B7-33 Dosage & Reconstitution Guide
⚠ Human self-use reports exist but published human dosing does not — the relaxin-pathway data is animal work.
Research and educational use only — not medical advice, and not for human consumption. The figures below are summarized from public sources, product labeling, and community reports, and are not a prescription or a substitute for a qualified clinician.
Dosing schedule
The table below reports the doses used in the underlying research or by the community — it is documentation, not a recommendation to replicate at home.
| Phase | Dose | Notes |
|---|---|---|
| Reported community range | 100 mcg | once daily |
| Upper reports | 500 mcg | once daily — least precedent |
Animal studies dosed by body weight (e.g. mg/kg subcutaneous) in cardiac-fibrosis models; the single-chain design avoids relaxin's cAMP pathway.
Timing & cycling
Anecdotal use is once daily; no validated schedule exists.
Cycle length. Short exploratory blocks in reports (2–4 weeks).
Storage & handling
Keep the lyophilized (unmixed) vial refrigerated at 2–8 °C (36–46 °F) in a dry, dark place — it tolerates short periods at room temperature during shipping. Once reconstituted, store it at 2–8 °C, never frozen, and use it within about 2–4 weeks (sooner if the solution turns cloudy or discolored). Swab the stopper before every draw and use a fresh needle each time.
Key points
- A soluble relaxin-2 mimetic built for the anti-fibrotic arm of the receptor.
- If you are experimenting despite the evidence gap, the 1 mg end with breaks is the defensible end.
What to monitor
No established markers; the animal endpoints (cardiac fibrosis) are not home-measurable.
Legal & prescription status
No legal prescription exists. It is an unapproved research chemical, sold only for laboratory research and labelled 'not for human consumption.' It is not FDA-approved for any human use.
