TB-500: Dosage, Cycle Length, and How to Track It
What TB-500 is, the loading and maintenance dosing patterns people commonly discuss, how to reconstitute it, and how to track your protocol so you know whether it worked.
TB-500 — a synthetic fragment related to thymosin beta-4 — is widely discussed in the context of recovery and tissue repair, often alongside BPC-157. This guide is an educational overview: what it is, the dosing patterns people commonly describe, how to reconstitute it, and how to track a protocol so the time and money actually buy you an answer.
Important disclaimer
TB-500 is a research peptide. It is not an approved medication for general human use, and the information here is educational, not medical advice. Doses and cycles mentioned are anecdotal community figures, not recommendations. Consult a qualified healthcare provider before using any peptide, and follow the laws in your jurisdiction.
What is TB-500?
TB-500 is a peptide based on a region of thymosin beta-4, a naturally occurring protein involved in cell migration and tissue organization. In community use it's most associated with recovery protocols. Because rigorous human data is limited, everything practical about it — dosing, timing, cycle length — circulates as anecdote, which is exactly why tracking your own response matters so much: your log is the only data that's actually about you.
Dosing patterns people discuss
TB-500 protocols are usually described in two phases:
- Loading phase: a higher weekly total (commonly cited around 2–5 mg/week, sometimes split into two injections) for roughly 4–6 weeks.
- Maintenance phase: a lower dose, often weekly or every couple of weeks, to maintain the effect.
These are not recommendations
The ranges above are anecdotal community figures included to explain how protocols are structured for tracking purposes. They are not medical advice or a suggested dose. Your provider is the right source for what — if anything — is appropriate for you.
Reconstituting TB-500
- Add bacteriostatic water slowly down the inside wall of the vial — don't spray it directly onto the powder.
- Let it dissolve on its own; swirl gently if needed, but don't shake.
- Calculate the draw: concentration = vial amount ÷ water added; draw volume = dose ÷ concentration; units = volume in mL × 100 on a U-100 insulin syringe.
- Save the numbers so every future dose is consistent.

Enter your vial amount, BAC water, and target dose into the free reconstitution calculator to get the exact draw in mL and insulin-syringe units.
How to track a TB-500 protocol
Because TB-500 is typically run in phases, the most useful thing you can do is keep your loading and maintenance doses clearly separated in time, so you can see which phase produced which result.
- Every dose: compound, amount (mg/mcg), units drawn, date/time, and injection site.
- The phase: note when you transition from loading to maintenance.
- Outcomes: rate recovery, mobility, joint comfort, and sleep on a simple scale.
- Objective metrics: where relevant, pair with weight, HRV, or sleep from a wearable.
- Inventory: track vial stock so a multi-week protocol doesn't stall on a missed reorder.
A peptide tracker app keeps all of this in one place. In LynkDose, every TB-500 dose is timestamped with its injection site, inventory ticks down automatically, and your recovery ratings and health metrics are charted against your dose history — so the difference between the loading and maintenance phases is something you can actually see.

LynkDose logs each dose, calculates reconstitution, tracks injection sites and inventory, and charts your recovery against your dose history — privately, on your iPhone.

TB-500 is discussed in phases, built on limited human data, and judged by subtle, cumulative effects — which makes a consistent log the only reliable way to evaluate it. Reconstitute carefully, log every dose with its phase and site, rate the outcomes you care about, and review the trend. That turns an expensive guess into something you can actually learn from.

Frequently asked questions
What is a common TB-500 dosage?
Anecdotal protocols often describe a loading phase of roughly 2–5 mg per week (sometimes split into two injections) for several weeks, followed by a lower maintenance dose. These are community figures, not medical recommendations — there is no established clinical dose for general use. Always consult a qualified healthcare provider.
How long is a typical TB-500 cycle?
Commonly discussed cycles run a 4–6 week loading phase followed by a maintenance phase or a break. The right structure depends on your goals and your provider's guidance; the constant is consistent tracking so you can actually evaluate the outcome.
How do I reconstitute TB-500?
Add bacteriostatic water slowly down the inside wall of the vial, let the powder dissolve without shaking, then calculate your draw: concentration = vial amount ÷ water added, and units = (dose ÷ concentration) × 100. A reconstitution calculator does the math instantly.
How should I track a TB-500 protocol?
Log each dose with the amount, units drawn, date, and injection site, distinguish loading from maintenance, and rate the outcomes you care about (recovery, mobility, comfort) over time. A peptide tracker app keeps doses, inventory, and trends together so you can judge whether the cycle is working.
