No. TB-500 is not approved by the FDA, EMA or any regulator for human use. It is sold as a research chemical of unverified identity and purity, and it sits on the FDA's 503A Category 2 list, meaning it cannot legally be compounded. The World Anti-Doping Agency also bans thymosin-β4 and its derivatives, including TB-500, at all times under S2 (Growth Factors). OptiPin is a tracking tool and does not endorse obtaining or using it.

Does the tracker work offline and keep my data private?

Yes. OptiPin stores everything on-device and works offline. There is no account and no cloud sync requirement, so your log is not uploaded to a server.

TB-500 Tracker for iPhone

OptiPin is a private TB-500 tracker that turns a recovery-peptide protocol into a clean, reviewable record. Log each injection on a twice-weekly cadence, reconstitute vials with the built-in calculator, rotate injection sites, track recovery and side effects over your dose timeline, and note how you feel - with a reminder when the next dose is due and a warning before a vial runs out. Everything stays on your device; no account, no cloud upload.

Status - research compound (as of June 2026)

Unapproved, WADA-banned. TB-500 is a synthetic fragment of thymosin beta-4 sold as a "research chemical" - it is not approved by the FDA, EMA or any regulator, and sits on the FDA's 503A Category 2 list (cannot legally be compounded). WADA bans "thymosin-β4 and its derivatives, e.g. TB-500" at all times under S2 (Growth Factors), with real sanctions and a long horse-racing doping history. TB-500's own human evidence base is essentially empty. OptiPin is a tracking tool and does not endorse or facilitate obtaining it.

Why track TB-500 at all

TB-500 is a synthetic fragment of thymosin beta-4 studied for soft-tissue and tendon healing, and it ships as a lyophilized vial rather than a pre-filled pen. That means there are two things to keep straight that a notes app won't: the reconstitution math (vial size + bacteriostatic water → syringe units) and an honest record of whether it's actually doing anything. TB-500 has essentially no human trials of its own, so the only credible read on an unproven compound is your own carefully logged recovery against which doses, on which days.

OptiPin handles the vial side natively - pick the compound, reconstitute, and every injection is logged in real units against a timeline you can actually read, with the recovery outcome you care about charted alongside.

What the OptiPin TB-500 tracker does

Dose log + reminders

Record each injection on a twice-weekly cadence (e.g. Mon & Thu) and get reminded on the due day so a shot never slips.

Built-in reconstitution math

Pick TB-500 and OptiPin converts vial size + bacteriostatic water into exact syringe units - no hand math.

Injection-site rotation

Track which site you used last so you can rotate SubQ sites - abdomen, flank, thigh - consistently.

Side-effect logging

Note injection-site reactions, fatigue, head-rush and anything else, and see how it lines up with each dose.

Recovery notes over your timeline

Log the joint, tendon or soft-tissue outcome you care about and see it charted directly over your injections.

Vial runout warnings

Log the reconstituted vial and OptiPin estimates remaining doses and an empty date, warning before you run out.

CSV import & export

Bring an existing dose history in from a spreadsheet, or export your log to share with a clinician.

Running TB-500 in a stack? It's most often paired with BPC-157 in the community "Wolverine stack" for recovery - OptiPin tracks each compound separately on one shared timeline, alongside any peptide like GHK-Cu or your TRT. For the thymosin-β4 distinction, evidence and reconstitution math behind the molecule, see the TB-500 reference.

Free dose tools for TB-500

Calculators that pair with tracking - no app needed to use them:

Peptide blend calculator - splits a multi-peptide vial into per-peptide syringe units for the Wolverine (BPC-157 + TB-500) and GLOW stacks.
Reconstitution calculator - turns vial size + bacteriostatic water into exact syringe units (and works in reverse).
Half-life visualizer - see how any half-life and injection interval accumulate over time.
TB-500 reference - the thymosin-β4 distinction, what the evidence shows, status and the reconstitution math, with sources.

One app for everything you're on

The real advantage of OptiPin is that TB-500 doesn't live in isolation. If you're also running BPC-157, on TRT, or working a peptide stack, all of it sits in one place with a single timeline and one set of insights - instead of fragmented across a notes file and your memory. That's the difference between logging a compound and actually seeing your protocol.

Not medical advice, not a dose, not a sourcing guide. TB-500 is an unapproved research compound with minimal human safety data and is banned in tested sport. OptiPin records and reminds - it does not recommend a dose, a protocol, or whether to use TB-500, and does not endorse obtaining research-grade material. The reconstitution tools above are arithmetic for whatever a clinician specifies. Discuss any peptide with a qualified clinician.

FAQ

Is there an app to track TB-500?

Yes - OptiPin. You log each injection on a twice-weekly or weekly cadence, reconstitute vials with the built-in calculator, rotate sites, log recovery and side effects over your dose timeline, and get reminders plus runout warnings. It's on iPhone, stores data on-device and needs no account.

Is TB-500 approved?

No. TB-500 is not approved by the FDA, EMA or any regulator. It's sold as a "research chemical" of unverified purity and is on the FDA's 503A Category 2 list (cannot be compounded). It's also WADA-banned - "thymosin-β4 and its derivatives, e.g. TB-500" under S2 (Growth Factors). See the TB-500 reference.

Can OptiPin help reconstitute TB-500 vials?

Yes. TB-500 comes as a lyophilized vial; the built-in reconstitution calculator turns vial size and bacteriostatic-water volume into exact syringe units (the same tool is free on the web). It's arithmetic only, not a dose recommendation.

Can it track the Wolverine (BPC-157 + TB-500) stack?

Yes. OptiPin tracks each compound separately - its own schedule, dose log and vial inventory - on one shared timeline, and the free peptide blend calculator covers Wolverine and GLOW. This is community practice, not clinical guidance: there are no human trials of the combination and both peptides are unapproved and WADA-banned.

Does it work offline and keep my data private?

Yes. Everything is stored on-device and works offline. There's no account and no required cloud sync, so your log isn't uploaded to a server.

Educational only, not medical advice. TB-500 is an unapproved, investigational research compound with minimal human safety data and is banned in tested sport. OptiPin is a tracking tool and does not provide dosing or treatment advice, nor endorse obtaining research-grade material. Discuss any peptide with a qualified clinician.
