Ascension Peptides Review: Kovera and MZ Biolabs COAs, 21+ Gate, Strict Return Terms

Ascension Peptides is a US-only online store for research peptides, run from a mailing address in Kansas City, Missouri, with phone and email support during weekday business hours. The catalog lists about 42 items, most of them single compounds in 3 mL vials, alongside a handful of multi-compound blends sold under brand names.

What sets the store apart is the depth of its paperwork. Product pages list lot-numbered certificates from two named outside labs, and the reports we looked at include identity testing by LC-MS as well as HPLC purity. This review covers what those reports show, how the site handles research-use labeling and age checks, and what its strict shipping and return terms mean for a buyer.

Who Ascension Peptides Is and What the Catalog Covers

The store presents itself as a supplier of purified research peptides for in-vitro work. It lists about 42 products, with prices on the first catalog page running from about $45 to $120 per vial. Single compounds make up most of the range, including BPC-157, Semax, Epithalon, DSIP, ARA-290 and two sizes of GHK-Cu.

Product pages describe each item as a synthetic peptide and show the vial size and price per vial. The store does not sell diluents or syringes, and the FAQ says so directly. A wholesale application page is offered for distributors.

The About Us link in the footer does not lead anywhere, so background such as a founding year is not stated. Contact details and a mailing address sit on the contact page instead.

Testing and Certificates: Kovera Labs and MZ Biolabs Reports

Each product page carries a short table of certificates, with the testing lab, a lot number and a test date for each entry. The BPC-157 page, for example, lists two Kovera Labs reports dated July and October 2026 and an MZ Biolabs report from March 2026. A separate COA library says it holds 122 records that can be searched by product, lot and date.

The reports are PDFs that name Ascension Peptides as the client. A Kovera Labs report for one Semax lot showed:

• HPLC purity of 99.886% against a specification of more than 98%
• An LC-MS identity result marked as a pass
• Net content of 11.23 mg for a vial labeled 10 mg
• Endotoxin and heavy-metal results below the stated limits, plus a two-day sterility screen

An earlier MZ Biolabs report for Semax went further on identity, listing an expected monoisotopic mass of 813.35 Da against a measured 813.41 Da, along with 99.75% HPLC purity and 10.12 mg per vial. The Kovera report states the identity result without the masses, so buyers who want the numbers may need to check the MZ Biolabs entries or ask support.

Research-Use Labeling and the 21+ Entry Gate

A pop-up asks visitors to confirm they are 21 or older before browsing, and declining sends them off the site. The terms repeat the 21+ rule and ask buyers to warrant a connection to a laboratory, university or research facility, with a note that further verification may be requested.

Research-use-only notices appear on product pages, in the footer and in the terms. The FAQ and contact page both say questions about personal use will not be answered, and no dosing material was seen on the site.

The weaker spot is product naming and copy. Several blends carry brand-style names, and at least one blend description and page address use wellness-style language. That falls short of strict research-use labeling, so this check is marked partial.

Ordering, Payment and Shipping Within the US

The store ships only within the United States. The shipping page lists a flat $15 rate by UPS or USPS, with most orders leaving within 24 hours and orders placed after 2 p.m. Central handled the next business day. It quotes two to five business days in transit, while the FAQ quotes five to seven business days by UPS Ground, so plan around the longer figure.

The FAQ says freeze-dried material holds up at room temperature for several weeks and that ice packs are often unnecessary; no cold-pack option is described. Payment options listed in the FAQ are Visa, Discover, American Express, Apple Pay, Google Pay and ACH bank draft. The terms mention Visa and Mastercard instead, so the checkout page is the final word.

Refunds, Reships and Support

The return policy is strict. All sales are final, and there are no returns or exchanges for a change of mind. Damaged or defective items must be reported within 24 hours of delivery. If the wrong product was shipped, the store replaces the original order.

Once a parcel is with the carrier, loss, theft and transit damage are the buyer's risk unless optional Route protection was added at checkout, in which case claims go through Route. Orders that have been processed cannot be cancelled or changed.

Support runs by phone, email and a contact form, Monday to Friday, 9 a.m. to 5 p.m. Central. The terms ask buyers to contact the store before opening any card dispute.

Verdict: Strong Paperwork, Tight Terms

Ascension Peptides suits labs that want lot-numbered reports from named outside labs and can accept final-sale terms. The documentation is the strongest part of the listing: several batches per product, two labs, LC-MS identity and, on recent reports, contaminant screens.

Before ordering, check:

• that the lot number on the vial matches a report on the product page
• that the report is recent and covers identity as well as purity
• whether to add Route protection for cover against transit loss
• that someone can inspect the parcel within 24 hours of delivery
