Ascension Peptides Review 2026: 84 COAs and Purity Checked

Ascension Peptides is a U.S.-based research peptide supplier carrying more than 50 compounds across individual peptides, pre-formulated blends, and metabolic research products. Every batch is independently tested by MZ Biolabs, a third-party analytical laboratory in Tucson, Arizona, using High-Performance Liquid Chromatography with UV and Mass Spectrometry (HPLC-UV-MS). Certificates of Analysis are publicly available, tied to specific lot numbers, and include the analysis date, purity percentage, and analyst signature. For researchers who need verifiable documentation and domestic shipping, Ascension Peptides is one of the more transparent U.S. research peptide vendors operating in 2026.

Independent U.S. third-party testing via HPLC-UV-MS Every batch is tested by MZ Biolabs (Tucson, AZ), an independent analytical laboratory with no operational connection to Ascension. Testing uses High-Performance Liquid Chromatography with UV detection and Mass Spectrometry (HPLC-UV-MS) to confirm both purity percentage and molecular identity. This dual-method approach catches impurities that UV alone may miss.

Public COA library with batch-specific documentation Certificates of Analysis are published on a dedicated page on Ascension's website. Each COA displays the lot number, analysis date, purity result, analyst name, and analyst signature. A recent Semaglutide batch (Lot 04-01260229, analyzed February 24, 2026) returned a verified purity of 99.98% via HPLC-UV-MS — performed by Ken Pendarvis, ChE, Analytical Chemist at MZ Biolabs. Results like this are representative of what Ascension posts publicly, not selectively.

Named blends with individual COAs: Ascension offers several multi-peptide research formulations, each with its own Certificate of Analysis, including:

Wolverine Stack (BPC-157 + TB-500) - recovery and tissue research
KLOW (GHK-Cu, BPC-157, TB-500, KPV)
GLOW (GHK-Cu, BPC-157, TB-500)
FIT Stack (CJC-1295 + Ipamorelin)
Calm + Clarity (nootropic blend including PE22-28 + Pinealon + Selank)

Rare and hard-to-source compounds. Beyond the core catalog, Ascension carries compounds that are difficult to source from most U.S. vendors, including SS-31 (a mitochondria-targeted peptide studied in oxidative stress models), HCG (Human Chorionic Gonadotropin), and PE22-28 (a truncated spinogenin analog studied in neuroplasticity research). This range makes Ascension useful for researchers working outside standard recovery and metabolic protocols.

SS-31 is the research name for elamipretide. In September 2025, the FDA granted elamipretide accelerated approval for Barth syndrome, a rare genetic disorder that disrupts cardiolipin, the mitochondrial lipid SS-31 binds. Our guide to this SS-31 mitochondrial peptide covers that mechanism and the TAZPOWER trial behind the approval.

HCG looks enough like luteinizing hormone to bind LH receptors on the Leydig cells of the testes, where it stimulates testosterone production directly. Gonadorelin and kisspeptin act further up the same chain, and all three are covered in our review of peptides for testosterone production.

Catalog breadth: 50+ active SKUs. The full catalog spans GLP-1 class peptides, recovery-focused compounds, bioregulators, longevity peptides, neuropeptides, cosmetic peptide formulations, and reconstitution supplies, one of the broader offerings among U.S.-domestic vendors.

Wholesale and distributor pricing. Tiered volume pricing is available for wholesalers and distributors, with a formal application process at /wholesale/ on Ascension's site.

Phone-accessible customer support. A direct customer service line is publicly listed, uncommon in this category, and a meaningful signal for researchers who need order or shipping support.

Recovery and Tissue Research Peptides

BPC-157 and TB-500 are the anchor compounds in this category, available individually and as the pre-formulated Wolverine Stack blend. Both carry batch-specific COAs confirming greater than 99% purity via HPLC-UV-MS testing.

GLP-1 and Metabolic Research Compounds

Ascension stocks Semaglutide and Tirzepatide analogs alongside other GLP-1 class peptides for metabolic and weight-related research applications. A verified 2026 COA for Semaglutide (Lot 04-01260229) confirms 99.98% purity measured by HPLC-UV-MS at MZ Biolabs.

Bioregulators and Longevity Peptides

This category includes Epithalon, Thymosin Alpha-1, Pinealon, and NAD+ precursors, compounds studied in cellular aging, immune modulation, and longevity-related research models.

Neuropeptides and Cognitive Research Compounds

Selank, Semax, DSIP, and PE22-28 are available individually and as part of formulated blends. PE22-28 is a spinogenin-derived fragment studied in neuroplasticity and synaptogenesis research, and its inclusion alongside Pinealon and Selank in a single documented blend reflects the depth of Ascension's neuropeptide offering.

Rare and Specialty Compounds

SS-31 (Szeto-Schiller peptide 31) is a mitochondria-targeted antioxidant peptide studied in models of oxidative stress and mitochondrial dysfunction, a compound rarely stocked by U.S. domestic vendors. HCG (Human Chorionic Gonadotropin) is also available for laboratory research use. Researchers working in these areas will find Ascension's catalog more complete than most direct competitors.

All sales are final. Ascension does not accept returns or exchanges and does not issue refunds, for any reason.

If an order arrives damaged, defective or incorrect, you have 24 hours from receiving it to contact Ascension. Past that point, they will not refund or exchange. That is the shortest reporting window of any supplier in the Project Biohacking directory, so open and check the box the day it lands.

Returns are accepted only where Ascension is at fault, and the shipment is not what was ordered. In that case, they replace the original order rather than refunding it.

Damage in transit is the buyer's liability unless Route Shipping Protection was added at checkout. On anything beyond a small order, that add-on is the only route to a remedy for a parcel damaged on the way.

Once an order has been processed or shipped, it cannot be canceled, modified, or returned.

Ascension Peptides is one of several U.S. research peptide suppliers scored in the Project Biohacking directory, alongside Biolongevity Labs and Limitless Biotech. Compared with most competitors, Ascension's primary strengths are its public COA library with named laboratory and analyst attribution, dual-method HPLC-UV-MS testing, named proprietary blends with individual COAs, and access to rare compounds like SS-31 and PE22-28 that most domestic vendors do not carry. The primary constraints, U.S.-only shipping and research-use restriction are standard for this category.

Researchers who need consistent documentation across every batch and access to specialty compounds beyond the typical BPC-157 and GLP-1 catalog will find Ascension worth evaluating closely.

Each listing carries its own certificate, and several carry more than one as batches turn over, so the catalog is worth checking before ordering. Each certificate names the compound and its lot, so a listing can be matched to its batch before an order is placed.

Ascension marks some products down and posts quantity pricing on its product pages. The Ascension Peptides promo code page shows how Project Biohacking's code works alongside those prices at checkout.
