TB-500 20mg/vial 1 Vial by Bluepeps

Usage

1. Allow the lyophilised TB-500 vial and bacteriostatic water vial to reach room temperature (approximately 20 °C) before handling to reduce thermal shock during reconstitution.
2. Wipe both vial septa with a fresh alcohol swab and allow to air-dry for 30 seconds before needle insertion.
3. Draw 2 mL of bacteriostatic water into a 3 mL syringe, then inject it slowly down the inner glass wall of the TB-500 vial — not directly onto the powder cake — to avoid peptide denaturation.
4. Swirl the vial gently between your palms for 20–30 seconds until the powder is fully dissolved; the resulting solution should be clear and colourless. Never vortex or shake.
5. Using a fresh 29–31 gauge insulin syringe, draw the required volume (e.g. 0.05 mL for 500 mcg from a 10 mg/mL solution), pinch subcutaneous tissue at the injection site, insert the needle at 45°, and inject slowly.
6. Refrigerate the reconstituted vial immediately at 2–8 °C, label it with the reconstitution date, and discard after 28 days regardless of remaining volume.

Frequently asked questions

What should you use to reconstitute TB-500 peptide vials?

Bacteriostatic water (0.9 % benzyl alcohol) is the correct diluent for TB-500 reconstitution. Its benzyl alcohol content inhibits microbial growth, keeping the reconstituted solution stable for up to 28 days at 2–8 °C. Sterile water for injection is a secondary option but offers no preservative protection once the septum is punctured, making it unsuitable for multi-dose vials like this 20 mg format.

How long does reconstituted TB-500 stay stable in the refrigerator?

Reconstituted TB-500 stored at 2–8 °C in bacteriostatic water remains stable for approximately 28 days. Keep the vial toward the rear of the fridge to avoid temperature swings caused by door opening. Never freeze a reconstituted vial — freeze-thaw cycling disrupts the peptide's amino-acid structure, reducing active-content integrity. Discard if the solution becomes cloudy or develops visible particles.

How do you calculate the injection volume for TB-500 with an insulin syringe?

Add 2 mL of bacteriostatic water to the 20 mg vial to create a 10 mg/mL solution. On a U-100 insulin syringe, 1 unit equals 0.01 mL, so a 500 mcg dose corresponds to 5 units (0.05 mL). This ratio makes per-injection maths straightforward and minimises measurement error — a key advantage of the 20 mg high-concentration format compared to lower-dose vials requiring more dilution steps.

Why does Bluepeps TB-500 come in a 20 mg vial rather than the more common 10 mg size?

The 20 mg format is the highest single-vial concentration available in this product group, reducing the number of vials opened during a full loading or maintenance protocol. Fewer vials mean fewer septum punctures, lower contamination risk, and greater reconstitution efficiency. Bluepeps verifies active-content accuracy at exactly 20 mg per vial using reversed-phase HPLC, so the declared concentration is analytically confirmed — not estimated.

Where and at what angle should TB-500 be injected subcutaneously?

Subcutaneous injection into the abdominal fat pad or lateral thigh is standard for TB-500 administration. Use a 29–31 gauge, 8 mm insulin needle inserted at a 45° angle to deposit the solution into the subcutaneous layer without reaching muscle. Rotate injection sites each session to prevent lipohypertrophy and maintain consistent absorption. Pinching the skin before insertion helps isolate the subcutaneous layer in leaner individuals.

Manufacturer

Bluepeps selects its Thymosin Beta-4 API through a sourcing framework that places GMP certification at the supplier level as a non-negotiable entry criterion — raw material origin is documented and traceable before any peptide enters the fill-and-finish workflow. For this TB-500 20 mg vial, two independent analytical gates clear each production lot: reversed-phase HPLC establishes both amino-acid sequence identity and active-content accuracy against the 20 mg declared specification, while a Limulus Amebocyte Lysate endotoxin assay independently quantifies residual pyrogenic load to a defined release threshold. Lyophilisation is performed under ISO-classified cleanroom conditions, and the Batch Tested designation on this listing reflects lot-specific data — not category-level assumptions.
