# Dihexa / Tesofensine Blend

> Dihexa / Tesofensine Blend pairs two structurally unrelated compounds studied for effects on brain function: Dihexa, a small molecule derived from angiotensin IV studied preclinically for synaptogenesis and memory support, and Tesofensine, a triple monoamine (serotonin, norepinephrine, dopamine) reuptake inhibitor originally investigated as a weight-management and Parkinson's disease drug candidate. The blend is marketed on the premise that Dihexa's proposed neuroregenerative activity may complement Tesofensine's stimulant-like effects on alertness, motivation, and mood. Evidence for either compound in humans is limited, and no study has evaluated this specific combination. Tesofensine carries a documented cardiovascular signal in clinical trials, including increases in heart rate, which is part of why it was not ultimately approved as a weight-loss therapy in the markets where it was studied.

- Also known as: Dihexa-Tesofensine Stack, DT Nootropic Blend
- Primary category: Cognitive Blends
- Effectiveness rank: #12 in Cognitive & Neuro; #2 in Cognitive Blends
- Evidence level: Emerging research
- Route: Subcutaneous (Tesofensine has been studied clinically as an oral compound, but this blend is formulated for subcutaneous co-administration with Dihexa.)
- Dose range: 125-500 mcg
- Dose tiers: low 125 mcg; moderate 250 mcg; high 500 mcg
- Half-life: Tesofensine has a long reported elimination half-life in humans, spanning several days due to an active metabolite, while Dihexa's half-life in humans has not been formally established, though its small, lipophilic structure suggests rapid distribution and clearance.
- Timing: Morning
- Cycle: 4 weeks on, 2-4 weeks off (Given tesofensine's cardiovascular signal and long half-life, conservative sources describe shorter on-periods with attention to heart rate and blood pressure. Combination-specific cycling has not been studied.)
- Storage: Store lyophilized powder refrigerated (2-8°C) away from light. After reconstitution, keep refrigerated and use within the supplier's stated window, typically 2-4 weeks.

## Mechanism of action

Dihexa is proposed to potentiate hepatocyte growth factor (HGF) activity at its c-Met receptor, a pathway linked in preclinical models to new synapse formation. Tesofensine inhibits presynaptic reuptake of serotonin, norepinephrine, and dopamine, increasing synaptic availability of all three, which is thought to underlie its studied effects on appetite suppression, energy, and mood. The blend combines a proposed neuroregenerative mechanism with a monoamine-based stimulant mechanism; these pathways have not been studied together, and possible interactions are not characterized.

## Reported benefits

- Tesofensine's monoamine reuptake inhibition is studied for increased alertness, motivation, and appetite suppression
- Dihexa is studied preclinically for synaptogenesis and memory-related support
- Delivered as a single combined product rather than sourcing two separate research compounds
- May appeal to users interested in both cognitive and stimulant-like effects

## Reported side effects

- Increased heart rate and blood pressure, a documented effect of tesofensine in clinical trials
- Insomnia or overstimulation
- Appetite suppression
- Injection site irritation
- Dihexa's human side-effect profile is not well characterized due to limited clinical data

## Common protocols

- Once-daily subcutaneous dosing, often in the morning given tesofensine's stimulant-like profile
- Short 4-week research cycles with cardiovascular self-monitoring
- Discussed in some sources alongside cognitive-training or exercise regimens

## Stacking notes

Combining this blend with other stimulants, monoamine-active compounds, or MAOIs is generally discouraged given tesofensine's cardiovascular profile. Anyone considering use alongside other medications should seek individualized medical guidance rather than relying on informal protocols.
