Typical timeline
General pattern for the Immunity category. Individual response varies.
- Week 1Subtle. Sleep may improve as inflammation drops.
- Weeks 2–4Fewer minor infections, better recovery from training or travel stress.
- Post-cycleBenefits carry for weeks. Bioregulator-style cycles (20–30 days on, then off) are typical.
The reconstitution math
- 1Reconstitute the 20 mg vial with 2 mL of bacteriostatic water. Tilt — don't shake.
- 2Concentration becomes 10,000 mcg/mL (10 mg/mL).
- 3For a 2 mg dose, draw 0.200 mL — that's 20 units on a 1 mL insulin syringe.
- 4One vial gives you approximately 10 doses.
Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
