Read the methodology.

Ascension Peptides is cheaper on 17 of 21 shared compounds

PeptidePrices can compare 21 compounds at both vendors. The method uses each vendor's cheapest in-stock package per compound, normalized as price divided by vial mg and scaled to the compound's standard research amount (std.). The after-code columns apply each reader code on the same per-standard basis. The table is a trimmed set of the shared compounds. Both sit in a higher price tier, so the code is the main price lever.

Before codes, BioLongevity Labs is lower on 4 compounds and Ascension Peptides on 17. After codes, BioLongevity Labs is lower on 1 and Ascension Peptides on 20. One standard amount of every comparable compound would cost $2131.19 at BioLongevity Labs and $1465.50 at Ascension Peptides before codes, or $1918.07 at BioLongevity Labs and $732.75 at Ascension Peptides after them.

Certificates: 26 exact matches at Ascension, 359 archived records at BioLongevity

An exact match requires a certificate tied to the vendor, compound and strength of a live listing, confirmed against the issuing laboratory's record. Both libraries are vendor-published, so an entry is not proof that a received vial matches the tested lot. The COA library holds the full record.

Ascension Peptides: 85 records, 26 exact listing matches

At its August 14, 2026 review, Ascension's public COA library displayed 85 searchable records by product and batch or lot. The sampled KLOW 80mg product page linked a Kovera Labs report dated July 3, 2026 and an MZ Biolabs report dated February 13, 2026. That is public, named-lab, batch-level documentation.

The listing-evidence lookup counts 26 of 32 in-stock listings with an exact issuer-verified certificate. Kovera Labs accounts for all 26 matched listings, and the newest matched analysis is dated July 14, 2026. The 85-record total is a dated observation. The 26 of 32 count comes from the listing lookup, not from a match of all 85 library records.

The library is vendor-hosted. It does not independently prove a received vial or establish identical coverage for every item. Match the exact product, strength and lot.

BioLongevity Labs: 359 records, 0 exact listing matches

BioLongevity's public searchable COA database contained 359 batch records at the corrected August 2, 2026 review. Its headings included at least one record for each of the 30 current product groups PeptidePrices can compare. PeptidePrices inspected BPC-157 record 261469. The site-hosted image names MDx BioAnalytical Laboratory and BioLongevity Labs as client, with a batch number, HPLC purity, mass-spectrometry identity, a vial image and an endotoxin PASS field.

MDx is a real public laboratory, but its current portal did not return the image's displayed search code 261565. MDx also says its ISO certificate is pending re-accreditation after its March 2026 audit. The listing-evidence lookup found 0 of 38 in-stock listings with an exact issuer-verified certificate.

Finnrick's independent page lists 33 BioLongevity tests, with 25 of 33 classifiable tests passing (76%). BPC-157 is the weaker product signal at 47% across 11 tests. U.S. cGMP manufacturing is unproven: the site does not name the manufacturing plant or publish a certifier, certificate number, certification scope or expiration date. The homepage says 150-plus products while the About page says 80-plus.

Codes: PEPTIDEPRICES50 takes 50% off; PEPTIDEPRICES takes 10% off

• Ascension Peptides: PEPTIDEPRICES50 for 50% off. Terms: Ascension Peptides coupon page.

Where the 50% code flips the winner

The after-code columns show the swing. All figures are per 10mg, BioLongevity first. Epithalon is $47.49 at BioLongevity and $50.00 at Ascension before the code; after it, $42.74 and $25.00. Ipamorelin goes from $79.97 and $100.00 to $71.97 and $50.00. Pinealon goes from $34.99 and $50.00 to $31.49 and $25.00. Oxytocin stays with BioLongevity: $64.97 and $220.00 before, $58.47 and $110.00 after.

Shipping and payment: Ascension publishes US-only terms; BioLongevity's are unverified

Ascension Peptides ships within the United States only. The site states a $15 domestic rate, most orders ship within 24 hours, and delivery typically takes 2 to 5 business days after payment clears. UPS or USPS is used. Checkout lists Visa and ACH bank draft. All sales are generally final, and damaged or incorrect orders must be reported within 24 hours.

BioLongevity Labs publishes fulfillment terms, but PeptidePrices marks its destinations and payment methods as not verified. The site lists an Akron, Ohio business address, a help email and a phone number, and it says it accepts major credit cards. Its terms say paid orders placed before noon Pacific usually ship the same business day, and shipping is free over $400. Its returns page also carries conflicting terms: an initial no-return rule and a later 10-day window for unopened items with a 15% fee. Get written return authorization before sending anything back.

BioLongevity Labs for breadth, Ascension Peptides for shared-compound price

The practical split follows the order, not the brand.

Choose BioLongevity Labs for catalog breadth and card checkout

• You need a compound Ascension does not stock. The stock rows list 17 compounds only at BioLongevity, including Cagrilintide, Bronchogen, Chonluten, Livagen, Ovagen, PNC-27, Pancragen, Prostamax, Thymogen, Thymulin, Vesugen and Vilon.
• You want the larger catalog: 38 in-stock listings across 38 compounds, against 32 listings across 30 compounds at Ascension.
• You want a 359-record public archive to search by product and batch, and you will match the exact lot to the report before ordering. None of the 38 current listings has an exact issuer-verified match.
• You want to pay by major credit card and will confirm the destination and return terms in writing first.

Choose Ascension Peptides for shared-compound price and named-lab batch files

• You are buying a compound both vendors stock and want the lower after-code price. Ascension is lower on 20 of 21 after codes.
• You want a 50% reader code rather than 10%.
• You want batch-level reports from named labs: Kovera Labs on 26 matched listings, plus MZ Biolabs on the sampled KLOW 80mg page.
• You are shipping in the United States, paying by Visa or ACH, and can accept an all-sales-final policy with a 24-hour damage or incorrect-order window.
• You accept that the 85-record library is a dated observation and will check the current listing before ordering.
• Ascension's stock rows list 9 compounds with no BioLongevity listing, including AOD-9604, CJC-1295 No DAC, Glutathione, Selank, Semax and Sermorelin.

Check the price row for the compound you need, then check the certificate for the exact product, strength and lot. The underlying evidence is in the BioLongevity Labs review and the Ascension Peptides review.

PeptidePrices has affiliate relationships with some vendors. Affiliate status carries no weight in scores.
