A standard TB-500 protocol consists of a 4-week loading phase at 4 to 10mg per week and a 2 to 4-week maintenance phase at 2 to 5mg per week.
Because of its long half-life, TB-500 only requires bi-weekly systemic injections, unlike daily localized peptides such as BPC-157.
Cycling off for at least 4 weeks is crucial to prevent receptor desensitization and maintain long-term efficacy of the peptide.
Peptides have moved from underground biohacker forums into mainstream wellness conversations. While GLP-1s normalized the category, regenerative peptides like TB-500 (Thymosin Beta-4) are now routine protocols for high-performers looking to accelerate tissue repair, reduce inflammation, and recover from injuries. But there is a massive execution gap. The actual user pain is not sourcing the peptide. The problem is execution. People forget doses, lose track of milligrams, and never log how they are feeling, so they cannot tell whether the protocol is actually working. This content is for informational purposes only and is not medical advice. Consult a healthcare provider for personalized recommendations. Peptides are not FDA-approved supplements, and legality varies by jurisdiction. If you and your clinician have decided to run a TB-500 protocol, the next step is managing the schedule. This guide breaks down the standard TB-500 protocol week by week and explains how miora creates a team of personal health agents to automate your tracking directly through iMessage.
When high-performing professionals and biohackers start a TB-500 protocol, they usually begin with a pristine spreadsheet. They map out their loading phase, calculate their reconstitution math, and plan their injection days. By week three, the spreadsheet is abandoned. Research shows that 95% of human behaviour is unconscious, and peptide adherence collapses without an external system. You forget whether you injected on Tuesday or Wednesday. You lose track of the exact milligram dosage. Most importantly, you fail to log your daily symptoms, making it impossible to objectively measure if your joint pain has decreased from a 7 to a 3.
This is where the shift from health tracking to health automation becomes critical. miora solves this by creating a team of personal health agents that live natively in iMessage and WhatsApp. Instead of opening a clunky app to log your protocol, miora acts as your executive health assistant. You simply text that you took 2.5mg of TB-500 sub-Q, and miora logs the dose, updates your protocol timeline, and sets the reminder for your next injection.
Furthermore, miora integrates with your entire health stack, including Apple Health, WHOOP, Oura, Garmin, and Google Calendar. It knows your sleep architecture and resting heart rate, allowing it to correlate your TB-500 cycle with actual physiological recovery data. If you are running a protocol to recover from a sports injury, miora can even automatically adjust your fitness schedule. It books lower-impact ClassPass or Barry's classes while you heal and orders macro-aligned meals via DoorDash to support tissue regeneration.
Before diving into the week-by-week schedule, it is crucial to understand why TB-500 is dosed the way it is. TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide that plays a vital role in cell migration, actin sequestration, and tissue repair. Unlike BPC-157, which has a very short half-life under 4 hours and requires daily or twice-daily dosing, TB-500 operates on a completely different timeframe.
Research indicates that TB-500 has a much longer systemic presence, with some pharmacokinetic models suggesting a half-life that allows for sustained therapeutic plasma levels over several days. Because of this extended half-life and tissue-level binding, daily dosing of TB-500 is generally considered unnecessary and can lead to cumulative plasma buildup without additional therapeutic benefits. Applying a daily dosing framework to TB-500 is a common mistake made by beginners who confuse it with other peptides.
Standard protocols across published literature and longevity clinics typically involve 2 to 3 injections per week during the loading phase, transitioning to 1 to 2 injections weekly for maintenance. The injections are usually administered subcutaneously into fatty tissue, such as the abdomen or thigh. Because TB-500 is systemic, it does not need to be injected directly adjacent to the site of injury. Managing this specific bi-weekly schedule is exactly why having an automated system is superior to relying on memory. Your miora health agent will text you on your specific injection days, ensuring you align perfectly with the peptide's pharmacokinetic profile.
The first four weeks of a TB-500 protocol are typically referred to as the loading phase. The goal during this period is to establish therapeutic levels of the peptide in the tissues to jumpstart the regenerative processes, upregulate cell-building proteins, and promote angiogenesis, which is the formation of new blood vessels.
