How many units of TB-500 should I draw?

It depends on your vial size, BAC water, and dose. For a 2mg vial with 1mL BAC water, a beginner dose of 2000mcg is typically 100 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to TB-500?

The standard amount is 1mL of bacteriostatic water for a 2mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a TB-500 vial last?

At a beginner dose of 2000mcg 2x/week, a 2mg vial lasts about 1 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for TB-500?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

TB-500 Pharmacokinetics

Pharmacokinetics — Active Dose Over Time

t½ = ~5 hours plasma (functional tissue activity persists 7-10 days)

After 1 half-life (9d): 50% remainsAfter 2 half-lives (17d): 25% remainsAfter 3 half-lives (26d): 12.5% remains

At a 5mg dose: 50% = 2.5mg remaining after 9d. Recommended frequency: 2x/week.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

TB-500 Dosing Protocol

Level	Dose / Injection	Frequency
Beginner	2mg	2x/week
Moderate	5mg	2x/week
Aggressive	7,500mcg	2x/week

Note: Loading phase 4-6 weeks at higher dose, then maintenance at half dose weekly. Systemic action; injection site does not need to be near injury.

About TB-500

TB-500 is the active fragment of Thymosin Beta-4, a naturally occurring protein involved in tissue repair and regeneration. It promotes angiogenesis, reduces inflammation, and upregulates actin — a cell-building protein critical for healing. Unlike BPC-157, TB-500 works systemically, meaning it doesn't need to be injected near the injury site. It's commonly loaded at higher doses for 4-6 weeks, then maintained at half dose.
