What Is the ProPeptide TB-500 20mg Pen?
TB-500 is the N-acetylated seven-amino-acid peptide Ac-LKKTETQ, corresponding to residues 17-23 of full-length thymosin beta-4 (Tβ4). Full-length Tβ4 is a separate 43-amino-acid molecule of approximately 4,963 Da. This product is the 889 Da fragment; TB-500 and full-length Tβ4 should not be described as the same substance, and research on the full-length parent peptide should not automatically be attributed to this fragment.
The ProPeptide 20mg pen is a pre-filled FlexiPen device with a 20mg / 3mL label claim, ready to use out of the box. No reconstitution, no bacteriostatic water, no syringes to draw. The printed click guide is based on that label claim and ranges from a nominal 1mg setting (15 clicks) to a nominal 5mg setting (75 clicks). The box includes 10 pen needles.
Product specifications and batch documentation are kept product-specific and current. The product is not a licensed medicine and is sold as a research peptide.
Why Buy TB-500 20mg from ProPeptide?
Pre-filled FlexiPen format.
A ready-to-use pen with a 20mg / 3mL label claim. No reconstitution, no bacteriostatic water, no syringes to draw. The printed guide provides label-based settings from a nominal 1mg to a nominal 5mg.
Product-specific documentation.
Specifications and documentation are kept product-specific and current.
Available alongside BPC-157.
TB-500 and BPC-157 are frequently compared or co-investigated in research settings. They are distinct peptides with separate evidence bases; no combined outcome is claimed. We stock BPC-157 separately as a 10mg vial and as a fixed 5mg + 5mg BPC-157 / TB-500 blend vial.
Same-day Dubai delivery.
Orders placed before 4 PM ship same day within Dubai. Outside Dubai, order before 12 PM (noon) for next-day delivery. Orders placed on Saturday will be delivered on Monday, and Sunday delivery is not available outside Dubai. Delivery costs AED 50 below AED 1,000 and is free from AED 1,000. Cold-chain insulated packaging maintains the +2 to +8°C range from our facility to your door.
Direct from ProPeptide.

Research Context: TB-500 Fragment vs Full-Length Tβ4
Research literature and vendor copy often use TB-500 and full-length Tβ4 interchangeably. This product is the 889 Da Ac-LKKTETQ fragment, so findings from the 43-amino-acid parent peptide should not be presented as evidence for the fragment without qualification.
Parent-peptide actin biology
Full-length Tβ4 is a G-actin-sequestering peptide, and LKKTET lies within its actin-binding region. Whether the N-acetylated 17-23 fragment reproduces the full-length molecule's behaviour is a separate research question.
Fragment comparison
Research may compare Ac-LKKTETQ with full-length Tβ4 and non-acetylated LKKTETQ. These are distinct substances, and findings should not be combined without qualification.
Analytical characterization
Peptide purity, concentration, molecular identity, and salt form are separate measurements and should be documented independently.

Frequently Asked Questions
Where can I buy the ProPeptide TB-500 20mg pen in Dubai or the UAE?
ProPeptide ships the TB-500 20mg pen directly from Dubai. Same-day delivery is available on orders placed before 4 PM in Dubai. Outside Dubai, Saturday orders are delivered on Monday. Delivery costs AED 50 below AED 1,000 and is free from AED 1,000. The pen ships in cold-chain packaging.
What is the difference between TB-500 and Thymosin Beta-4?
Full-length thymosin beta-4 (Tβ4) is a 43-amino-acid molecule of approximately 4,963 Da. The TB-500 in this product is Ac-LKKTETQ, the N-acetylated seven-amino-acid fragment corresponding to Tβ4 residues 17-23, with a reference mass of 889 Da. They are distinct substances and should not be used interchangeably.
What is the difference between the TB-500 pen and the 10mg vial?
The pen is pre-filled with a 20mg / 3mL label claim, so it requires no reconstitution, bacteriostatic water, or syringe draw. The separate 10mg vial is a lyophilized powder format that you reconstitute with bacteriostatic water in your lab.
How do I dose the TB-500 pen?
The printed click guide is based on the pen's 20mg / 3mL label claim: 15 clicks is the nominal 1mg setting and 75 clicks is the nominal 5mg setting. The printed guide reflects the label claim and is not a measured click-to-volume delivery result. Each box includes 10 pen needles.
Can I stack TB-500 with BPC-157?
TB-500 and BPC-157 are frequently compared or co-investigated in research settings, but a combined outcome should not be assumed. They are distinct peptides with separate evidence bases. ProPeptide stocks BPC-157 separately as a 10mg vial and as a fixed 5mg + 5mg BPC-157 / TB-500 blend vial.
What is the ProPeptide TB-500 20mg pen price?
The ProPeptide TB-500 20mg pen is AED 400 for a single pre-filled pen labelled 20mg / 3mL, with lower per-pen pricing on 2-pen and 5-pen bundles. Same-day Dubai delivery is available before 4 PM. Outside Dubai, Saturday orders are delivered on Monday. Delivery costs AED 50 below AED 1,000 and is free from AED 1,000.
How should I store the TB-500 pen?
Store between +2 and +8°C (standard refrigerator temperature). Do not freeze. Protect from light. The pen ships in cold-chain insulated packaging in its outer carton and should be refrigerated immediately on receipt.
