Dihexa — Complete Dosing Protocol & Guide

Dihexa is a cognitive peptide — the cognitive category covers memory, focus, neuroprotection, mental clarity. Angiotensin IV analog that is 10 million times more potent than BDNF at promoting synaptogenesis — enhances cognitive function, memory consolidation, and neural repair. In research settings it is administered oral at a frequency of 1-2x daily, with an elimination half-life of ~hours and a studied dose range of 5 mg–10 mg per administration (about 72 mcg/kg of body weight).

Angiotensin IV analog that is 10 million times more potent than BDNF at promoting synaptogenesis — enhances cognitive function, memory consolidation, and neural repair. That mechanism places it in the cognitive category. Pharmacokinetically, its elimination half-life of ~hours is what shapes the 1-2x daily dosing cadence used in research protocols, and the full effect builds across a 4-12 weeks cycle followed by 4 weeks off — which is why the dosing is cycled rather than continuous.

Dihexa is taken oral. The research-standard frequency is 1-2x daily, with a half-life of ~hours. Keep administrations evenly spaced across the dosing period so plasma levels stay steady. Always start at the low end of the dose range, use aseptic technique for injections, and follow the 4-12 weeks cycle followed by 4 weeks off. PeptideWise calculates the exact dose and schedule for your body weight and goal.

Research protocols use 5 mg–10 mg per administration, weight-based at roughly 72 mcg/kg of body weight, administered 1-2x daily. For an 80 kg (176 lb) adult that works out to about 2.9 mg for a beginner, 4.3 mg for an intermediate, and 5.8 mg for an advanced research protocol. Start at the bottom of the range and titrate up only while the response is tolerable — the personalized protocol engine on this site computes the exact figure for your weight.

The standard research cycle is 4-12 weeks, followed by 4 weeks off. Cycling matters because continuous exposure leads to receptor desensitization (tachyphylaxis) — the same dose produces less effect over time — and side effects fade during off periods. Don't extend the cycle past 4-12 weeks chasing diminishing returns.

Yes. Dihexa is commonly researched alongside NAD+, Epithalon (Epitalon). The best stacks pair peptides that act through different mechanisms toward the same goal — for example BPC-157 (angiogenesis) with TB-500 (cell migration). Introduce one peptide at a time, align cycle lengths, and cap stacks at 2–3 peptides so effects stay attributable. The protocol engine on this site only recommends stack combinations that pass safety screening for your conditions and medications.

Reported in research and trial settings: mild headache; vivid dreams; anxiety (at high doses). Most are dose-dependent and resolve when the dose is reduced or the cycle ends. If any severe reaction occurs (chest pain, severe abdominal pain, difficulty breathing, signs of an allergic response), stop immediately and seek medical evaluation.

Dihexa carries a good research safety profile at the doses described above, but safety is individual. It is contraindicated in research settings with: cancer, psychosis, bipolar, pregnant, breastfeeding. It is not medical advice to run any peptide without supervision — consult a qualified healthcare provider who knows your full history first, get baseline labs, and re-check during the cycle. 🧠 As a cognitive peptide, Dihexa is sold for research use only.

Dihexa is sold by research-chemical suppliers for laboratory research use only — it is not an approved dietary supplement or consumer product, and regulations vary by country and jurisdiction. Before considering any source: (1) consult a licensed healthcare provider about medically supervised options, (2) if purchasing for research, verify third-party certificates of analysis (COA) confirming purity and identity, and (3) be wary of prices that look too good to be true — they usually are. PeptideWise does not sell peptides; we provide dosing research and protocol tools.

Dihexa is taken orally, so no reconstitution is needed — it is dosed directly as a capsule or measured powder per the research protocol. Our general reconstitution guide (bacteriostatic water, concentration math, storage) applies to the injectable peptides in the database.
