Product Overview
TB500 is a synthetic acetylated heptapeptide corresponding to the active region of the thymosin beta-4 protein. Biochemical investigation of this fragment centres on actin-binding behaviour, cytoskeletal reorganisation, and cell motility assays in controlled in-vitro systems.
Specifications
- Formula: C37H65N11O14
- Molar Mass: 887.98 g/mol
- Purity: ≥98% (HPLC)
- Format: Lyophilized powder / Raw chemical reagent
Compliance Notice: For in-vitro laboratory research and analytical testing only. Not for human or animal consumption, clinical use, or therapeutic administration.
Lyophilized Compound Stability
All peptide reagents are supplied as lyophilized (freeze-dried) raw powders to ensure structural stability during transit and storage.
Storage Protocol
Unopened, dry materials should be stored in a cool, dark environment away from direct light and moisture. For extended storage prior to testing, refrigeration or sub-zero storage is recommended in accordance with specific compound handling specifications.
Working Solutions
Once prepared into working solutions for in-vitro analysis, reagents must be kept refrigerated at 2–8°C and handled using standard aseptic laboratory techniques to prevent microbial contamination and thermal degradation.
Compliance Note: Adhering to standard laboratory storage and handling protocols is critical to maintaining compound integrity, analytical purity, and experimental reproducibility.
To ensure optimal long-term purity and stability, store all lyophilized research products in a cool, dry place prior to reconstitution.
Once opened, most products require refrigeration. Reconstituted vials should be kept between 2–8°C and protected from temperature fluctuations. Avoid exposing compounds to excessive heat, moisture, direct sunlight, or recurring freeze-thaw cycles, as these conditions can compromise product integrity during testing.

Placeholder certificate-of-analysis information.
At Prime Core Dynamics, we are committed to accurate fulfillment, strict quality controls, and the prompt dispatch of every order. Due to the specialized chemical nature of research materials and strict regulatory compliance requirements, our policies are strictly enforced to protect product integrity and prevent cross-contamination.
1. All Sales Are Final
Because research compounds, peptides, and chemical reagents require controlled storage conditions to preserve chemical stability, all sales are final.
Once an order is submitted through our platform, it immediately enters our processing pipeline. Orders cannot be canceled, altered, or modified once placed.
2. Returns & Refunds
To maintain chain-of-custody security and regulatory compliance, Prime Core Dynamics does not accept returns or exchanges under any circumstances. Once a package leaves our facility, we cannot verify its storage conditions or temperature controls; therefore, items cannot be returned to inventory.
Refunds or store credits will not be issued for:
- Change of mind, buyer’s remorse, or mistaken orders.
- Refused or abandoned deliveries.
- Incorrect shipping addresses provided by the customer at checkout.
- Claims arising from improper handling, storage, or non-laboratory application.
3. Shipping Damage & Fulfillment Errors
We take full responsibility for internal packing errors or transit damage that occurs prior to confirmed delivery. If you receive an incorrect item, a missing item, or a product damaged in transit, you must notify Prime Core Dynamics in writing within seven (7) calendar days of the carrier’s confirmed delivery date.
Firm Reporting Window: Requests submitted after the 7-day calendar window will be denied without exception.Mandatory Unboxing Verification Protocol
To prevent fraudulent claims and ensure accurate resolution, all claims for shipping damage or missing items mustinclude the following unedited documentation:
- Unboxing Video: A clear, unbroken video recording starting from the sealed package showing the shipping label, opening the box, and inspecting all enclosed contents.
- Packaging Photos: Clear photos of the outer shipping box (showing any external damage) and the shipping label.
- Contents & Packing Slip: High-resolution photos of all items received alongside the enclosed packing slip.
Claims submitted without complete video and photographic evidence will be automatically denied.
Upon verification of an eligible fulfillment error caused by Prime Core Dynamics, we will, at our sole discretion, dispatch a replacement for the affected item(s). Cash refunds are not guaranteed.
4. Delivered Packages & Carrier Risk
Once a carrier marks a shipment as “Delivered” (via GPS tracking or delivery confirmation), ownership and risk of loss transfer entirely to the buyer.
- Prime Core Dynamics is not responsible for packages that are stolen, misplaced, or damaged post-delivery (including theft from mailrooms, porches, front desks, or delivery lockers).
- Refunds, credits, or replacements will not be issued for carrier-confirmed delivered packages.
5. Chargebacks & Payment Disputes
Any credit card chargeback or payment dispute filed for an order marked as "Delivered" by the carrier, or initiated to circumvent our refund, cancellation, or Research Use Only policies, will be vigorously disputed.
We utilize carrier delivery records, GPS coordinates, IP address logs, and your agreement to these terms at checkout to dispute claims. Customers who initiate fraudulent or policy-violating chargebacks will have their accounts permanently terminated and will be barred from future orders with Prime Core Dynamics.
6. Regulatory Acknowledgment
By placing an order with Prime Core Dynamics, you certify that you have read, understood, and agreed to this Cancellations, Returns & Refunds Policy, and acknowledge that all products purchased are strictly intended for in vitrolaboratory research purposes only.
