solyn is a US research-peptide vendor that lists 21 injectable peptides, including TB-500, Thymosin Alpha-1 and BPC-157. Across 11 products with a market median, its prices sit 13% below the median for the same peptide and vial size; it is the cheapest vendor we track on AOD-9604 and TB-500, and pricier on Thymosin Beta-4 and Cartalax. We found certificates for most 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 accepts card and Zelle.

Vanguard Laboratory signs the most of them
oldest Jan 8, 2026
The site names Vanguard Laboratory as its testing lab. These are the vendor’s own flags, not our measurements.
Solyn states its products are tested by third-party labs including Vanguard Laboratory, an ISO/IEC 17025:2017 A2LA-accredited facility (Cert. No. 6377.01.01).

Median price per mg across solyn’s 13-22 priced listings, from Jul 17 ($3.85/mg) to Oct 14 ($3.64/mg) over 86 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.
5 of solyn’s tracked listings changed price in the last 30 days: 5 down, 0 up.
Listed prices at solyn 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.

solyn sits 13% below market the tracked market median on matched peptide/size rows. The catalog in this index is smaller than Peptides Source's. On COA coverage, solyn rates broad and Peptides Source 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 solyn. We found certificates for most of the in-stock products we track. Those certificates were signed by 2 labs, the newest tested August 31, 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 most of the in-stock products we track. The freshest was tested August 31, 2026. Based on the certificates our crawler found; vendors may publish more than we index. Their own testing page is at https://solyn.com. A certificate on file records what a document says; it cannot prove chain of custody or what is in the vial you receive.
solyn states that orders ship from US. This is what the vendor says about itself, not something we have verified.
We have not recorded a shipping cost for solyn. Orders over $200 are listed as shipping free. Their shipping page is at https://solyn.com. Checkout is the only place these figures are binding.
At the time we recorded it, solyn listed credit or debit card and Zelle. Peptide storefronts change processors often, so the options at checkout may differ from what we hold.
We have none on record for solyn. 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 11 graded products, solyn's median price per mg sits 12.7% below the median for the same peptide at the same vial size. We track 22 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 solyn, COA coverage rates broad. The public index contains 40 documents. Reported test dates in this set run from Jan 8, 2026 through Aug 31, 2026. That rating covers the full tracked catalogue for solyn, 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
8 evaluated certificates
5 graded · 3 not graded · 2 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
8 evaluated records

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.
