Preparation & storage
- Preparation
- Mix a 5 mg vial with 2 mL bac water → 2,500 mcg/mL. A 1.6 mg dose = 0.64 mL = 64 units.

- Reconstitute a 5 mg vial with 2 mL BAC water → 2.5 mg/mL. A 1.6 mg dose = 0.64 mL = 64 units on a U-100 syringe.
Thymosin Alpha-1 interactions
with BPC-157
CompatibleThymosin Alpha-1 modulates immune function while BPC-157 promotes tissue repair — complementary mechanisms for recovery, especially useful post-illness or post-surgery.
Timing: Can be co-administered SubQ; different injection sites recommended
with TB-500
CompatibleThymosin Alpha-1 (immune modulation) and TB-500 (cellular repair/mobility) are a well-established recovery stack used in many longevity protocols. No known adverse interaction.
Timing: Inject both SubQ; independent timing
