The immune peptide — chosen for post-illness recovery, heavy travel seasons and anyone whose stack was missing the immune-support piece.

Thymosin Alpha-1 (TA1) is a 28-amino-acid peptide naturally produced by the thymus, where it helps train and regulate T-cells. A synthetic version is an approved medicine in a number of countries (as Zadaxin) for hepatitis B and as a vaccine adjuvant, and it has been studied widely as an immune modulator — supporting, rather than over-stimulating, immune function.
In the wellness world it is used for immune resilience: after illness, before and during heavy travel, and in longevity stacks where immune function is a pillar. It is not FDA-approved and is offered here in a wellness context after clinician screening.
Guests typically come to Thymosin Alpha-1 seeking:
Sealed, COA-verified vial delivered in Tulum. You reconstitute and dose yourself. +$15 delivery, free over $250. A clinician still does a quick screen before we confirm.
Bac water, a month of syringes, reconstitution syringes, prep pads, your personalized dosing page with batch certificates, a taught first dose and WhatsApp support. Kit is +$85 once per order, however many vials. Delivery included.
10 mg + 2 mL bac water = 5 mg/mL, so 1.6 mg = 32 units.
1.6 mg subcutaneous twice a week is the most common wellness protocol. A 10 mg vial is about three weeks; many guests run 4–8 weeks.
General guidance, not a prescription — your clinician confirms your protocol at screening. Reconstituted vials keep ~4 weeks refrigerated.

Every vial ships with a Certificate of Analysis you can check against the lab’s own database — identity, content and purity by HPLC and mass spectrometry — and your dosing page carries the batch number that matches the label. Buy the vial alone if you know what you’re doing; add the kit if you want a clinician to teach the first dose. These are investigational peptides, not FDA-approved, offered in a wellness context after individual screening.
A peptide your thymus makes to regulate T-cell immunity. The synthetic version is an approved medicine in several countries (Zadaxin) and is studied as an immune modulator. Not FDA-approved; offered here in a wellness context after clinician screening.
Modulator is the better word: it is studied for helping immune responses become more effective and better regulated, not for over-driving them. That is why it is used for resilience rather than as a treatment for any specific illness — and we make no such claim.
10 mg reconstituted with 2 mL bac water gives 5 mg/mL, so 1.6 mg is 32 units, typically twice a week. A vial lasts about three weeks.
Yes. Vials-only is $95 with Tulum delivery ($15, free over $250). The Start & Continue kit adds bac water, syringes, a dosing page and a taught first dose for $85 per order.
