nuscience is a US research-peptide vendor based in Albuquerque, NM that lists 52 injectable peptides, including Melanotan II, Semax and Thymosin Alpha-1. Across 50 products with a market median, its prices sit level with the median for the same peptide and vial size; it is the cheapest vendor we track on ACE-031 and PEG-MGF, and pricier on Glutathione and Cagrilintide. We found certificates for around some of the in-stock products we track. Based on the certificates our crawler found; vendors may publish more than we index. Shipping is free over $200. It does not accept returns.

Median price per mg across nuscience’s 31-64 priced listings, from Jul 18 ($7/mg) to Oct 15 ($5.47/mg) over 34 observed days. The mix of products behind the median changes as listings come and go, so this tracks the catalog as well as the prices.
1 of nuscience’s tracked listings changed price in the last 30 days: 1 down, 0 up.
Listed prices at nuscience against the median price per mg for the same peptide at the same vial size, across every vendor we track. Vendors change prices without notice, so check the current listing before you order.

nuscience sits At market price the tracked market median on matched peptide/size rows. The catalog in this index is smaller than Cenexa Labs's. On COA coverage, nuscience rates partial and Cenexa Labs rates none found. 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.
Pricing data cannot settle that question, and we do not test products or verify fulfillment. Here is the evidence we do hold for nuscience. We found certificates for around some of the in-stock products we track. Those certificates were signed by 3 labs, the newest tested July 23, 2026. 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 around some of the in-stock products we track. The freshest was tested July 23, 2026. Based on the certificates our crawler found; vendors may publish more than we index. Their own testing page is at https://nusciencepeptides.com/nuscience-lab-test-results/. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
nuscience states that orders ship from US 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 nuscience. Orders over $200 are listed as shipping free. Their shipping page is at https://nusciencepeptides.com/peptide-handling-storage/. Checkout is the only place these figures are binding.
We have none on record for nuscience. 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.
Across 50 graded products, nuscience's median price per mg sits level with the market median. We track 50 products from them in total. Price per mg is the comparison unit: a cheaper vial holding less is not a cheaper product.
Product documentation
Across the tracked peptide products we hold for nuscience, COA coverage rates broad. The public index contains 106 documents. Reported test dates in this set run from Jul 23, 2024 through Jul 23, 2026. That rating covers the full tracked catalogue for nuscience, 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
10 evaluated certificates
10 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

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.
