Wound healing
Applied to the skin or injected, thymosin beta-4 increased skin regeneration by 42% at 4 days and by up to 61% at 7 days, compared with saline.
Treated wounds showed more collagen and more new blood vessels.
Synthetic thymosin beta-4, studied for tissue and wound repair.
Purity 99.116% verified by Janoshik. Lot TB10261110K.





TB-500 is the synthetic version of thymosin beta-4, a 43-amino-acid protein found in almost every cell in the body. Janoshik's analysis confirms our vials contain the full protein, not a fragment.
It's studied for wound healing, muscle recovery and the formation of blood vessels. Most of the research is in animals.
Thymosin beta-4 binds to actin, the protein that gives cells their shape and lets them move. In the lab it helps cells reach the damaged area and helps new blood vessels form.
The analysis of the lot we're selling today, done by Janoshik, an independent lab.

Janoshik analyzed a sample from lot TB10261110K. The result applies to that sample, not to every vial in the lot.
Reconstituting means mixing the powder in the vial with bacteriostatic water to get a solution that's ready to use. The peptide comes as a powder because it keeps better that way.
The same 6 steps as the video. Tap an image to see it full size.
Afterward: label the vial with the date you reconstituted it and keep it in the fridge (see Storage).
Once reconstituted, it needs cold and darkness.
This is a suggested progression, not a cycle you have to finish. Go up slowly; you can stay at any phase. It's the reference published by peptidedosages.com; no human trial has defined a dose of TB-500.

If you feel good at one phase, you don't need to move to the next. The table is a guide, not a goal.
The 0.5 mL syringe has one line per unit. Look at the mark at eye level, at the edge of the plunger closest to the needle.
Write down each week how the area you care about feels. If there are changes, they don't show from one day to the next.
Some people mention it in the first few days. Taking it at night may help.
Rotate between belly and thighs, and leave a few inches between one injection and the next.
Stay on your current dose longer, or stop. You can pick it back up whenever you want.
They're different molecules. In forums, BPC-157 is associated with a specific area (a tendon, the stomach) and TB-500 with the body's overall recovery. Many people combine them, although there are no studies of the two together.
Yes. KAILAB's TB-500 is full thymosin beta-4, 43 amino acids long, according to Janoshik's analysis. Some sellers use the same name for a 7-amino-acid fragment; they're different molecules, so it's worth checking the certificate.
In forums it's common to take it twice a week at higher doses. We follow the peptidedosages.com reference, which uses a smaller daily dose so measuring is easy and consistent.
In Quality, on this same page, you can open the report for the strength and lot we sell.
Every peptide vial comes with one 3 mL vial of bacteriostatic water, plus alcohol wipes; the reconstitution guide is on this page. Shipping is free anywhere in Colombia, in discreet packaging.
If your payment is confirmed before 4 p.m. (Monday to Friday) or noon (Saturday), we ship it that same day. After that time, and on Sundays and Colombian holidays, we ship it the next business day. Bogotá time.

Most of the data are for full thymosin beta-4, in animals and in a few small human trials.
Applied to the skin or injected, thymosin beta-4 increased skin regeneration by 42% at 4 days and by up to 61% at 7 days, compared with saline.
Treated wounds showed more collagen and more new blood vessels.
With 0.1% thymosin beta-4 drops, discomfort in a dry-environment test dropped 27% versus placebo on day 28. The study's two primary endpoints showed no difference.
No adverse effects were reported. It was given as eye drops, not injected.
