To maintain the quality and effectiveness of your peptides, please adhere to the following recommendations:

Either keep your reconsitution water cool and let the peptide come to similar temp or if water is at room temp let the peptide come to room temp to reconstitute. Avoid shocking the peptide.

Storing Freeze-Dried (Lyophilized) Peptides:

Our peptides are supplied in a freeze-dried, or lyophilized, state. In this condition, they can stay stable for roughly 30 days at ambient temperature. If you won't be using them within this period, it's best to keep them in a freezer at approximately -20°C. This way, their shelf life extends to about 6-12 months depending on peptide.

It's essential to note that your freezer should not have 'frost free' or 'auto defrost' features. Continuous freeze/thaw cycles might reduce the peptide's quality over time.

Storing Peptides After Mixing:

After turning the peptides into a liquid solution, they should be kept in a refrigerator at temperatures ranging from 2-8°C. If left at room temperature, they might start to break down in just 24 hours. So, it's advisable to refrigerate them immediately after preparation. When stored correctly in the refrigerator, their potency is retained for 2-8 weeks depending on peptide used.

For extended storage in the refrigerator, many users find it helpful to divide the liquid peptide solution into individual syringes, each holding a single dose. These syringes are then frozen, with one being thawed when needed.

Additional Information:

• We ensure that peptides in stock are stored at temperatures below -80°C for 2 year shelf life.
• However, we order using JIT forecasting so your peptides are fresh and typically newly manufactured.
• Once mixed, handle the peptides gently. Avoid shaking them as it might affect their structure.
• Keep peptides in closed containers, separate from any food items.
• Do not mix peptides in the same vial or syringe
• Use a soon as possible once reconstituted

BAC, deionized water or saline depending on the peptides structure. Different peptides require different mediums - always know your peptides and what water is needed for proper reconstitution and storage.

If in stock you will receive same day if located within the region & typically 1-3 days via post order. If not in stock, it may take up to 15-20 working days depending on customs control and difficulty of manufacturing.

We ship orders at 4PM daily. Any order in stock that is placed after 3PM will be shipped the next working day at 4PM.

No exceptions. Verbal abuse, improper addressess, demands and threats will not be tolerated and you will be blacklisted.

After placing your order, you can choose from several payment options: Wise, debit/credit card, copay, Apple Pay, Google Pay, or USDt (Tether). Once you select your preferred method, we’ll provide the corresponding invoice and payment link. This process ensures flexibility while maintaining security and compliance with regulations. Remember that we are only human do - and abuse is stricly prohibited and will result to a loss of sale no marrter that rhard.

Peptide Storage, Testing, and Quality Assurance

At MindTek, we ensure the highest standards in peptide preservation, classification, and quality control. Our research peptides are meticulously categorized based on molecular length, customization, and stability, optimizing their storage conditions for maximum integrity.

• Cryogenic Storage & Pharmaceutical-Grade Standards

All peptides are stored in -90°C or -40°C cryogenic freezers within a USP797-compliant, sterile facility, adhering to strict pharmaceutical guidelines. This controlled environment prevents degradation, maintains purity, and minimizes contamination risks.

• Fresh Batch Production & Regular Third-Party Testing

We produce fresh peptide batches every 1-2 months and conduct third-party lab testing 4-6 times per year through trusted partners to verify quality and potency.

• Strict Expiry Protocols

Peptides are never stored beyond 8 months, except for highly customized formulations requiring extended preservation. Despite a 4-year labeled shelf life, if a peptide nears our internal 8-month limit, we reconstitute and test it before shipping to ensure absolute consistency and reliability.

• HPLC Reports & Advanced Testing

In-house HPLC (High-Performance Liquid Chromatography) reports are available upon request, though they are not mandatory for standard orders.

• Liquid Nitrogen Transfer for Long-Term Preservation

Peptides that require extended preservation beyond standard storage timelines may be transferred to liquid nitrogen (-196°C) environments for future use.

Our commitment to rigorous quality control guarantees consistency, stability, and purity, making MindTek a leader in research-grade peptide manufacturing and storage.
