What Testagen Costs Right Now

WPA currently tracks Testagen at 3 verified vendors. In-stock Testagen vials run from $53.54 to $53.99 — a 1x spread for the same compound. Limitless Biotech holds the lowest sticker price at $53.54. Normalized to milligrams, Testagen costs $2.68/mg on this page. The best per-milligram value is the 20mg vial from Limitless Biotech.

Testagen 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.

Ranked by true cost per milligram, the Testagen listings WPA tracks are: Limitless Biotech — 20mg at $53.54 ($2.68/mg); Swiss Chems — 20mg at $53.96 ($2.70/mg); LA Peptides — 20mg at $53.99 ($2.70/mg), COA purity 99.46%.

Testagen COA Coverage Across Tracked Vendors

1 of the 3 tracked Testagen listings (33%) publish a third-party Certificate of Analysis. Assayed purity on those reports is 99.46%. The most recent Testagen COA on file is dated 2/26. The remaining 2 listings have no published report, so its purity is the vendor's own claim.

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 Testagen batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Testagen

Across 21 Testagen calculator runs logged by the WPA community, the most common dose entered is 100mcg, most often daily (7x/week). The size researchers calculate against most often is the 20mg vial (20 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 200 doses, so the vial size you buy decides how often you reorder as much as the price does.

Testagen Discount Codes

3 of the 3 tracked Testagen listings carry a WPA researcher discount code. The largest live discount is 10% 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 Testagen

Testagen is a synthetic dipeptide (Glu-Trp) from the Khavinson short-peptide bioregulator program, sourced for male reproductive and androgen-aging research. It ships as a lyophilized powder you reconstitute with bacteriostatic water, and is catalogued with the same Glu-Trp sequence as the thymic peptide Thymogen.

Its reported half-life is ~30 min (short-peptide 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 Testagen Comparison

• Price per milligram — Every Testagen listing is normalized to $2.68/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 Testagen listing shows assayed purity and test date so quality is a number, not a claim.
• Stock status — Live in-stock state for each Testagen listing, refreshed on a recurring basis.

Frequently Asked Questions: Testagen

Is it legal and safe to buy Testagen for research?

In the US, Testagen 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 form, sold strictly for laboratory research. The real variable isn't legality, it's quality: unverified suppliers can ship underdosed, impure, or mislabeled material. Every Testagen 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 3 Testagen listings from 3 vendors.

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

A Certificate of Analysis (COA) is the third-party lab report for one specific Testagen batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually Testagen, 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 Testagen specifically, 1 of 3 tracked listings (33%) publish one, with assayed purity of 99.46%, the most recent dated 2/26. Every row in the table links straight to it.

Which Testagen vendor should I pick?

There's no single "best" Testagen 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. 3 vendors currently carry Testagen, and Limitless Biotech holds the best true value at $2.68/mg on the 20mg vial. If you just want the strongest all-round value, the top-ranked Testagen vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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

Judge Testagen 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 sticker price on one vial. The best tracked Testagen listing works out to $2.68/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 Testagen do I need for one full cycle?

Testagen is a Khavinson bioregulator usually run as a short 10–20 day course, and 4 mg once daily is the most common dose in WPA data. At 4 mg per day a single 20 mg vial covers about five days, so a full course needs two to three of the popular 20 mg vials. Across 21 Testagen calculator runs logged here the most common dose is 100mcg daily (7x/week); a 20mg vial covers roughly 200 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 Testagen?

Yes — many verified Testagen 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. 3 of the 3 tracked Testagen listings carry a code right now, the largest worth 10% off. Each listing shows the current code and the discounted price where one exists.
