Calculate TB-500 doses for loading and maintenance phases

TB-500 (Thymosin Beta-4) uses different dosing than most peptides. Instead of daily micrograms, you take milligrams weekly. Loading phase: 5-10mg twice weekly for 4 weeks. Maintenance: 2-5mg once weekly.

This calculator shows your weekly dose, injection volume based on concentration, and total vials needed for complete loading + maintenance protocol.

Standard TB-500 protocol:

Loading phase (Weeks 1-4):

• 5mg twice weekly (Monday/Thursday)

• Total per week: 10mg

• Total for loading: 40mg (8 vials of 5mg)

Maintenance phase (Weeks 5-12):

• 2-5mg once weekly

• Total per week: 2-5mg

• Total for maintenance: 16-40mg (3-8 vials)

Example: 5mg vial + 2ml water = 2,500mcg/ml

• 5mg dose (5,000mcg) = draw 2.0ml (full vial)

• 2.5mg dose = draw 1.0ml

TB-500 doses are MUCH larger than BPC-157. You're often injecting 1-2ml, not 0.1-0.2ml.

Loading vs maintenance dosing protocols

Loading phase dosing (Weeks 1-4):

Why loading exists:

• Saturates tissue quickly

• Builds therapeutic levels fast

• Front-loads healing response

• Essential for good results

Standard loading:

• 5mg twice weekly (10mg/week total)

• Days: Monday and Thursday (or Tuesday/Friday)

• 3-4 days between injections

• 4 weeks = 40mg total needed

Aggressive loading (serious injuries):

• 7.5-10mg twice weekly (15-20mg/week)

• Used by athletes with major injuries

• Expensive but faster results

• 4 weeks = 60-80mg total

Conservative loading (budget/prevention):

• 2.5mg twice weekly (5mg/week)

• Slower tissue saturation

• Takes longer to see results

• 4 weeks = 20mg total

Maintenance phase dosing (Weeks 5+):

Standard maintenance:

• 2-5mg once weekly

• Most use 2.5mg weekly

• Sustains therapeutic levels

• Continue 4-8 weeks after loading

Why maintenance matters:

• Loading alone insufficient for deep healing

• Maintenance consolidates gains

• Prevents reinjury

• Keeps inflammation down

Duration of maintenance:

• Minimum: 4 weeks

• Standard: 8 weeks

• Extended: 12+ weeks for chronic issues

Total protocol examples:

Standard 12-week protocol:

• Weeks 1-4: 5mg twice weekly = 40mg

• Weeks 5-12: 2.5mg once weekly = 20mg

• Total needed: 60mg (12 vials of 5mg)

• Cost: $540-$720

Aggressive 8-week protocol:

• Weeks 1-4: 7.5mg twice weekly = 60mg

• Weeks 5-8: 5mg once weekly = 20mg

• Total needed: 80mg (16 vials)

• Cost: $720-$960
