Frequently Asked Questions

Research peptides are short-chain amino acid sequences synthesized for use in in-vitro laboratory research and scientific study. They are used by researchers to study biological mechanisms, receptor interactions, and cellular processes. Our products are not intended for human or animal consumption.

Every batch is independently tested by a recognized third-party laboratory. Testing includes HPLC (High Performance Liquid Chromatography) for purity verification (≥98-99%) and Mass Spectrometry for compound identity confirmation. A batch-specific Certificate of Analysis (COA) ships with every order.

All peptides are sold in lyophilized (freeze-dried) powder form in sealed, sterile glass vials. Lyophilized peptides are stable at room temperature during shipping and offer maximum shelf life when stored properly after delivery.

Before reconstitution: Store sealed vials in a cool, dry place. For long-term storage (3+ months), refrigerate at 2-8°C or freeze at -20°C. Avoid direct sunlight and excessive heat.

After reconstitution: Refrigerate immediately at 2-8°C. Use within 30 days for optimal stability. Do not freeze reconstituted peptides. Avoid repeated freeze-thaw cycles.

Yes. We sell bacteriostatic water (BAC water) in 10mL vials, which is the standard solvent used for reconstituting lyophilized peptides for research applications. BAC water contains 0.9% benzyl alcohol as a preservative.

Standard reconstitution procedure:

• Clean the vial stopper with an alcohol swab
• Draw the desired volume of bacteriostatic water with a sterile syringe
• Inject slowly against the glass wall — do not spray directly onto the powder
• Allow to dissolve naturally — gentle swirling is fine, do not shake
• Store reconstituted peptide at 2-8°C

Concentration depends on the volume of bacteriostatic water added:

Formula: Concentration (mg/mL) = Peptide Amount (mg) ÷ BAC Water Volume (mL)

US Domestic: USPS Priority Mail — 2-3 business days. We currently ship to US addresses only.

Orders placed before 2:00 PM CT on business days ship the same day. Full tracking with every order.

Yes. All orders ship in plain, unmarked packaging with no branding, logos, or product descriptions on the exterior. The return address does not identify the contents.

Lyophilized peptides are stable at ambient temperature for standard shipping (2-5 days). During summer months, we include insulated packaging and gel ice packs. We recommend Mon–Wed delivery during hot weather.

Research peptides sold for in-vitro laboratory use are legal to purchase in the United States. They are classified as research chemicals, not pharmaceuticals. It is the buyer's responsibility to verify legality in their jurisdiction.

No. All products are intended strictly for in-vitro research, laboratory use, and scientific study only. They are NOT intended for human or animal consumption, self-administration, or any clinical use. These products have not been evaluated by the FDA.

All sales are final. Exceptions for damaged, incorrect, or missing items (reported within 48 hours with photos), and for verified purity disputes (within 30 days with third-party lab results). See our full Refund Policy.

Yes. MedTides offers premium, third-party tested research peptides for in-vitro laboratory and research use only. All compounds are HPLC-verified at ≥99% purity and come with a Certificate of Analysis. Visit our Shop to browse available compounds.
