How Researchers Actually Dose B7-33
Across 1 B7-33 calculator runs logged by the WPA community, the most common dose entered is 10mcg, most often daily (7x/week). The size researchers calculate against most often is the 1mg vial (1 runs). The most common bacteriostatic water volume is 0.5mL, which is what sets the draw marks on the syringe for that dose.
About B7-33
B7-33 is a single-chain peptide analogue of the B-chain of human relaxin-2 (H2 relaxin), engineered by the Bathgate group at the Florey Institute to retain the anti-fibrotic and vasodilatory signalling of the parent hormone while eliminating the disulfide-bridged A-chain that makes full-length relaxin difficult and expensive to manufacture. It is an unapproved research peptide with no human trials reported.
Its reported half-life is ~15 min (estimated), which is the main reason the community cadence above looks the way it does. Academic research peptide.
Frequently Asked Questions: B7-33
Is it legal and safe to buy B7-33 for research?
In the US, B7-33 is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. B7-33 is an experimental single-chain relaxin analog with no approved human use, sold only 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.
How do I verify a B7-33 COA so I'm not getting an underdosed vial?
A Certificate of Analysis (COA) may report tests for a specific B7-33 batch. Check that the report identifies the compound (actually B7-33, not an underdosed or mis-synthesized peptide), 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.
Which B7-33 vendor should I pick?
There's no single "best" B7-33 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. Review the actual report and confirm its batch details before making a decision.
How much does B7-33 cost — and how do I know I'm not overpaying?
Judge B7-33 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. 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 B7-33 do I need for one full cycle?
B7-33 research doses vary by protocol, so there is no fixed cycle size. Use the calculator on this page to size your run from your intended dose and cadence. Across 1 B7-33 calculator runs logged here the most common dose is 10mcg daily (7x/week); 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 B7-33?
Yes — many verified B7-33 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. Each listing shows the current code and the discounted price where one exists.
