RDAmd

RDAmd peptides are guaranteed 99%+ pure. Every batch is independently tested by accredited U.S. laboratories using analytical methods such as:

• HPLC (High-Performance Liquid Chromatography) for purity profiling
• Mass Spectrometry for identity and molecular weight verification

We provide a Certificate of Analysis (CoA) with every order showing purity results, identity confirmation, and batch-specific details.

A Certificate of Analysis is a third-party lab document that verifies the quality of a specific batch.

• Purity: Should indicate 99%+ (often by HPLC area %)
• Identity: Confirms the correct compound (commonly via mass spectrometry)
• Appearance: Physical description (e.g., lyophilized white/off-white solid)
• Endotoxin (if listed): Common research benchmark is typically < 1 EU/mg

CoAs are batch-specific and are included with your order (or provided upon request).

For laboratory / in vitro research use, reconstitution is typically performed using sterile technique and an appropriate sterile solvent compatible with your protocol.

• Allow the vial to reach room temperature before opening (helps reduce condensation)
• Use aseptic technique (clean surface, sterile tools, minimize exposure time)
• Add solvent slowly down the inside wall of the vial (avoid blasting directly onto the powder)
• Gently swirl or roll until fully dissolved (do not shake vigorously)
• Label with batch/compound, concentration, solvent, and date/time

Bacteriostatic water is sterile water containing a preservative (commonly 0.9% benzyl alcohol) intended to inhibit bacterial growth after puncture in certain controlled applications.

In a lab context, your solvent choice should be based on your protocol requirements (compatibility, stability, sterility, and study design). Always follow your institution’s SOPs and safety guidance.

In research settings, concentration is calculated from the amount of material and the final solution volume:

• Concentration (mg/mL) = Total mass (mg) ÷ Total volume (mL)
• Concentration (µg/mL) = Total mass (µg) ÷ Total volume (mL)

Many labs use internal calculators or LIMS templates to reduce error. Ensure your labels include units and any dilution steps.

Lyophilized (freeze-dried) peptides are generally stable when kept dry and protected from heat and light.

• Short-term (under 3 months): Cool, dark, dry place is commonly acceptable
• Long-term: Refrigeration (2–8°C) or freezing (-20°C) is commonly used
• Avoid repeated temperature cycling and moisture exposure

Post-reconstitution stability depends on the compound, solvent, concentration, and storage conditions.

• Store according to your lab protocol (often refrigerated at 2–8°C for short-term use)
• For longer-term storage, labs often aliquot to reduce contamination risk and repeated handling
• Inspect for unexpected changes (cloudiness, particulates, discoloration) and follow SOPs

We offer same-day fulfillment for weekday orders placed before 2pm (excluding federal bank holidays).

• Standard shipping: Typically 2–3 business days after shipment
• Cold shipping: Lyophilized peptides are generally stable at room temperature during transit and typically do not require cold packs

All orders ship in discreet, unlabeled packaging.

Currently, we ship to all 50 U.S. states.

International availability varies due to customs regulations on research materials. If you need international shipping, contact support with your destination country and we’ll confirm what’s possible. International orders may be subject to local customs fees and import duties.
