The claims this storefront makes
Nexaph is a budget kit seller, and the word kit matters: most of its roughly 60 listings are sold as ten vials at a time, so the BPC 157 listing at $152 is for ten 10 mg vials rather than one. The catalog includes VIP, Thymosin Alpha 1 and Tesamorelin at 10 mg, a KLOW Blend at 80 mg, ampules, GLP-class products, and three coded products the company calls NXP-1P, NXP-2P and NXP-3P, which we quote exactly as listed. The storefront heading reads “Purity 99%+,” and the fine print beneath it guarantees 99 percent only for the three NXP products and 97 percent for everything else. The site names Janoshik Laboratory as its tester and runs a public certificate portal. It describes a “domestic U.S. facility.” It promises money back if a product tests below its stated purity, and same-day shipping before 2 pm Eastern on one page and noon Pacific on another, with delivery in five to seven business days. The one thing a buyer should know is that this company is more open about its testing than its price tier would predict and less open about itself than any buyer should accept.
We read the homepage, the about page and the shipping policy against each other, opened the certificate portal and looked for lot numbers and dates, read the refunds page, fetched the Trustpilot profile, pulled Finnrick’s vendor page, which holds the largest test history of any supplier in our file, and searched FDA correspondence.
What held up when we checked
The laboratory is named and the portal is real. Janoshik Laboratory is identified on the site, and the certificate portal at coa.nexaph.com opens to anyone without an account. A named laboratory plus a portal anyone can open is the baseline for credibility in this market, and Nexaph meets it, which many suppliers charging twice as much do not.
The public reputation is live rather than managed. The Trustpilot profile shows 3.9 from 73 reviews, is unclaimed, and carries a review as recent as September 17, 2026. A profile the company has not tried to curate is at least an honest one, and it is a contrast with the many removed profiles elsewhere in this file.
The guarantee is written down. A qualifying product that tests below its stated purity can be replaced or refunded, and a product more than 10 percent under its stated net fill earns store credit, with full terms at /refunds-and-returns/. Card payment is accepted, shipping is by USPS Priority or UPS, free from $200, and a research-use disclaimer is present. BPC 157 is $152 for a ten-vial kit of 10 mg vials and a BPC-157 and TB4 blend kit at 5 mg each is $188, which on a per-vial basis is deep in the budget tier.
What did not, and what we could not verify
The company cannot say where it is. The about and shipping pages name Shanghai Nexa Pharma Co as the seller. The homepage claims a domestic US facility. Both statements sit on the same website, and nothing reconciles them. There is no street address and no phone number; contact is one email address and a Telegram handle. We record the headquarters as unknown because the supplier has given two incompatible answers, and a buyer should assume the Shanghai entity is the one they are contracting with until the company says otherwise.
The certificates cannot be matched to a kit. Each product on the portal shows one “Active” certificate with older versions behind it, but no lot number or date is visible, and the portal does not describe which methods were run. Whether HPLC, mass spectrometry, endotoxin or sterility testing is performed is unknown from the portal alone. A certificate that cannot be matched to a lot is a general assurance about a product line, not a record of the batch in the box, and that distinction matters more for a company whose independent results vary as widely as this one’s.
The purity heading overstates the guarantee. “99%+” sits over a catalog where only three coded products are guaranteed at 99 percent and everything else at 97. The free-shipping and shipping-cutoff statements also differ between pages. Products are sold mainly as ten-vial kits, and custom batches require a minimum of 30 kits, so there is no way to buy a single 5 mg vial and no single-vial price to compare.
The independent record is the most useful thing in this report, and it is attributed to Finnrick throughout. Finnrick, an independent testing aggregator, holds 295 samples for this vendor, the largest history in our file, and reports that 177 of 294 classifiable tests passed, with the latest test on October 9, 2026. The results vary sharply by product. On the high side, GHK-Cu passed 90 percent of the time and one GLP-class product 76 percent. On the low side, CJC-1295 passed 30 percent, MOTS-c 29 percent, NAD+ 26 percent and another GLP-class product 33 percent. That is not one supplier with one quality standard; it is several product lines with very different track records sold under one name. No FDA warning letter naming Nexaph appears in our record.
Our read
Nexaph is more transparent about testing than its price tier would predict and less transparent about itself than any buyer should accept. A supplier that cannot say which country it is in has a credibility problem that no certificate portal fixes, and a portal without lot numbers cannot tell a buyer whether the kit on their bench is one of the lots that passed.
The Finnrick history is the real specification sheet here. Nearly 300 independent samples show some products passing reliably and others failing most of the time. A research purchaser who orders from Nexaph should read the product-level Finnrick figures before choosing a kit, buy only from the lines that pass, and treat the 97 percent guarantee as the one that applies to them.
