How Do You Reconstitute Semax?
Use the volume the calculator returns above and add bacteriostatic water to your vial based on its size.
- If your vial is 2 mg, add 1 ml of bacteriostatic water.
- If your vial is 5 mg, add 2.5 ml of bacteriostatic water.
- If your vial is 10 mg, add 5 ml of bacteriostatic water.
- Once reconstituted, store the vial refrigerated and use within the active cycle window.
What Is the Concentration of Semax in Your Vial?
Concentration is held constant across every vial size so your unit count never changes.
- 2 mg vial reconstituted with 1 ml BAC water = 0.02 mg per unit.
- 5 mg vial reconstituted with 2.5 ml BAC water = 0.02 mg per unit.
- 10 mg vial reconstituted with 5 ml BAC water = 0.02 mg per unit.
- One unit on a 1 ml insulin syringe always equals 0.02 mg of Semax regardless of vial size.
How Many Units of Semax Do You Inject Per Day?
Draw to the unit line on your insulin syringe, not to a milligram figure.
- Daily range: 5 to 8 units per day on a 1 ml insulin syringe.
- At the low end (5 units): 0.10 mg of Semax per injection.
- At the high end (8 units): 0.16 mg of Semax per injection.
- Starting point: begin at 5 units and titrate up over the first 2 weeks if indicated.

When Do You Inject Semax?
Inject on the schedule the calculator returns above.
- Injection site: subcutaneous, abdomen.
- Timing: in the morning. Semax is the only peptide in the Perfect B protocol injected in the morning.
- Frequency: 5 days on, 2 days off.
- Site rotation: rotate the exact spot within the same abdominal area each session.
What Is the Cycle for Semax?
Semax is a cycled protocol, not a daily-for-life peptide.
- On phase: 2 months of active dosing.
- Off phase: 2 months pause.
- Repeat: patients typically run 2 to 3 full cycles per year.
- Why the off phase matters: continuous Semax dosing past 2 months flattens the cognitive and focus response the protocol targets. The pause is not optional.
Clinical tip: Semax is the only Perfect B peptide injected in the morning. If stacking with other peptides, keep schedules split.
Want the Same Protocol Built Around Your Goals?
Perfect B Aesthetic Medicine’s peptide protocol tool is built on real clinical data from 2,000+ patients treated in Florida.
Answer 6 questions and see what patients with similar goals are running: which peptides they use, typical dosing, injection schedule, reconstitution steps, cycle length, and when they pause.
Why Calculate Your Semax Dose at Perfect B Aesthetic Medicine and Not at Home
A calculator gives you the numbers. A clinic gives you the answer to whether those numbers are safe for you. The protocol behind the tool above runs the same way for every patient at Perfect B Aesthetic Medicine, and that is what separates a supervised cycle from a guess at the kitchen counter.
- Pharmacy-grade sourcing: your Semax is dispensed through a licensed compounding pharmacy. Identity, purity, and sterility are documented. Grey-market online vials carry none of those guarantees.
- Pre-protocol screening: labs, medical history, and contraindications are reviewed before a single vial is prescribed. Active cancer, pregnancy, bleeding disorders, and uncontrolled diabetes change the answer.
- Measured response: you do not guess if Semax is working. You measure response markers and any side effects across each cycle. The protocol can be adjusted when data justifies it.
- Reconstitution done right: a mistake at the BAC water step changes your dose by an order of magnitude. The clinic walks you through the first reconstitution so the math is correct from injection one.
- Real follow-up: the 2 months on, 2 months off cycle is monitored. If the protocol is not delivering, the clinic catches that early instead of three cycles later.
- Florida-based clinical context: Perfect B Aesthetic Medicine is the clinic with the most peptide patients seen in Florida. That volume means every parameter in the calculator has been pressure-tested across thousands of real cycles.
You can run the calculator at home. You should not run the protocol at home. The numbers are accurate, but they are only safe inside a clinical relationship that screens you, supervises you, and adjusts when your physiology calls for it.
Frequently Asked Questions
1. What is the correct Semax dose for you?
5 to 8 units per day on a 1 ml insulin syringe, equal to 0.10 to 0.16 mg per day. Start at 5 units. Inject in the morning.
2. How do you reconstitute your Semax vial?
Add 1 ml of bacteriostatic water for a 2 mg vial, 2.5 ml for a 5 mg vial, 5 ml for a 10 mg vial. Concentration stays at 0.02 mg per unit.
3. Where do you inject Semax?
Subcutaneous, in the abdomen, in the morning. Semax is the only Perfect B peptide injected in the morning. Rotate the exact spot within the same area each session.
4. Is this calculator a substitute for a consultation?
No. It surfaces the parameters the supervised protocol uses. The protocol itself starts with a medical evaluation, contraindication screening, and a written prescription from Perfect B Aesthetic Medicine.
