Semax is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Semax is administered via intranasal spray at 200-600 mcg daily 2-4 times daily. Subcutaneous injections into the abdominal fat or thigh are most common. Proper reconstitution with bacteriostatic water is required first.
How Do You Inject Semax?
Semax is administered via intranasal spray. For most researchers, subcutaneous injection is the standard approach — it's simple, relatively painless, and effective for Neuropeptide, nootropic, ACTH analog compounds.
This guide covers injection technique, site selection, needle choices, and common mistakes.
How Do You Prepare for a Semax Injection?
Step 1: Wash your hands thoroughly.
Step 2: Clean the top of the Semax vial and BAC water vial with alcohol swabs. If not yet reconstituted, see our Semax reconstitution guide.
Step 3: Draw your dose (200-600 mcg daily) into an insulin syringe. Use our calculator for exact units.
Step 4: Clean the injection site with an alcohol swab and let it dry.
What Is the Correct Injection Technique?
Subcutaneous (most common): Pinch a fold of skin — typically abdominal fat 2+ inches from the navel, or the thigh. Insert the needle at a 45-degree angle. Push the plunger slowly and steadily. Hold for 5 seconds, then withdraw.
Intramuscular (less common for Semax): Insert the needle at 90 degrees into the muscle (deltoid or vastus lateralis). This route provides faster absorption but isn't necessary for most peptide protocols.
Rotate injection sites to prevent lipodystrophy (fat tissue changes from repeated injections in the same spot).
What Size Needle Should You Use?
For subcutaneous Semax injections, 29-31 gauge insulin needles (½ inch or 8mm) are standard. These are thin enough to be nearly painless while long enough for proper subcutaneous delivery.
Use a fresh needle for every injection. Never reuse or share needles.

Mild redness, swelling, or itching at the injection site is normal and typically resolves within hours. Small bruises can occur, especially if you hit a capillary.
If you experience persistent pain, swelling, warmth, or redness lasting more than 24 hours, discontinue and consult a healthcare provider — these may indicate infection.
Bottom Line on Semax Injection
Semax is administered via intranasal spray at 200-600 mcg daily 2-4 times daily. Subcutaneous injection with a 29-31 gauge insulin needle into abdominal fat is the standard technique. Rotate sites and use a fresh needle every time.

Frequently Asked Questions
What is Semax?
Semax (Synthetic ACTH(4-10) analog heptapeptide) is a Neuropeptide, nootropic, ACTH analog. Developed by Russian scientists in the 1980s as a synthetic ACTH fragment analog for neuroprotection in stroke and cognitive decline. It is researched for BDNF elevation, neuroprotection, cognitive enhancement, stroke recovery, memory consolidation.
What is the recommended Semax dosage?
Common dosages: 200-600 mcg daily administered 2-4 times daily via intranasal spray. Cycle length: 5-14 days; repeated cycles with washout. Half-life: not established. Use our peptide calculator for exact reconstitution math.
What are the side effects of Semax?
Nasal irritation (dryness, burning). Nasal cavity discoloration in ~10% of users. Possible increased blood glucose in diabetics. Overall mild adverse effects.
Is Semax safe?
Semax has shown a preliminary safety profile in research. Not FDA-approved. Licensed pharmaceutical in Russia. Available as research chemical in US. All research should follow appropriate safety protocols.
