We currently are US based and only ship to US at this time.
At Peak Peptide, we only offer peptides that meet or exceed 99% purity, often surpassing 99%, as confirmed by independent third-party testing. This strict verification process ensures our research peptides are of the highest quality, giving you complete confidence in every order.
At Peak Peptides, we dispatch all orders from our U.S. facility, with most customers receiving their shipments within 2-5 business days. Each package comes securely packed and includes tracking updates, no signature required.
Simply add Bacteriostatic Water (BAC Water) to the lyophilized peptide vial in your desired volume. For accurate dosing, we recommend using a peptide calculator app (e.g., Peptide Calculator). This helps ensure optimal concentration for your research needs.Here is a quick video to watch for the basics:
BAC Water is commonly available for purchase from reputable medical supply websites or local pharmacies (including smaller independent ones). For the best results, look for suppliers that specialize in sterile solutions for injections or research. If you're having difficulty locating it, feel free to email us at info@peakpeptide.org, and we'll guide you to reliable sources. Note: Always ensure you're buying from licensed vendors and consult a healthcare professional for proper use and storage.
Our peptides are shipped in lyophilized form, which is stable at room temperature during transit. Once received, store unopened vials in a cool, dry place. After reconstitution, store between 2-8°C (36-46°F), keep refrigerated, avoid repeated freeze-thaw cycles, and protect from direct light.
Our peptides are shipped in lyophilized (freeze-dried) form, which ensures stability during transit. This powder form is highly stable at room temperature and resistant to temperature fluctuations that occur during shipping. Research has shown no significant degradation or loss of purity when lyophilized peptides are exposed to room temperature during typical shipping timeframes. Each batch is verified for purity upon production, and our stability testing confirms maintenance of product integrity during standard shipping conditions. For optimal long-term storage after receiving your order, we recommend storing the lyophilized peptides in a cool, dry place until reconstitution is needed.

All sales are final. Since we’re dealing with sensitive research compounds that require strict quality control, we can’t accept returns or exchanges. Questions about your order? We’re happy to help – just reach out.
Peptides are short chains of amino acids (typically 2-50), serving as building blocks for proteins. In research, they are studied for roles in signaling, enzyme activity, and cellular functions. Peptides differ from proteins in size and complexity but share similar research applications.
Peptides are synthesized using solid-phase peptide synthesis (SPPS), a method where amino acids are sequentially added to a solid support. This process allows for custom sequences and modifications. Our peptides are manufactured under WHO/GMP and ISO 9001:2015 standards to ensure high purity.
Peptides are shorter chains of amino acids (usually less than 50), while proteins are longer and more complex. Peptides are often used in research for specific functions, such as hormone regulation or signaling, while proteins have broader structural roles.
Peptide purity is determined using techniques like HPLC (High-Performance Liquid Chromatography) and mass spectrometry. Our products undergo third-party testing to ensure purity levels of 98% or higher, with certificates available upon request.
Net peptide content refers to the actual amount of peptide in the vial after accounting for salts, counterions, and water. Our products are lyophilized to provide accurate net content, typically specified in the product description.
Our peptides are for research purposes only and are not intended for therapeutic use, diagnosis, or treatment of any condition. Consult a healthcare professional for medical advice, and never use for human or animal consumption.
Lyophilized peptides can be stable for years when stored properly (cool, dry, dark place). After reconstitution, stability varies (typically 2-4 weeks refrigerated). Always check specific product guidelines.
Reconstitution involves dissolving the lyophilized peptide in a solvent like bacteriostatic water to create a solution for research use. Use sterile techniques and calculate concentrations carefully with tools like peptide calculators.
Yes, research-grade peptides are legal to purchase for laboratory use in most jurisdictions, provided they are not marketed or used as drugs. Ensure compliance with local laws and regulations, as some peptides may be controlled substances.
Custom peptides can typically be synthesized up to 50-100 amino acids, depending on the sequence complexity. For longer sequences, contact us at info@peakpeptide.org for feasibility and pricing.
For preliminary studies, 85-95% purity may suffice, while advanced research or sensitive assays require 98%+ purity. Our peptides are tested to meet or exceed 98% purity for optimal results.
Yes, peptides can be modified with labels, conjugates, or cyclization for specific research needs. Contact us for custom modification options.
Peptides are used in studies on hormone regulation, immune response, metabolic pathways, and drug development. They serve as tools for understanding protein interactions and cellular signaling.
Since our peptides are for in-vitro research only, side effects are not applicable to human use. However, researchers should handle them with appropriate safety protocols to avoid contamination or exposure.
Use a peptide calculator app to determine concentrations based on vial size, solvent volume, and desired dose. Always double-check calculations for accuracy in experimental settings.
