HOW MUCH YOU’LL NEED

SUGGESTED ORDER AMOUNT

At a standard dose of 5mg twice per week, one 10mg vial lasts approximately 1 week. A common approach is 6 vials per person for a standard loading phase, with 10–12 vials covering a full 12-week loading and maintenance cycle.

Dosage (Male)

5-20mg per week

Dosage (Female)

1-10mg per week

Dosage Frequency

Dosage Type

Subcutaneous or Intramuscular Injection

MIXING & Usage Guidelines

01

Draw 1.0 mL of Bacteriostatic Water USP from the vial.

02

Carefully inject the Bacteriostatic Water into the TB-500 vial, aiming the stream along the side of the vial and avoiding direct contact with the lyophilized powder.

03

Gently swirl the vial until the powder is fully dissolved and the solution becomes clear. Do not shake the vial vigorously.

04

Once mixed, the concentration will be 10mg per mL (10mg per 1mL vial), equating to 1mg per 10 units on a standard insulin syringe. Remember, 100 units on the syringe equals 1mL, corresponding to the full 10mg dose.

05

The prepared solution can be administered subcutaneously (SubQ) in the lower abdominal fat area. TB-500 travels systemically through the bloodstream to find and repair damaged tissue anywhere in the body — site-specific injection is not required.

06

Once reconstituted with Bacteriostatic Water, store the vial in the refrigerator. Use within 60 days to ensure potency and effectiveness.

WHEN TO TAKE it

TB-500 is typically administered twice per week. While timing is flexible, many users favour evening dosing to align with the body’s natural tissue repair and cellular migration processes that peak during sleep. Due to its long half-life and systemic action, it can be taken any time of day that ensures consistency.

TB-500 works best with a loading and maintenance strategy to saturate the tissues — a higher-frequency loading phase followed by a reduced maintenance dose helps establish and sustain the regenerative environment needed for meaningful connective tissue repair.

Connective tissue repairs slowly — consistency over a full 6–12 week protocol often yields the best structural results. You do not need to inject near the site of injury, as TB-500 travels through the bloodstream to find damaged tissue wherever it is in the body.

RECOMMENDED SCHEDULE

Maintenance Dose (2.5mg — 25 units, twice per week): Ideal for ongoing joint health, flexibility, and injury prevention
Standard Dose (5mg — 50 units, twice per week): The most common dose for muscle tears, tendonitis, or ligament strain recovery
Loading Dose (10mg per week — 50 units twice per week): For rapid tissue saturation following a fresh injury or surgery during weeks 1–4
Loading Phase (Weeks 1–4): 5–10mg per week split into two injections (e.g., Monday and Thursday)
Maintenance Phase (Weeks 5+): 2.5–5mg once per week
Cycle Length: 6–12 weeks for best structural results

Consult With a Healthcare Provider

Before considering the use of peptides, it’s important to speak with a licensed medical professional. They can assess your overall health, explain the potential benefits and risks, and provide tailored advice that fits your personal goals and medical history.

Choose Reputable, Quality Sources

To minimize the risk of contaminated or counterfeit products, source peptides from reputable vendors like Pacific Peptides. Choose trusted suppliers with strict quality standards and a proven track record in the fitness or medical community. You can also check out reviews from our trusted customers to make an informed decision.

Begin
Conservatively

When starting peptides, begin with the lowest dose that may offer results. Increase gradually only if necessary, paying close attention to how your body responds and watching for any unwanted effects along the way.

PRIORITISE RECOVERY & MONITORING

Peptide protocols should be supported by proper recovery and regular self monitoring. Prioritizing sleep, nutrition, hydration, and stress management helps maximize results while reducing the risk of unwanted effects. Allowing adequate time between cycles supports long term metabolic health and overall well being.

Increased Strength & Power

TB-500, a naturally occurring peptide with powerful regenerative properties, supports strength development by directly targeting skeletal and cardiac muscles. Studies suggest it can boost red blood cell production and enhance muscle endurance, leading to noticeable improvements in strength and overall performance.

Better Muscular Endurance

This peptide works by stimulating the growth of essential cells that support and maintain muscle tissue. It also aids in the production of proteins that regulate immune function, reduce inflammation, and facilitate cell repair, making it a valuable tool for enhancing endurance.

Faster Recovery & Repair

TB-500 accelerates the healing process by boosting collagen production, which improves joint flexibility and overall tissue resilience. This makes it especially beneficial for athletes, helping to reduce post-exercise fatigue and shorten recovery times.

Inflammation Control

Unlike many conventional treatments, TB-500 effectively targets inflammation at the cellular level without causing unwanted side effects. Its unique ability to modulate immune responses makes it a promising option for managing various inflammatory conditions.

Incorporate TB-500 Into a Stack

Bodybuilders often opt for a combination of diverse peptides to augment their muscle growth and advancement, in conjunction with TB-500. Our preferred peptide to pair with TB-500 is unquestionably BPC-157. The synergy of these two peptides accelerates the healing process, providing the optimal benefits. Initially, TB-500 functions as the synthetic counterpart to a region predominantly active in Thymosin Beta 4. Its role in promoting healing involves facilitating the production of new blood vessels and muscle tissue, achieved through the upregulation of actin and other proteins essential for cell building. When considering the coupling with BPC-157, the emphasis shifts towards the healing of soft tissue injuries, particularly in areas such as tendons and ligaments. Further, we advocate the combination of TB-500 with IGF-1 LR3. These compounds collectively contribute to enhanced healing, recovery, and superior muscle growth when utilized consistently over time.