During the loading phase, standard protocols often call for a total of 4mg to 10mg of TB-500 per week. Because of the peptide's half-life, this total weekly dose is usually split into two separate subcutaneous injections. For example, if your clinician recommends a 5mg weekly protocol, you would inject 2.5mg on Monday and 2.5mg on Thursday. Consistency is the most critical factor here. Missing doses or altering the schedule disrupts the steady-state concentration required for optimal tissue repair.
This is where miora's conversational interface becomes invaluable. Instead of setting easily ignored push notifications, miora sends you a natural text message reminding you of your 2.5mg TB-500 dose. After you reply that it is done, miora prompts a quick symptom check-in. It might ask you to rate your joint mobility, pain levels, or overall recovery on a scale of 1 to 5. Over these first four weeks, miora aggregates this data alongside your WHOOP or Oura recovery scores. By the end of week four, you do not have to guess if the protocol is working. miora provides a comprehensive weekly summary showing exactly how your subjective pain scores and objective biometric data have trended since day one.
Once the loading phase is complete and therapeutic tissue saturation has been achieved, most protocols transition into a maintenance phase for weeks 5 and 6. The objective here shifts from acute intervention to supporting ongoing regenerative processes and maintaining the healing momentum without overstimulating the cellular receptors.
During the maintenance phase, the total weekly dosage is typically reduced by half. A common maintenance protocol involves 2mg to 5mg per week, often administered as a single injection or split into two smaller doses. For instance, a user who was taking 5mg a week during the loading phase might drop to 2.5mg once a week during maintenance. This reduction helps mitigate the risk of receptor desensitization while still providing enough of the peptide to support continued tissue repair and inflammation reduction.
Transitioning between phases is a common point of failure for self-managed protocols. People forget to lower their dose or lose track of which week they are on. When your protocol is built into miora, your team of health agents handles the transition automatically. On the first day of week 5, miora will text you with your updated, lower dosage requirement. Furthermore, miora continues to monitor your daily symptom logs. If your pain scores begin to rise again during the maintenance phase, miora's weekly aggregation will highlight this trend, giving you and your healthcare provider clear data to decide whether the maintenance dose needs adjustment or if the cycle should be concluded.
Peptide cycling is a fundamental concept in longevity and biohacking protocols. Just as insulin receptors can become resistant with constant exposure to high glucose, peptide receptors can downregulate if continuously stimulated. Angiogenesis peptides like TB-500 stimulate new blood vessel growth and cellular migration, which are powerful mechanisms for tissue repair but processes that should not be forced indefinitely.
After 4 to 6 weeks of active use, standard protocols mandate an off-cycle, typically lasting 4 weeks or more. During this rest period, the body is allowed to clear the exogenous peptide, and cellular receptors resensitize. It is important to note that the healing initiated by TB-500 does not immediately stop when the injections cease. The tissue repair and extracellular matrix remodeling continue during the off-cycle.
Tracking the off-cycle is just as important as tracking the active injections. Many users forget when their off-cycle ends and either restart too early or abandon the protocol entirely. miora acts as your protocol memory. It logs the exact date your cycle ended and schedules a reminder for when you are cleared to begin a new cycle, if necessary. During these off weeks, miora continues to prompt your daily symptom check-ins via WhatsApp or iMessage. This allows you to monitor if your baseline pain or mobility remains stable without the peptide, which is the ultimate indicator of a successful healing protocol. If your WHOOP or Garmin data shows sustained high HRV and recovery scores during the off-cycle, you have objective proof of the protocol's efficacy.
In the biohacking and sports recovery communities, TB-500 is rarely used in isolation. It is most commonly stacked with BPC-157, a combination often colloquially referred to as the Wolverine Stack. The rationale behind this combination is synergy, as they work through complementary mechanisms. TB-500 provides systemic anti-inflammatory effects and promotes cellular migration, while BPC-157 promotes localized angiogenesis and upregulates growth factor receptors near the site of injury. While BPC-157 focuses on building the new blood vessels needed for repair, TB-500 acts as the project manager, signaling cells to move to the site of damage to begin reconstruction. This dual-action approach is designed to accelerate the healing of connective tissues, tendons, and ligaments more effectively than either peptide alone.
