TB500 (5 mg) OxyPharma is a synthetic analogue of thymosin beta-4, a peptide found naturally in human and animal cells. The Indian-made OxyPharma version has earned a steady following in training circles for one simple reason: sensible pricing paired with reliable quality. Each 5 mg ampoule is supplied ready for reconstitution, with home delivery on offer, so there is no need to collect the order in person. A peptide aimed at performance recovery. OxyPharma developed TB500 with athletes in mind — those chasing speed, strength and sustainable endurance. The compound works on several fronts at once: it supports muscle growth; sharpens speed and strength output; eases spasm and tones the fibres; dampens inflammation in ligaments and joints; promotes flexibility; lowers the risk of myocardial infarction; and encourages the growth of new blood vessels within muscle tissue. And although TB500 clearly lifts performance, it has not been added to the banned list — the body already produces thymosin beta-4 on its own. For athletes coming back from injury, that endogenous match is a real advantage. Regeneration improves, healing speeds up, and training sessions start to feel less like damage control. Lifters pushing high-volume blocks also tend to find it useful for shaking off the muscle cramps that stall progress. Directions for use. Each OxyPharma ampoule holds 5 mg of thymosin beta-4, prepared for injection the usual way for peptides — reconstituted with water. A full course runs two to three months. Dosage is tailored to the athlete’s condition, body weight and other individual factors. During the first four weeks TB500 is given two to three times a week, with a weekly total of 2 to 6 mg. After that, 2 to 4 mg is run on the same pattern for a further 4–8 weeks. A different protocol is sometimes used instead: 10 mg across 7 days, with no split between a loading and a maintenance phase. Side effects. These are uncommon with OxyPharma TB500. If anything feels off once the course begins, it is worth consulting a doctor who can either adjust the dose or recommend an alternative. Thymosin is contraindicated in children and adolescents. The product is sold in 5 mg packaging and listed under the Peptides category: TB500 (5 mg) OxyPharma.

TB500 (5 mg) OxyPharma — product information
Thymosin beta 4 is a synthetic analogue of a peptide that occurs naturally in animal and human cells. The TB500 (5 mg) product from the Indian brand OxyPharma combines a sensible price with reliable quality — largely why many bodybuilders tend to pick it up.
A peptide drug built for performance
OxyPharma developed the TB500 peptide with athletes in mind — specifically those pursuing speed-strength and endurance improvements. The drug produces a layered effect:
stimulates muscle growth;
improves speed and strength indicators;
reduces spasms and tones the muscles;
addresses inflammatory processes in ligaments and joints;
supports greater flexibility;
reduces the risk of myocardial infarction;
accelerates the growth of new blood vessels in muscle tissue.
Although the compound noticeably lifts performance, it hasn’t been added to the list of prohibited substances — the body produces it naturally.
TB500 from OxyPharma also comes into play during recovery from injury. It supports regeneration processes and shortens healing times. The TB500 peptide is similarly useful for athletes training intensively who want to clear muscle spasms and squeeze more output from each session.
Directions for use
Each TB500 OxyPharma ampoule holds 5 mg of thymosin beta 4. Preparation for injection follows the standard peptide method — dilution with water. Course duration runs from two to three months. Dose selection depends on the athlete’s level of conditioning, body weight and other individual traits.
In the first four weeks, TB500 is administered two or three times per week, with total dosing in the 2 to 6 mg range. After that, 2 to 4 mg is used on the same schedule across 4-8 weeks. Sometimes a different protocol applies: 10 mg across 7 days, without splitting into loading and maintenance phases. Protocol choice tends to follow the training phase — rehab-focused blocks differ from pure performance blocks.
Side effects while using TB500 from OxyPharma are rare. Anyone noticing a change in condition after starting the course should consult a doctor — who may adjust the dose or recommend a different compound. Use of thymosin is contraindicated in children and adolescents.

TB-500 (Thymosin Beta-4) is a systemic repair peptide, acting through actin regulation to drive angiogenesis and cell migration. The 5 mg vial suits a short loading phase — 2.5 mg twice weekly for two weeks — followed by maintenance dosing at around 2 mg weekly. Reconstitute with 1–2 ml bacteriostatic water. Sub-cut injection in the abdomen or thigh works; the peptide circulates systemically regardless of local site. Keep refrigerated. Pairs commonly with BPC-157 when the goal is tendon or ligament recovery alongside systemic resilience.

Thymosin Beta-4 fragment — commonly sold as TB-500 — in a 5 mg lyophilised vial.
Repair protocols generally start with a four-to-six week loading phase at 2–5 mg weekly, split across two sub-cut shots, before dropping to a maintenance dose. The peptide drives actin polymerisation and encourages cell migration into injured tissue. Favoured by athletes rehabilitating tendon strains, muscle tears or stubborn joint flare-ups.
Frequently Asked Questions
What is TB-500 and what does it do?
TB-500 is a synthetic version of Thymosin Beta-4, a peptide involved in tissue repair, angiogenesis and cell migration. Weekly doses sit at 2–5 mg.
How long does a typical TB-500 cycle run?
TB-500 is a synthetic version of Thymosin Beta-4. A standard protocol sits around 2–5 mg weekly, split into two injections, usually for 4–8 weeks loading, then taper.
How long is a typical TB-500 protocol?
Most protocols use 2 to 5 mg weekly across four to six weeks.
How should TB-500 be reconstituted for use?
The vial is mixed with bacteriostatic water drawn slowly down the side, then swirled rather than shaken.
How often should TB-500 be injected each week?
A typical loading phase runs at 2–5 mg once a week for 4–6 weeks, then drops to a maintenance pin every 2–4 weeks.
