Semax
The "real-life Limitless" peptide — sharper focus, memory, and verbal fluency with zero stimulant jitter. It doesn't dump dopamine like Adderall; it rewires your brain by raising BDNF (your neuroplasticity "master switch").
📊 The Protocol
Vial10 mg
Mix with1 mL BAC water → makes 100 mcg = 1 unit
Dose5 units (500 mcg) — every day
WhenAM, fasted (empty stomach), under the skin
Cycle6 weeks ON → 6 weeks OFF, then repeat
🧮 Units made simple: your insulin syringe is marked 0–100. That whole line = 1 mL. Just draw to the 5 mark — that's your dose. No math, no guessing.
⏳ How long one bottle lasts
At 500 mcg 5u~20 days per bottle (a full cycle runs ~4.5 bottles)
One 10 mg vial = 100 units total. At 5 units a day that's 20 doses — so ~20 days per bottle, and a full cycle runs about 4.5 bottles.
💉 How to take it
Mix: add the 1 mL of BAC water slowly down the side. Swirl gently — never shake.
Store: in the fridge after mixing.
Inject: into belly fat, ~2 inches from your navel, in the AM fasted. Pinch, go straight in, push slow. Rotate the spot, fresh pin every time.
Skip the nasal spray — it's only ~10% absorbed.

🍽️ Your diet
Fix this firstSemax won't fix a broken diet. Dial food + hormones before expecting magic.
CutProcessed sugar and seed oils — they scramble focus.
AddSaturated fats (beef tallow, red meat, butter) — brain fuel for cognition.
💊 Take these alongside it
Focus stackL-tyrosine 3 g (dopamine precursor) + magnesium bisglycinate 500 mg + L-theanine.
EnergyNAD+ 50 mg — Semax gives the focus, NAD+ gives the energy to actually use it.
MitochondriaCoQ10 200 mg + PQQ 20 mg daily.
Pair withSelank at night — Semax = day/focus, Selank tapers any cortisol edge + calms.
⚠️ Watch for / red flags
Feeling wired or anxious? That's a cortisol edge some people get — add Selank to taper it, or drop the dose.
Headaches or flushing? Reduce the dose.
Don't run it forever. Prolonged non-stop use can blunt/desensitize how much you feel — that's why you cycle 6 on / 6 off.
"Marginal" is normal. Gains are a clean edge, not a superpower. If you feel nothing, your diet/hormones are the real bottleneck.
🚫 Who should NOT take it
Pregnant, breastfeeding, or trying to conceive
Under 18
You have a diagnosed anxiety or panic disorder — the cortisol edge can make it worse
Any active psychiatric condition — clear it with your doctor first
🔬 How it works
Semax is a synthetic ACTH(4-10) analog — a fragment of a natural brain hormone. It raises BDNF (brain-derived neurotrophic factor), the master switch for neuroplasticity, within the first ~3 hours — so your brain builds new connections. It's dopamine-sparing (protects your dopamine instead of dumping it like amphetamines), lowers brain oxidative stress, and keeps your antioxidants (glutathione + SOD) active. It's "building a better engine, not pouring more gas in."
💡 Pro Tips
It's the opposite of Adderall — no jittery, tweaked feel. You get clean focus and fewer "ums and uhs," not a buzz.
The standard stack is Semax + Selank (+ NAD+) — Semax focuses, Selank calms, NAD+ powers it.
Same-day you'll notice a focus lift, but the real payoff is cumulative — the rewiring stacks up over weeks.
Fix diet + hormones first. Semax on top of sugar + seed oils is a waste — cut those, add saturated fat, then run it.
