B-12
10 mL vial
Research Use Only
For research use only. Not for human consumption. Not intended to diagnose, treat, cure, or prevent any disease. Must be 21 or older to purchase.
Measurement Key
mg = milligram; mcg = microgram; 1 mg = 1,000 mcg. mL = liquid volume. A U-100 syringe has 100 marked volume units per mL: one marking is 0.01 mL and ten are 0.10 mL. These markings are NOT peptide International Units (IU). A physical syringe may not have one-unit or half-unit graduations; do not imply it can measure a value more precisely than its scale permits. Concentration = total amount / measured FINAL volume. Quantity in a sample = concentration × sample volume. Required volume = a protocol-specified quantity / verified concentration. The calculator checks arithmetic only; it cannot select a clinical dose or establish suitability, stability or sterility.
Research Information
Contents
10 mL container. B-12 chemical form and concentration are not confirmed. The photo's 10 mg wording does not establish whether it means total content or mg/mL.
Clinical evidence and research limitations
Approved vitamin B-12 products treat documented deficiency and certain deficiency-related anemias. That does not establish an energy or weight-loss benefit in people without deficiency, or identify the contents of this research bottle.
Dosing evidence
Insufficient data to verify. B-12 form, concentration, indication and product-specific instructions are needed before calculating a dose or volume.
Reconstitution
Shown as a prepared red liquid: do not instruct visitors to add water. Identity, concentration and preservative system still require verification.
Measurement example
No verified syringe chart. IF the supplier confirms 10 mg TOTAL in 10 mL, the arithmetic would be 1 mg/mL (1,000 mcg/mL), and one U-100 marking would represent 10 mcg. This is an unverified conditional example, not a product specification.
Possible side effects
Cyanocobalamin labeling reports itching/rash, diarrhea and rare severe allergic reactions; intensive treatment of severe megaloblastic anemia can cause dangerous low potassium. These are formulation/context-specific risks.
Storage
Exact supplier instructions are needed. The reviewed cyanocobalamin label specifies 20–25°C and protection from light, but those directions cannot authenticate or define this bottle.

Source access date: October 25, 2026. Secondary calculation references (peptidedosages.com) are community resources, not clinical trials. Their example volumes do not validate these products.
Responding to possible adverse effects: The side-effect summaries are incomplete and do not establish the safety of the inventory. Unknown risks must not be described as "no side effects." For anyone experiencing breathing difficulty, facial/throat swelling, fainting, severe persistent abdominal pain or other severe symptoms after an exposure, seek urgent medical care and provide the product/lot details.
Preparation and Handling Information
The original product instructions must establish substance identity, component ratio, excipients, compatible diluent, required amount, final volume, mixing method, container suitability, storage and discard interval. A 3 mL container does not automatically require 3 mL water. Any powder displacement and final-volume instructions must be accounted for. Do not transfer the storage rules for a branded finished medicine to a different research powder. No universal refrigerated shelf life, freezer shelf life or "28 days after mixing" period is established for this catalog. Lack of visible particles is not proof of sterility. Do not use a damaged, leaking, unexpectedly altered or undocumented preparation.
