Cortagen COA Coverage Across Tracked Vendors

1 of the 1 tracked Cortagen listings (100%) are marked as having COA availability in WPA's listing data; this marker is not independent verification. A purity value is recorded for 1 listing; purity alone does not establish identity or independent testing. The recorded purity value is 99.74%. 1 listing records more Cortagen in the vial than the label claims; check the vendor's report and batch before drawing conclusions. The latest COA date recorded in WPA's listing data is 5/26.

To assess a COA, inspect the actual report for the independent lab, test date, and a batch and vial size matching the Cortagen offer. WPA's listing fields do not establish that a report was independently verified.

How Researchers Actually Dose Cortagen

Across 4 Cortagen calculator runs logged by the WPA community, the most common dose entered is 1mg, most often daily (7x/week). The size researchers calculate against most often is the 20mg vial (4 runs). The most common bacteriostatic water volume is 2mL, which is what sets the draw marks on the syringe for that dose. At that dose a 20mg vial yields roughly 20 doses, so the vial size you buy decides how often you reorder as much as the price does.

Cortagen Discount Codes

1 of the 1 tracked Cortagen listing carries a WPA researcher discount code. The largest live discount is 15% off. Every price and per-milligram figure on this page is the post-discount number, so you are never comparing a discounted listing against an undiscounted one. Codes change and some exclude sale items or carry order minimums.

About Cortagen

Cortagen is a synthetic Ala-Glu-Asp-Pro (AEDP) tetrapeptide from the Khavinson program, sourced for brain/cortex-tissue and aging research. It ships as a lyophilized powder you reconstitute before use, so the real vendor difference is what the certificate of analysis (COA) shows.

Its reported half-life is ~few hours (bioregulator estimate), which is the main reason the community cadence above looks the way it does. Not FDA-approved for any indication.

How to Read the Cortagen Comparison

  • Price per milligram — Every Cortagen listing is normalized to $2.93/mg-style unit pricing, so a small cheap vial cannot hide a worse real cost than a larger one.
  • COA metadata and purity — 1 Cortagen listing is marked for COA availability, and 1 has a recorded purity value. These fields do not independently verify a report.
  • Stock status — Live in-stock state for each Cortagen listing, refreshed on a recurring basis.

Frequently Asked Questions: Cortagen

Is it legal and safe to buy Cortagen for research?

In the US, Cortagen is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. It is a Khavinson peptide bioregulator with no approved human use, sold strictly for laboratory research. The real variable isn't legality, it's quality: unverified suppliers can ship underdosed, impure, or mislabeled material. WPA records COA-related listing fields where supplied, but does not independently verify every report. Inspect the actual batch report and its laboratory, identity testing, and date before drawing conclusions. Right now that screen covers 1 Cortagen listing from 1 vendor.

How do I verify a Cortagen COA so I'm not getting an underdosed vial?

A Certificate of Analysis (COA) may report tests for a specific Cortagen batch. Check that the report identifies the compound (actually Cortagen, not a substituted or underdosed bioregulator), names the laboratory, describes the test method and result, and matches the offered batch and date. A recorded purity value or COA-availability flag in WPA's listing data is not independent verification. Open the vendor listing and inspect the actual report before drawing conclusions. For Cortagen specifically, 1 of 1 tracked listings (100%) are marked as having COA availability in WPA's listing data; that marker is not independent verification. A purity value is separately recorded for 1 listing; purity alone does not establish identity or independent testing. The latest COA date recorded in the listing data is 5/26.

Which Cortagen vendor should I pick?

There's no single "best" Cortagen vendor — it depends on what you weigh most. WPA ranks tracked listings using recorded purity and date fields where available, visitor click activity, price, stock status, and discount data; this ranking is not independent verification of a report. Short Khavinson peptides need careful synthesis verification, so favor vendors with a recent, thorough COA. Only Peptira stocks Cortagen among tracked vendors right now, so there is no price competition to arbitrage — weight the COA rather than the price. Review the actual report and confirm its batch details before making a decision.

How much does Cortagen cost — and how do I know I'm not overpaying?

Judge Cortagen by true price per milligram, not the sticker price on one vial — a cheap small vial often costs more per mg than a larger one. It most often ships in 20 mg vials, so compare $/mg across those rather than the per-vial price. The best tracked Cortagen listing works out to $2.93/mg on the only stocked size, a 20mg vial. WPA normalizes tracked listings to $/mg, and the live cost-per-month card estimates your spend at the most common dose. The one catch: the lowest $/mg sometimes means buying a bigger vial than your cycle needs.

How much Cortagen do I need for one full cycle?

Cortagen is usually run as a short 10–20 day course at low microgram doses, so a single 20 mg vial covers multiple courses and lasts a long time. Across 4 Cortagen calculator runs logged here the most common dose is 1mg daily (7x/week); a 20mg vial covers roughly 20 of them, and that is the figure the cost-per-month card on this page is built on. Protocols vary and this reflects the most common community setup, not medical advice — research use only. Use the cost-per-month card and the calculator on this page to size your exact run, then buy enough to finish a cycle without re-ordering mid-protocol.

Are discount codes available for Cortagen?

Yes — many verified Cortagen vendors offer WPA researcher discount codes, and those savings are already baked into the $/mg ranking on this page, so you're never comparing a pre-discount price against a post-discount one. Codes do change, and some exclude sale items or carry order minimums. 1 of the 1 tracked Cortagen listings carry a code right now, the largest worth 15% off. Each listing shows the current code and the discounted price where one exists.
