Always consult a qualified healthcare professional before use.
Store lyophilized (unreconstituted) peptides at -20°C for long-term storage, or 2–8°C for short-term. After reconstitution, refrigerate at 2–8°C and use within 30 days.
Keep away from direct sunlight. Do not freeze reconstituted solutions.
Peptide vial, BAC water, alcohol swabs, insulin syringe
Wipe tops of both vials with alcohol swabs
Pull 1–2 mL of BAC water into syringe
Release water slowly along vial wall, not directly on powder
Roll between palms until dissolved. Never shake.
Refrigerate 2–8°C, use within 30 days
Published findings on KPV from peer-reviewed journals.
Yes. Bacteriostatic water (BAC water) is required to reconstitute lyophilized (freeze-dried) peptides. It contains 0.9% benzyl alcohol which prevents bacterial growth, keeping your reconstituted peptide safe for multiple uses over up to 30 days.
Unreconstituted: store at -20°C (freezer) for long-term, or 2–8°C (fridge) for short-term. After reconstitution: always refrigerate at 2–8°C and use within 30 days. Keep away from direct sunlight.
Results vary by individual and protocol. In research settings, measurable effects are typically observed within 1–4 weeks depending on the specific peptide, dosage, and application. Consult a qualified professional for guidance.
Verified suppliers typically include a full third-party COA verifying purity (99%+), identity, and sterility. We recommend only sourcing from vendors that provide batch-specific testing data.
We list verified suppliers above that have been independently reviewed for product quality, testing transparency, and shipping reliability. Always verify COA data before sourcing.
Mild injection site redness, temporary swelling, minor bruising at the application area.
Headache, nausea, dizziness, fatigue, or mild water retention in some cases.
Always consult a qualified healthcare professional before use. Discontinue immediately if adverse effects occur.
Always source from verified suppliers. Look for vendors that provide batch-specific COAs, use temperature-controlled shipping, and maintain transparent testing protocols.
Reputable suppliers typically offer free or low-cost shipping with cold-chain packaging to preserve compound integrity during transit.
XPep independently reviews suppliers listed on our platform based on testing standards, shipping practices, and community feedback.
We verify every data point. All compound information on XPep is cross-referenced against published research, verified supplier data, and community feedback.
If you spot an error or have updated information, reach out to our team and we will review and correct it promptly.
Our goal is to be the most accurate peptide reference available, updated continuously.
Know your local regulations. Peptide research compounds may be subject to different regulations depending on your country and intended use.
XPep provides information for educational and research purposes only. Always verify the legal status of any compound in your jurisdiction before sourcing.
Verified suppliers listed on our platform typically handle customs documentation for international research orders.
COAs are the gold standard. A Certificate of Analysis from an independent third-party laboratory verifies purity, identity, sterility, and potency.
Always request batch-specific COAs (not generic ones) when sourcing any research compound. Purity should be 99%+ for research-grade peptides.
Verified suppliers on XPep are required to provide batch-specific testing data for every compound they offer.
