常见问题
TB-500 (Thymosin β-4 Fragment) — 常见问题
What is TB-500?
TB-500 is a synthetic fragment of the naturally occurring protein Thymosin Beta-4 (Tβ4). It is a small, water-soluble peptide widely studied for its role in actin binding, cellular migration, and tissue regeneration. Each IGF1 Shop vial contains 5mg of pure TB-500 in lyophilized form (CAS 885340-08-9). The peptide is sealed under inert gas to preserve activity until reconstitution.
How pure is your TB-500?
Every batch of TB-500 is independently verified at ≥99% purity by reversed-phase HPLC, with molecular identity confirmed by ESI mass spectrometry. We also run LAL endotoxin testing with a release limit of <0.5 EU/mg and full sterility checks. The corresponding Certificate of Analysis (COA) for your exact lot is downloadable from the product page. All testing is performed at ISO 17025-accredited laboratories.
What is the typical TB-500 dose at 5mg?
Most reference protocols describe a two-phase approach: a loading phase of 4-8mg per week split across two injections for the first 4-6 weeks, followed by a maintenance dose of 2-4mg every 1-2 weeks. A single TB-500 5mg vial reconstituted with 2.5mL bacteriostatic water yields 2mg per 0.1mL. Always work from your reconstitution math, not assumptions. Cycle length depends entirely on personal goals.
How do I reconstitute TB-500 5mg?
Add 2-3mL of bacteriostatic water slowly down the side of the vial — do not aim the stream at the powder cake. Swirl gently until fully dissolved; do not shake. Once reconstituted, store TB-500 at 2-8°C and use within 30 days for best stability. Keep the unmixed vial at -20°C in a dry, dark place where it remains stable for up to 24 months.
How does TB-500 compare to BPC-157?
They target different stages of the repair cascade. BPC-157 is a 15-amino-acid gastric peptide that supports vascular signaling and early-phase tissue knitting. TB-500 drives actin polymerization, cellular migration, and angiogenesis at the structural-remodeling stage. Many users run them together — see our BPC-157 + TB-500 blend.
How long does TB-500 take to work?
Reported timelines in user logs vary widely. Acute soft-tissue programs typically run 4-6 weeks of loading before tapering. Chronic or stubborn complaints are often run for 8-12 weeks. Individual response depends on age, baseline tissue status, and the rest of your recovery stack.
Do you ship TB-500 internationally and discreetly?
Yes. We ship TB-500 worldwide in plain, unbranded packaging with no peptide-related markings on the outer label. Domestic and international tracking are provided. Orders above $59 ship free. We accept Bitcoin, USDT, Monero, and major cards, and the merchant descriptor on card statements is generic.
Is the COA tied to my exact vial?
Yes — every TB-500 vial carries a batch number that maps to a specific HPLC, mass-spec, and endotoxin report dated within the synthesis cycle of that lot. You can pull the PDF directly from the product page. We never reuse a previous lot's COA for a new synthesis run.
