Quick Facts

What Is It?

Semax is a nootropic peptide derived from ACTH that supports focus, mood, memory and cognitive performance without being a stimulant. The way I'd describe the feeling: calm, clear, dialled-in focus — not jittery energy.

Who May Benefit?

People tend to reach for Semax for:

• Mental fog or trouble concentrating
• Work that demands sustained focus
• Low motivation
• Mental fatigue that lingers
• Stress resilience
• Brain health and neuroprotection

Benefits

• Increased focus and mental clarity
• Smoother mood
• Improved productivity without a crash
• Faster recovery from mental fatigue
• Stress resilience
• Neuroprotective support

How It Works

Semax works on the brain's own signalling rather than on your adrenaline system — which is exactly why it doesn't feel like caffeine. There's no rev-up and no corresponding crash. You mostly notice it as the absence of friction: you sit down to do the thing and you just do the thing.

What to Expect

Onset is quick — 30 to 60 minutes. You'll notice increased focus, a smoother mood, and productivity without the drop-off that comes with stimulants.

Cycle: 5 days on / 2 days off, or 2–4 weeks on then a break.

💛 T's Tip

Semax is my focus peptide and Selank is my calm one — and if you're wondering which you need, ask yourself whether your problem is can't concentrate or can't settle, love. This one is for can't concentrate. Take it in the morning; if you dose it late in the day you may find yourself still wide awake and organising cupboards at eleven at night. Start at 5 units and stay there a few days — going too high is the one way to make this one unpleasant, and it shows up as a headache or feeling overstimulated. Five days on, two days off keeps it working well. 💛 — T

Mixing

Add 2 mL BAC water to the 10 mg vial. Slowly down the inside wall, swirl gently until clear — never shake — and refrigerate.

At this mix, the concentration is 5 mg/mL, so 1 unit = 50 mcg (0.05 mg).

Dosing (not medical advice)

Standard range: 5–10 units per dose, 1–2× daily.

Timing: morning or early afternoon. Avoid dosing late in the day.

Cycle: 5 days on / 2 days off, or 2–4 weeks on then a break.

How Long Will One Vial Last?

One 10 mg vial (200 total units):

Side Effects

• Mild headache
• Overstimulation if the dose is too high

Both usually resolve by coming back down on the dose.

Storage

Refrigerate the reconstituted vial (36–46°F / 2–8°C). Don't shake it. Swab the stopper each time and use a fresh sterile syringe.

Helpful Tips

• Inject sub-Q in the belly or thigh
• Start low — 5 units. This one doesn't get better by being bigger
• Morning and early afternoon only
• Stay consistent; it's a simple and effective peptide when you don't over-tinker
• Rotate injection sites

FAQ

Can I combine this with my other peptides? Using more than one peptide is common and perfectly fine — but different peptides should not be combined in the same syringe. A few technically can be mixed, but they don't always play well together, and in some cases they can work against each other, so you lose the benefit of both. It isn't worth the guesswork. Keep each peptide in its own syringe — you can still take them in the same sitting, one right after another. When in doubt, keep them separate.

Semax or Selank — which do I want? Semax is focus and drive. Selank is calm and balance. If the problem is concentration, Semax. If it's anxiety, Selank. Plenty of people use both.

Can I take them together? Yes, and it's a popular combination — Semax for clarity, Selank to take the edge off. In separate syringes. A common pattern is Semax 5–10 units plus Selank 5 units in the morning, then optionally Semax 5 units and Selank 5–10 units in the afternoon.

Will it keep me awake? It can if you take it late. Keep it to morning and early afternoon.

I got a headache. That's usually the dose being too high. Come down to 5 units.

What does it stack well with? Pairs naturally with Selank and NAD+ — in separate syringes.

A Little Reminder

This isn't about perfection, it's about consistency. A clear head is a real thing to want, and wanting it doesn't mean anything is wrong with you. You're not lazy and you're not broken. I'm really glad you're here. 💛