However, stacking peptides introduces significant logistical complexity that often leads to protocol failure. BPC-157 has a very short half-life and typically requires daily or twice-daily injections, often localized near the injury site. TB-500 requires bi-weekly systemic injections. Managing a schedule where you inject BPC-157 every morning and evening, but only add TB-500 on Monday and Thursday mornings, is a recipe for missed doses and dosage errors. For a standard eight-week cycle, you are looking at over 120 individual actions to track and execute. This mental load is where most people give up on their recovery goals, as the friction of management outweighs the desire for results.
This is the exact scenario where miora's health automation outshines manual tracking. You can input your entire complex stack into the miora protocol engine, and your personal health agent takes over the logistics. The benefits of this automation include:
Precision Timing: Your personal health agent will text you via iMessage or WhatsApp at your preferred times, reminding you of your 250mcg BPC-157 local dose and your 2.5mg TB-500 systemic dose.
Contextual Awareness: If your WHOOP, Oura, or Garmin data shows a significant dip in recovery or an increase in resting heart rate, miora can prompt you to log any site-specific soreness or side effects to keep your protocol on track.
Zero Cognitive Load: By offloading the schedule management to an AI assistant, you achieve consistency without willpower. You stop deciding and calculating, and start executing.
miora holds the schedule, the milligrams, and the symptom log, ensuring your complex stack is administered flawlessly. While you should always consult a healthcare provider before starting any peptide protocol, miora ensures that once a plan is set, it is followed to the letter. This level of optimization was once reserved for elite athletes with full-time medical staffs, but miora makes it accessible to everyone. You no longer need to be a spreadsheet expert to manage a sophisticated recovery protocol. You simply respond to a text, confirm your dose, and let your team of agents handle the rest.
The fundamental problem with modern health optimization is that we have maximized our data but failed to improve our execution. Your WHOOP tells you your recovery is 30 percent. Your Apple Health logs your sleep debt. Your spreadsheet holds your TB-500 protocol. But none of these tools actually take action. They are passive trackers. miora represents a paradigm shift from health tracking to health automation by creating a team of personal health agents that take action on your behalf.
Imagine a scenario where you are running a TB-500 protocol for a shoulder injury. miora knows your injection schedule and logs your daily pain scores via iMessage. But it goes much further. Because miora integrates with your Google Calendar, ClassPass, and Barry's accounts, it can actively manage your fitness routine. If your WHOOP data shows poor recovery and your daily symptom log indicates increased shoulder pain, miora will automatically cancel your heavy lifting session and book a restorative yoga class on ClassPass instead.
Furthermore, miora handles your nutrition. Tissue repair requires adequate protein and micronutrients. Based on your goals and daily protocols, miora can automatically order a macro-aligned meal via DoorDash to ensure you hit your 1.8g/kg protein target without having to think about meal prep. It can even order an Uber or Waymo to get you to your recovery class. This is what it means to put your health on autopilot. You get Bryan Johnson-level optimization, where every meal, workout, and protocol is perfectly orchestrated, without needing a personal staff.
As longevity clinics and telehealth platforms continue to expand access to therapeutic peptides, the bottleneck will no longer be access to compounds. It will be patient adherence. Clinics already report that patient compliance is their number one unsolved problem. Patients drop off, forget their doses, and fail to report side effects or improvements.
miora bridges the gap between the clinician's prescription and the patient's daily reality. Because miora is conversational-first, it removes the friction of traditional app interfaces. There is no portal to log into, no clunky UI to navigate. Your health agent simply texts you on WhatsApp or iMessage, the platforms where you already spend your time. This conversational interface allows for nuanced symptom logging. You can text that your knee feels a bit stiff today, maybe a 4 out of 10, but your sleep was great, and miora's AI extracts the relevant data points to update your protocol history.
Ultimately, whether you are running a TB-500 protocol for an acute injury, optimizing your macros for a looksmaxxing routine, or trying to balance a demanding executive schedule with a biohacking lifestyle, the goal is the same. The goal is consistency. Willpower is a finite resource that depletes throughout the day. By delegating the logistics of your health to miora's team of agents, you preserve your mental energy for your actual life. Stop deciding what to eat, when to train, and when to inject. Let miora handle the execution, so you can focus on the results.
