Frequently asked questions

Both are sterile. Bacteriostatic water contains ~0.9% benzyl alcohol, which inhibits bacterial growth so a reconstituted vial can be used over a period (typically weeks, refrigerated). Sterile water has no preservative and is generally intended for single use, since once opened there's nothing stopping microbial growth. See Learn for reconstitution basics.

1 mg = 1,000 mcg. Confusing the two is a 1,000× error and one of the most dangerous mistakes in this space. "Units" are different again: on a U-100 insulin syringe, 100 units = 1 mL — a unit is a mark of volume on the barrel, not a dose of drug. Our converter exists specifically to keep these straight.

That's pure arithmetic: concentration = (mg in the vial × 1000) ÷ mL of water, giving mcg/mL; then draw volume = your dose ÷ concentration. The reconstitution calculator does this and converts to syringe units. Note: the calculator does the math on numbers you enter — what dose is appropriate is a medical question for a clinician, not something Peptera advises.

It depends entirely on the compound and your jurisdiction, and it changes over time. Some are FDA-approved prescription drugs (legal with a prescription); some are controlled substances; many are unapproved for human use and may be illegal to obtain or possess. Each Codex profile lists a legal/approval status, but that's general information — check your local law and a professional for your situation.

As a general rule, lyophilised (powder) peptides are stored frozen or refrigerated, and once reconstituted are kept refrigerated and protected from light. Bacteriostatic water extends usable life but doesn't make a solution last indefinitely — respect expiry. Specific storage varies by compound; follow the manufacturer's guidance and a pharmacist/clinician.

A CoA is a lab document claiming a product's identity and purity. In principle it's useful — but a CoA can be faked, outdated, or belong to a different batch than the vial you received. Treat it as a claim, not proof. Third-party testing is more credible than a seller's own paperwork, but still can't guarantee your specific unit. See Reference for more.

No. It's a labelling convention often used to sidestep regulation. The label says nothing about whether a substance is safe, tested, or legal for you to use — and in many cases it's precisely how unapproved drugs are marketed.

Some are legitimate; many are vehicles for fraud. The combination of an anonymous operator + crypto-only + pay-before-you-receive removes every consumer protection at once. See Safety for the red flags before you send anyone money.

No — and it never will. Peptera has no store, no affiliate links, no sponsors, and does not source, broker, or recommend any product or seller. It exists to inform. If a site is teaching you and selling to you, treat that conflict of interest as a warning.

No. We provide reconstitution/dose math (arithmetic on numbers you enter) and educational profiles, but not "use this much on this schedule" protocols. That's the line between education and instructing self-administration of drugs that require a licensed provider.

For a medical reaction, contact a clinician or emergency services immediately — don't wait. For fraud, preserve your records and report it (see Resources for links to IC3, the FTC, FDA, and Poison Control). You're a victim of a crime — reporting it is appropriate.
