Frequently Asked Questions

Research peptides are short chains of amino acids linked by peptide bonds. They are synthesized for use in in-vitro laboratory studies, biological research, and analytical testing to understand cellular processes, receptor interactions, and molecular signaling.

No. All products sold by Peptides Vaults are strictly for laboratory research use only. They are not intended for human consumption, diagnostic use, therapeutic use, or veterinary applications under any circumstances.

The FRUO designation indicates that a chemical or biological product has not been approved by regulatory bodies (like the FDA) for clinical or medical use. It legally restricts the use of the product to controlled laboratory environments by qualified researchers.

While a specific license is not required to browse our catalog, by purchasing from us, you agree to our Terms of Service affirming that you are a qualified researcher, institution, or laboratory professional familiar with the safe handling of these materials.

Lyophilized peptides have been freeze-dried into a solid powder or "puck." This process removes moisture, significantly increasing the compound's stability and shelf life. Liquid peptides have already been reconstituted with a solvent and have a much shorter shelf life.

Yes. Our research peptides are manufactured using advanced Solid-Phase Peptide Synthesis (SPPS), ensuring high purity, consistency, and exact amino acid sequencing without biological contamination.

Currently, our catalog consists of pre-synthesized, standardized research peptides. For inquiries regarding bulk custom synthesis, please contact our support team to discuss your laboratory's specific requirements.

Yes, our lyophilized peptides are processed in specialized cleanroom environments and sealed in sterile vials to ensure they are free from biological contaminants prior to dispatch.

We utilize independent, third-party analytical laboratories to test every batch of our peptides. Products are not released for sale unless they meet our stringent purity requirements, typically exceeding 99%.

High-Performance Liquid Chromatography (HPLC) is an analytical chemistry technique used to separate, identify, and quantify each component in a mixture. We use it to verify the exact purity percentage of our peptides.

Mass Spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of ions. It is used alongside HPLC to confirm the exact molecular weight and structural identity of the peptide chain.

The vast majority of our catalog is certified at 99% purity or higher. The specific purity of each batch is documented on its corresponding Certificate of Analysis (CoA).

Yes, we believe in complete transparency. CoAs for our current batches are available on the respective product pages or upon request via our customer support team.

Lyophilized peptides can sometimes appear differently between batches (e.g., a solid puck vs. loose powder). This is due to variances in the freeze-drying process and the addition of mannitol (a stabilizing buffer), not a difference in the actual active peptide quantity.

No. A lyophilized puck is highly fragile and can break into powder during transit. This structural change does not affect the chemical integrity, purity, or effectiveness of the peptide.

Our peptides are synthesized by top-tier global laboratories adhering to strict ISO and cGMP standards, and undergo final quality control and testing domestically before being distributed.

For short-term storage (up to 1-2 months), lyophilized peptides can be kept at room temperature away from direct sunlight. For long-term storage, they should be kept in a freezer at -20°C (-4°F) or colder.

Lyophilized peptides are remarkably stable and can withstand elevated temperatures for several weeks without degrading. Shipping transit times will not harm the structural integrity of unmixed products.

When stored properly at -20°C, lyophilized peptides remain stable for 24 to 36 months.

Bacteriostatic Water (BAC water) is the standard and most highly recommended solvent for reconstituting peptides, as it contains a small amount of benzyl alcohol to prevent bacterial growth and extend the shelf life of the mixed solution.

Once reconstituted with a solvent, peptides must be stored in a refrigerator between 2°C and 8°C (36°F - 46°F). Do not freeze peptides after they have been reconstituted, as this can damage the molecular structure.

When mixed with Bacteriostatic Water and stored properly in a refrigerator, most reconstituted peptides will remain stable and viable for 3 to 4 weeks.

Some specific peptides are naturally less soluble in water and may require a few minutes to fully dissolve, or may require a gentle swirl. If cloudiness persists, adding a small amount of dilute acetic acid (for basic peptides) can aid solubility. Check the specific peptide's solubility profile.

No. Peptides are delicate amino acid chains. You should never shake the vial violently. Instead, allow the solvent to gently run down the side of the vial, and gently swirl or roll the vial between your fingers until dissolved.

Orders can be placed directly through our secure website. Simply browse our catalog, add the desired research compounds to your cart, and proceed to our encrypted checkout page.

We accept major credit/debit cards, bank transfers, and select cryptocurrencies (such as Bitcoin) to provide our clients with secure, flexible, and discreet payment options.

Absolutely. Our website utilizes industry-standard SSL encryption, and we partner with secure, PCI-compliant payment processors. We never store your raw credit card data on our servers.

Yes, we offer worldwide shipping. However, clients are responsible for understanding their local laws and customs regulations regarding the importation of research chemicals before placing an order.

Domestic orders typically arrive within 3-5 business days. International shipping times vary based on location and customs processing, usually ranging from 7 to 14 business days.

All orders are packaged securely and discreetly in plain, unmarked padded envelopes or boxes to ensure privacy and the safe arrival of your delicate research materials.

Due to the sensitive nature of research chemicals, we generally cannot accept returns, as we cannot guarantee the integrity of the product once it leaves our facility. However, if there is an error on our end, please contact support for a resolution.

While rare, international customs seizures can happen. We provide necessary documentation, but the buyer assumes all risk for international imports. We review these situations on a case-by-case basis; please contact our support team if your tracking indicates an issue.
