About this peptide
TB-500 is a recovery research peptide based on the active region of thymosin beta-4, a natural repair protein. It is often researched alongside BPC-157 for systemic recovery. Most of the published science studies the full parent protein rather than the fragment, and human data are limited, so it is best treated as promising but not proven. Supplied as a freeze-dried powder for research use.
What it does
Researched for recovery, flexibility and whole-body tissue repair, and it is the systemic counterpart to BPC-157's more localised reputation, which is why the two are so often run together. Bodybuilders and strength athletes explore it for nagging soft-tissue injuries, joint and tendon comfort and a sense of improved range of motion; the recovery crowd runs it in healing phases between hard training blocks. Studied as a repair compound, not for muscle growth or performance.
What to expect
Week 1
No self-reported benefit; mild head-pressure/lethargy and injection-site reactions reported (community)
Weeks 2-4
Anecdotal joint/tendon improvement; loading phase
Weeks 4-12
Maintenance; gains tend to plateau; stacked BPC-157 effects reported additive
Long term
No published human chronic-dosing data; community cycles 8 on / 4-8 off

Key points
A common pick for people researching recovery who want a systemic partner to BPC-157, and the BPC and TB pairing (our BPC + TB Blend) is one of the most-run recovery stacks in the space. Best suited to those comfortable that the strongest published evidence concerns the full thymosin beta-4 protein rather than the TB-500 fragment itself. Not aimed at muscle growth or performance.
TB-500 corresponds to the actin-binding region of thymosin beta-4. Research on that protein describes roles in cell migration, new blood-vessel formation and wound healing, which is the basis for interest in the fragment for whole-body recovery research.
Most evidence applies to the parent protein and is largely preclinical, so human effects and long-term safety are not established. Because it supports new blood-vessel growth, reviews note the same caution as other blood-vessel-growth peptides where an existing tumour may be present. Purity and correct reconstitution matter, and a Certificate of Analysis is shared where our supplier provides one.
Supplied freeze-dried. Reconstitute with bacteriostatic water to your required concentration, then refrigerate at 2-8°C; swirl gently rather than shake. We can reconstitute to spec for you as a paid service.

Questions about TB-500
Not quite. TB-500 corresponds to the active region of thymosin beta-4. Most research is on the full protein, so we are careful to distinguish the two.
It is limited. Most studies are preclinical and use the parent protein, so we describe what the research covers rather than imply proven human effects.
