Cortagen Peptide For Sale

What Cortagen Costs Right Now

WPA currently tracks Cortagen at 1 verified vendor. The cheapest in-stock Cortagen listing is $58.65. Peptira holds the lowest sticker price at $58.65. Normalized to milligrams, Cortagen costs $2.93/mg on this page. The best per-milligram value is the 20mg vial from Peptira.

Cortagen is stocked in a single size: 20mg vials. Because vials of different strengths rarely scale linearly in price, the per-milligram column is the only fair way to rank them.

Cortagen COA Coverage Across Tracked Vendors

1 of the 1 tracked Cortagen listings (100%) publish a third-party Certificate of Analysis. Assayed purity on those reports is 99.74%. 1 listing reports more Cortagen in the vial than the label claims, which lowers the real cost per milligram below the printed price. The most recent Cortagen COA on file is dated 5/26.

A COA is only worth what it proves: it has to name the independent lab, be dated within the last 12 months, and match the exact Cortagen batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

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 status and purity — The 1 COA-backed Cortagen listing shows assayed purity and test date so quality is a number, not a claim.
• 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. Every Cortagen vendor in the table on this page is screened for a published third-party Certificate of Analysis (COA), which is your one objective quality check. 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) is the third-party lab report for one specific Cortagen batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually Cortagen, not a substituted or underdosed bioregulator), assay/purity (ideally 98% or higher), a named independent lab (not the vendor's own in-house claim), and a recent test date. WPA flags COA status per listing, but a marketing screenshot isn't enough — open the actual COA on the vendor's site before paying. For Cortagen specifically, 1 of 1 tracked listings (100%) publish one, with assayed purity of 99.74%, the most recent dated 5/26. Every row in the table links straight to it.

Which Cortagen vendor should I pick?

There's no single "best" Cortagen vendor — it depends on what you weigh most. WPA ranks every verified vendor by a composite of assayed purity, COA recency, lifetime click popularity among researchers, final price, and in-stock plus discount availability. 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. If you just want the strongest all-round value, the top-ranked Cortagen vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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 every verified listing to $/mg, and the live cost-per-month card estimates your real spend at the most common dose, so overpaying becomes obvious at a glance. 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.
