 testing “may be required” for regulatory compliance.
  • The same sterility page gives 29 May 2026 as both the date received and the date certified, yet describes a 2-day incubation.
  • The product pages call the labs “accredited”, but neither certificate I opened names an accreditation.

How to read a peptide COA covers what to match on a certificate.

GLP-1 drugs under code names, and hCG

Some products are listed only by code. R-10, T-10, S-5 and C-10 link to MZ Biolabs certificates that name the compounds as retatrutide, tirzepatide, semaglutide and cagrilintide. The R-10 page carries no description beyond the code and “For research use only.” The other three describe the molecule without naming it. One COA panel on the C-10 page is headed “Cagrilintide”.

Semaglutide is the active ingredient in Ozempic. FDA says retatrutide and cagrilintide are not components of any approved drug. It has warned other companies that sold semaglutide, tirzepatide or retatrutide falsely labelled “for research purposes”, with dosing instructions. I found no dosing instructions on Ascension’s pages. My guides to retatrutide, tirzepatide and semaglutide cover what each one is.

Ascension also sells “HCG (5000iu)” as a research product, with MZ Biolabs certificates for two batches. hCG is a prescription drug in the US: the label for one approved brand, Novarel, is marked “Rx only”. My hCG guide covers what the approved drug is used for.

Where is Ascension Peptides located?

The contact page lists a mailing address: 1221 W. 103rd St, Unit #212, Kansas City, MO 64114. That is The UPS Store #4890, whose own page offers mailbox services at the address. Many small online sellers use a mailbox, so it proves nothing by itself. It also cannot confirm a business premises.

The site names no owner, officer or legal entity. Its footer’s “About Us” link leads nowhere, and /about-us/ returns a “page not found” error. Its terms say the site is governed by the laws of “Kansas City, KS”, across the state line from the mailbox.

Payments, shipping and returns

The payment pages disagree. The FAQ lists Visa, Discover, American Express, Apple Pay, Google Pay and ACH bank draft through LinkMoney. The shipping page lists only Visa and ACH. ACH bank payments don’t carry card chargeback rights.

The return policy warns that a customer who files a chargeback without contacting the company first may face legal action. If the company defends a chargeback successfully, it says it may charge a fee.

As of 3 October 2026, shipping is a flat $15 by UPS or USPS, to US addresses only. The shipping page says delivery takes 2 to 5 business days, while the FAQ says UPS Ground only, in 5 to 7.

All sales are final, with no returns, exchanges or refunds “for any reason”. The return policy gives 24 hours to report a damaged or defective order, and replaces an order only when the company shipped the wrong item. The FAQ gives 48 hours and promises “a replacement or a refund as needed” for a damaged or incorrect order. Loss or damage in transit is the buyer’s risk unless Route shipping protection was bought at checkout.

As of 3 October 2026, a 10 mg vial of BPC-157 was listed at $49.00, shown as reduced from $74.99.

Dosing and disease claims

The site uses research-only wording throughout. Its footer says “Products are Not for Human consumption of any kind”, and buyers must be 21 or older. Its terms make buyers warrant they are “affiliated with a laboratory, institution, university or other research based facility”. They also describe the products as for “laboratory/hobbyist research use only”. The contact page warns that questions about “methods of consumption, dosages, etc.” will go unanswered. I found no dosing instructions or disease claims on the pages I checked.

Independent reviews

Independent data on Ascension is thin. Finnrick lists the company but has published no tests of its products. Trustpilot’s page for ascensionpeptides.com reads “This profile has been removed”, saying the business “goes against our guidelines”. It does not say which guideline. A search of BBB’s directory for “Ascension Peptides” returned no results.

Ascension’s FAQ describes a partner programme with a commission structure. A review page carrying an Ascension discount code may be paid per sale, so look for a disclosure before trusting it.

What is the best peptide company to buy from?

I don’t rank vendors or name a best one, because no regulator checks what research peptide sellers ship. Five checks separate a seller you can verify from one you can’t:

  1. A certificate the lab confirms. Look the batch up on the testing lab’s own site, as with the Kovera report above.
  2. An identity test. Mass spectrometry confirms the molecule; a purity figure alone does not.
  3. Independent tests. Results from a tester such as Finnrick, not only the seller’s own certificates.
  4. A clean FDA record. Search FDA’s warning letters for the seller’s name and domain.
  5. A named owner, a real address and card payment.

My vendor checklist has all 14 checks, and the vendor list applies them to other sellers.

Common questions

Is Ascension Peptides legit?

Ascension Peptides has no FDA warning letter on record as of 3 October 2026, and its product pages carry lot-numbered certificates from two named labs. I matched one of them on Kovera Labs' own verification portal. Against that, its address is a UPS Store mailbox and it names no owner. All sales are final, and Trustpilot has removed its profile, saying the business goes against its guidelines. The scorecard on this page sources each point.

Is ascensionpeptides.com the real Ascension Peptides?

It is the site the labs name. The MZ Biolabs certificate I opened gives www.ascensionpeptides.com as the client website, and Finnrick tracks the same domain. Other sites also call themselves Ascension Peptides, including ascensionpeptideslab.com, ascensionpeptidelabs.com and ascensionbiotech.com. I found nothing tying them to ascensionpeptides.com. Ascension Labs, at ascensionlabs.bio, trades under a different name.

What is the Ascension Peptides return policy?

All sales are final, and the company says it accepts no returns, exchanges or refunds for any reason. Its return policy asks you to report a damaged or defective order within 24 hours. It offers a replacement only when it shipped the wrong item. Its FAQ gives 48 hours and promises a replacement or refund for a damaged or incorrect order. Damage or loss in transit is the buyer's risk unless Route shipping protection was bought at checkout.

Does Ascension Peptides sell GLP-1 drugs like Ozempic?

Yes, under code names. Products listed as R-10, T-10, S-5 and C-10 link to MZ Biolabs certificates that name the compounds as retatrutide, tirzepatide, semaglutide and cagrilintide. Semaglutide is the active ingredient in Ozempic. FDA says retatrutide and cagrilintide are not components of any approved drug. It has warned other companies that sold semaglutide, tirzepatide or retatrutide with a research-only label and dosing instructions.

Does Peptide Decode recommend Ascension Peptides?

No. This page does not rate, rank or recommend Ascension Peptides or any other vendor, and Peptide Decode has no partner or affiliate deal with it. It reports sourced facts against a published checklist so you can judge the company yourself.
