Proper storage is crucial for maintaining peptide integrity:

• Lyophilized Peptides: Store at -20°C (freezer) in original sealed vial
• Reconstituted Peptides: Store at 2-8°C (refrigerator) and use within recommended timeframe
• Long-term Storage: -80°C for extended periods (1+ years)
• Avoid: Repeated freeze-thaw cycles, direct sunlight, moisture exposure

Always use desiccant packs in storage containers to prevent moisture absorption.

Quality suppliers on PeptidesHub provide rigorous testing:

• Third-Party Testing: Independent lab analysis (HPLC, Mass Spectrometry)
• Purity Standards: Minimum 98% purity for most research peptides
• Certificates of Analysis (COA): Available upon request for each batch
• Batch Testing: Every batch tested before release

Always request a Certificate of Analysis when purchasing research peptides to verify purity and authenticity.

Understanding peptide grades is important:

• Research Grade: For laboratory research only, high purity (98%+), not for human consumption, lower cost
• Pharmaceutical Grade: FDA-approved for human use, higher purity (99%+), strict manufacturing standards, higher cost

Important: All peptides on PeptidesHub are research-grade and intended for laboratory research purposes only, not for human consumption.

Follow these steps for proper reconstitution:

1. Use Bacteriostatic Water: Sterile water with 0.9% benzyl alcohol
2. Calculate Volume: Use our Peptide Calculator for proper dilution
3. Add Water Slowly: Let it run down the vial wall, don't spray directly on powder
4. Gentle Swirling: Don't shake vigorously, gentle rotation until dissolved
5. Store Properly: Refrigerate after reconstitution

Never reconstitute with tap water or use expired bacteriostatic water.

The legality of purchasing peptides varies:

• Research Use: Legal to purchase for laboratory research in most countries
• Human Consumption: Not FDA-approved, illegal to sell for human use
• International: Regulations vary significantly by country
• Verify Local Laws: Check your jurisdiction's specific regulations

Important: PeptidesHub only lists peptides intended for research purposes. It is the buyer's responsibility to ensure compliance with local laws.

Yes! Many suppliers on PeptidesHub ship internationally. However:

• Availability varies by supplier and destination country
• International orders may require additional documentation for customs
• Shipping times are longer for international orders (typically 7-21 business days)
• Import duties and taxes are the buyer's responsibility

Important: Check your country's regulations regarding peptide imports before ordering.

Payment methods vary by supplier. Most suppliers on PeptidesHub accept:

• Credit/Debit Cards: Visa, Mastercard, American Express
• Cryptocurrency: Bitcoin, Ethereum, and other major cryptocurrencies
• Wire Transfer: For larger orders
• E-wallets: PayPal, Venmo (where available)

Check the individual supplier's payment options on their product page for specific details.

Verify peptide authenticity through these steps:

1. Request COA: Certificate of Analysis showing purity testing results
2. Check Batch Numbers: Ensure batch number on product matches COA
3. Third-Party Testing: Consider independent testing for critical research
4. Supplier Reputation: Choose suppliers with verified reviews on PeptidesHub
5. Appearance: Lyophilized peptides should be white/off-white powder

Reputable suppliers will always provide documentation upon request.

Understanding the distinction:

• Size: Peptides have 2-50 amino acids, proteins have 50+
• Structure: Peptides are simpler, proteins have complex 3D structures
• Function: Peptides signal, proteins perform diverse cellular functions
• Absorption: Peptides are generally easier to synthesize and study

In research, peptides are often used to study specific protein functions and signaling pathways.

Suppliers take special care when shipping peptides to maintain product integrity:

• Temperature Control: Lyophilized peptides shipped with ice packs or gel packs
• Protective Packaging: Bubble wrap and foam inserts to prevent damage
• Discreet Shipping: Plain packaging without product information on exterior
• Insulated Boxes: For temperature-sensitive products

Most suppliers use expedited shipping to minimize time in transit.

Traveling with research peptides requires careful planning:

• Domestic Travel: Generally allowed with proper documentation (COA, prescription if applicable)
• International Travel: Check destination country regulations, may be prohibited
• Temperature Control: Use insulated travel cases with ice packs
• Documentation: Carry Certificate of Analysis and research documentation

Important: Research peptides are not approved for human use. Traveling with them may be restricted or prohibited in many jurisdictions.
