Stiff or sore in more than one place?A doctor can check if TB4 may help your body repair all of them.
TB4 is thymosin beta-4, a repair protein your body already makes to move repair cells to where they are needed. Clarve’s TB4 is the whole protein, all 43 parts, not the short 7-part piece sold online as TB-500. New to peptides? Read what they are first.

The doctor decides if it suits you
If it does, our own licensed pharmacy makes your pen and keeps it cold all the way to your door.
What the doctor actually asks you on the call. It is a normal doctor consultation, not a sales call. Expect the doctor to go through your answers and your health history, and to decide whether a peptide is safe and right for you.
Then the doctor tells you whether a peptide suits you at all. If it does not, they say so and tell you why. Nothing is prescribed, and you pay nothing more than the R99.
A muscle or tendon that stays sore for months is tissue that never finished repairing itself. TB4 may help move those cells to where you hurt.
When you are sore in more than one place, repair cells need to reach every one of those spots. Your body makes thymosin beta-4 in almost every tissue, not just at one injury, which is why a doctor may look at TB4 when more than one place is sore.
- It may help move repair cells to the parts of your body that hurt.
- It may help your body grow new, tiny blood vessels, bringing more oxygen and nutrients to damaged tissue.
- It may help damaged muscle and tendon tissue repair itself.
Clarve makes TB4 in our own licensed pharmacy in Johannesburg, from pharmaceutical-grade ingredients that are lab-tested to be at least 98% pure.
Why your shoulders, your back and your knees can all ache at the same time, and how TB4 may help your body repair all of them.
One sore tendon is one place your body has to repair. A sore shoulder, a sore lower back and a sore knee are three places at once, and every one of them is waiting for the same thing: repair cells that have to travel there through your blood.
Your body repairs damage by sending cells to it. They travel in your blood, they arrive at the damaged tissue, and they do the work. That is true of a strained tendon, a torn muscle and a cut on your arm.
Now picture three sore places at once. Each one needs those repair cells to arrive, and to stay long enough to finish the job. So a body that aches in several places is not one injury that got worse. It is three separate places your body is trying to repair at the same time, and repair cells have to reach every one of them.

When more than one part of you is sore, your own repair cells have to reach every one of those places. TB4 may help move them to where you hurt.
This is where TB4 comes in. TB4 is thymosin beta-4, a repair protein your body already makes, in almost every tissue you have, not only at one injury.
A repair cell does not float to the damage. It crawls, by building a stiff scaffolding inside itself and pushing its front edge forward. Thymosin beta-4 holds the spare building blocks that scaffolding is made from, and lets them go at the front edge, exactly where the cell needs to build. Without them the cell cannot move.

A repair cell moves by building a scaffolding inside itself and pushing its front edge forward. TB4 is part of how your body controls the building blocks that scaffolding is made from.
So why a pen, and not a pill? A peptide is a chain of amino acids, and thymosin beta-4 is a long one, 43 links. Most peptides are broken apart by your stomach before your body can use them, which is why they are injected under the skin instead of swallowed.
A small injection skips your stomach, so the chain arrives whole and your doctor knows exactly what reached you and how much. That is why Clarve makes TB4 as a ready-to-use pen, never as a capsule, spray or cream.

Most peptides are broken apart by your stomach before your body can use them, which is why they are injected under the skin instead of swallowed.
TB4 may also help your body grow new, tiny blood vessels, which is how more oxygen and nutrients reach tissue that is under strain.
What is sold online as TB-500 is not the whole protein. It is a short, 7-part piece of thymosin beta-4. Clarve’s TB4 is the whole protein, all 43 parts.
What it is not: a painkiller, and not a guarantee. A registered doctor decides whether it suits you at all, and tells you straight if it does not.
TB4 is not for you if one of these is true.
- You have an active or recent cancer diagnosis, and no clearance from your specialist
- You are pregnant or breastfeeding
- You are an athlete who gets drug-tested for your sport
Like any medicine, TB4 is not right for everyone. That is why a registered doctor reads your health history before anything is prescribed.
TB4 bought without a prescription has no doctor and no lab test behind it.
Most people in South Africa get peptides from someone at the gym, a friend or a seller on WhatsApp. Nobody checks what is inside, or whether it suits them. Compare that with a doctor and a licensed pharmacy.

One sore spot, or several? Your doctor decides which peptide fits you.
As a general guide, people ask about BPC-157 when one spot is sore, and about TB4 when several places are sore. Some people use both together.

BPC-157 is used for pain in one place. TB4 is used more widely when several places are sore. Your doctor decides which one fits you, or whether you need both.

TB4
Used across the whole body
Your body makes thymosin beta-4 in almost every tissue, not just at one spot. It may help move repair cells to where they are needed, in more than one place at a time.
Used for one sore spot
BPC-157
Used for one problem area, such as a tendon, a ligament, a muscle or the gut. It may help your body repair the damage right where it hurts.
Read about BPC-157Why some people use both: the Wolverine Stack
TB4 may help all over your body, while BPC-157 may help at the injury itself. Your doctor decides at the R99 consult whether you need both or whether one is enough.
R99 is the consult, not the medicine
Find out if a doctor thinks TB4 could help your body recover.
Pay a once-off R99 to speak to a registered doctor, who decides whether TB4 suits you. If the doctor says this therapy isn’t right for you, they will tell you exactly why. You pay nothing more.
