Not enough matched products to compute a price position for nexaph. The catalog in this index is smaller than Fusion Peptide's. On COA coverage, nexaph rates broad and Fusion Peptide rates partial. Based on the certificates our crawler found; vendors may publish more than we index.
The honest comparison unit is price per mg on matched peptide/size rows. COA coverage is presence of a current indexed document, not purity-as-quality. See the Evidence Atlas and how to read a COA.
Evidence boundary: Listed prices, stock signals, and indexed COA documents are observations. They do not establish legitimacy, authenticity, safety, sterility, chain of custody, product quality, fulfillment, or suitability. No vendor is endorsed.
We have indexed 9 public posts naming nexaph in the last 180 days (9 on Reddit across everything we hold), the most recent on Jun 14, 2026. These are links, not findings: we have not verified anything claimed in them.
Pricing data cannot settle that question, and we do not test products or verify fulfillment. Here is the evidence we do hold for nexaph. We found certificates for most of the in-stock products we track. Those certificates were signed by 1 lab, the newest tested October 20, 2025. Based on the certificates our crawler found; vendors may publish more than we index. We have been recording their prices since July 3, 2026. Read each certificate yourself, check that its lot and compound match what you are buying, and treat anything we have not recorded as unknown rather than as an answer.
We found certificates for most of the in-stock products we track. The freshest was tested October 20, 2025. Based on the certificates our crawler found; vendors may publish more than we index. Their own testing page is at https://coa.nexaph.com. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
nexaph states that orders ship from domestic U.S. facility. They state that they do not ship internationally. This is what the vendor says about itself, not something we have verified.
We have not recorded a shipping cost for nexaph. Orders over $200 are listed as shipping free. Stated delivery is up to 2 days. Their shipping page is at https://nexaph.com/pages/shipping-policy. Checkout is the only place these figures are binding.
At the time we recorded it, nexaph listed credit or debit card. Peptide storefronts change processors often, so the options at checkout may differ from what we hold.
We have none on record for nexaph. When a code we can verify appears, it shows on this page and the prices here are adjusted for it; until then, every figure on this page is the list price.
Product documentation
Across the tracked peptide product we hold for nexaph, COA coverage rates broad. The public index contains 3 documents. Reported test dates in this set run from Oct 20, 2025 through Oct 20, 2025. That rating covers the full tracked catalogue for nexaph, including products that are currently out of stock, so it can differ from the in-stock rating above. Based on the certificates our crawler found; vendors may publish more than we index.

Certificate assessment
1 evaluated certificates
1 graded · 0 not graded · 0 in the A range.
The sample prioritizes up to ten popular peptides from this vendor. Grades assess the document and its reported tests, not the vendor’s whole catalog or the safety of a product.
Automated checks can make mistakes. Open “Why this result?” for the reason and any review notice, and check the linked COA’s lot against your product. How grading works
1 evaluated record
Document grade
X2: The certificate shows no identity test, so there is no evidence the vial contains the peptide on the label. Ask the vendor for a report that confirms identity by mass spectrometry.
Document check: fail.
Lab record: not confirmed.

A record appears on file after our pipeline identifies the document as a certificate of analysis and matches its printed compound to a catalog peptide. The record cannot prove authenticity, chain of custody, sterility, product safety, or suitability for use.
These are counts of documents in our index, and a coverage rating of what our crawler found. They do not grade vendor quality, legitimacy, or safety. Printed fields can contain transcription errors. “Older record” means the reported test date is more than 18 months old.
