Research chemical vendors can't legally label products with the real name, so Semax often appears under coded SKUs. If you're shopping and see any of these, it's the same compound:

What to expect

Typical timeline

General pattern for the Neuro Cognition category. Individual response varies.

  1. Day 1–3
    Effect can be felt within hours: calmer focus (Selank), sharper attention (Semax), or deeper sleep (DSIP).
  2. Weeks 1–4
    Consistent daily benefits. Mood and cognitive stamina improve without stimulant crash.
  3. Post-cycle
    Take a break to avoid tolerance. Most users cycle 8 on / 8 off.

The reconstitution math

  1. 1Reconstitute the 10 mg vial with 2 mL of bacteriostatic water. Tilt — don't shake.
  2. 2Concentration becomes 5,000 mcg/mL (5 mg/mL).
  3. 3For a 500 mcg dose, draw 0.100 mL — that's 10 units on a 1 mL insulin syringe.
  4. 4One vial gives you approximately 20 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.
