BPC-157 + TB-500 20 mg — Quick Chart
Dosing & Reconstitution Overview
This blend pairs BPC-157, a 15-amino-acid fragment derived from a protein found in gastric juice, with TB-500, a synthetic version of the active region of thymosin beta-4. The two are co-formulated in a single lyophilized vial holding 20 mg of total material — split evenly as 10 mg of BPC-157 and 10 mg of TB-500. The figures below are compiled strictly for laboratory and educational reference; they describe how the combination is handled and measured, not a recommendation for use in humans or animals.
For a 20 mg vial, adding 3.0 mL of bacteriostatic water yields a total concentration of ~6.67 mg/mL, which works out to roughly 3.33 mg/mL of each peptide. At that fill, a 0.10 mL draw on a U-100 insulin syringe equals 10 units and delivers about 667 mcg of blend (≈333 mcg of each compound), so the per-unit math stays consistent across the titration steps below.
Standard (Gradual) Titration Schedule
The gradual schedule starts low and steps the daily amount upward over several weeks, giving a slow ramp that many reference protocols favour for tolerability when modelling once-daily subcutaneous administration.
| Phase | Daily Dose (total) | Per Peptide | Units (U-100) | Volume |
|---|---|---|---|---|
| Weeks 1–2 | 500 mcg (0.5 mg) | ≈ 250 mcg each | 7.5 units | 0.075 mL |
| Weeks 3–4 | 666 mcg (0.67 mg) | ≈ 333 mcg each | 10 units | 0.10 mL |
| Weeks 5–8 | 1000 mcg (1.0 mg) | ≈ 500 mcg each | 15 units | 0.15 mL |
Reconstitution Steps
- Let the sealed lyophilized vial and the bacteriostatic water reach room temperature, then wipe both stoppers with an alcohol swab.
- Draw 3.0 mL of bacteriostatic water and inject it slowly down the inside wall of the vial — never directly onto the powder pellet.
- Swirl gently until both peptides fully dissolve. Do not shake; vigorous agitation can damage the peptide chains.
- The finished solution should be clear and colourless. Label the vial with the total concentration (~6.67 mg/mL) and the reconstitution date.
- Store upright under refrigeration between uses and draw each subsequent volume with a fresh sterile syringe.
Advanced (Loading) Schedule
The advanced approach front-loads a higher daily amount for the first four weeks before dropping to a maintenance level. It reaches the top of the typical range at the loading step and is sometimes referenced where a faster cumulative exposure is being modelled.
| Phase | Daily Dose (total) | Per Peptide | Units (U-100) | Volume |
|---|---|---|---|---|
| Loading (Weeks 1–4) | 1500 mcg (1.5 mg) | ≈ 750 mcg each | 22.5 units | 0.225 mL |
| Maintenance (Weeks 5–8) | 1000 mcg (1.0 mg) | ≈ 500 mcg each | 15 units | 0.15 mL |
1500 mcg total per day (≈750 mcg of each peptide) sits at the upper edge of the commonly referenced range for this blend. The loading-then-maintenance pattern simply shifts more of the cumulative dose into the first month rather than spreading it evenly.
Supplies Needed
- Blend vials (20 mg): ~2 vials for a 4-week run; ~3 vials for 6 weeks; ~3–4 vials for 8 weeks.
- Insulin syringes (U-100, 1 mL): 28 for 4 weeks, 42 for 6 weeks, 56 for 8 weeks (one fresh syringe per daily draw).
- Bacteriostatic water (10 mL): one bottle covers a 4–6 week run; two bottles for an 8-week schedule.
- Alcohol swabs: a single 100-count box covers 4–6 weeks; two boxes for 8 weeks.
Protocol Overview
- Research goal: model combined cytoprotective and tissue-repair signalling from a BPC-157 / TB-500 pairing.
- Schedule: once-daily subcutaneous administration in the referenced model.
- Dose band: 500–1500 mcg total blend daily (≈250–750 mcg of each peptide).
- Fill: 20 mg lyophilized (10 mg + 10 mg), reconstituted to ~6.67 mg/mL with 3 mL diluent.
- Storage: −20 °C dry; 2–8 °C once reconstituted.
Dosing Protocol Notes
- Begin at the lowest 500 mcg step and hold each level for one to two weeks before stepping up.
- Keep administration on a fixed daily cadence and ideally the same time of day for steady exposure modelling.
- Escalate only after the prior step has been tolerated.
- Most referenced runs sit in the 4–8 week window before pausing to reassess.
Storage Instructions
Keep sealed lyophilized vials at −20 °C, protected from light, where the dry powder stays stable for many months. Once reconstituted, refrigerate at 2–8 °C and use within about 14 days. Allow refrigerated solution to warm slightly before drawing, avoid repeated freeze-thaw cycles, and aliquot if a vial will be sampled many times.
Important Handling Notes
- Use a sterile syringe for every draw and never re-enter the vial with a used needle.
- Rotate handling technique to keep the rubber stopper intact across many punctures.
- Because both peptides share the vial, draw the full daily volume in one pull to keep the split even.
- Document each draw — date, volume, remaining material — for reproducibility.
How It Works
BPC-157 is a stable 15-amino-acid pentadecapeptide fragment isolated from a protein in gastric juice. In preclinical work it has been studied for cytoprotective and tissue-repair activity spanning the gastrointestinal tract, tendons and other musculoskeletal tissue, and the nervous system, with proposed effects on blood-vessel formation. TB-500 is the synthetic active fragment of thymosin beta-4, a 43-amino-acid peptide tied to cell migration, angiogenesis and wound healing. The rationale for pairing them is that their reported repair mechanisms are studied as complementary — BPC-157 leaning toward localized protection and TB-500 toward broader cell-migration and vascular processes.
Reported Benefits & Side Effects
Benefits reported in research
- Wound healing and tendon-repair signalling in preclinical models.
- Anti-inflammatory activity across several tissue types.
- Gastroprotective and ulcer-healing effects attributed mainly to BPC-157.
- A wide safety margin in the available animal studies.
Side effects reported
- Occasional mild injection-site reactions such as redness or itching.
- Rare, transient dizziness or nausea in scattered reports.
- Long-term controlled human safety data remain limited for both compounds.
Injection/Handling Technique (Reference Only)
- Clean the vial stopper and the handling site with alcohol and let both dry.
- Insert subcutaneously at a 45–90° angle using a fine needle (23–25 gauge, 5/8″); aspiration is not required for subcutaneous work.
- Inject slowly and steadily; rotate sites systematically across the abdomen, lateral thigh, upper arm and other approved areas.
- Where a localized site is being modelled, subcutaneous placement near the target area is sometimes referenced when anatomically appropriate.
- Dispose of sharps in an approved container.
