Citicoline (CDP-Choline) vs Tesamorelin (Egrifta)
Both are used for focus & cognition. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Citicoline (CDP-Choline) | Tesamorelin (Egrifta) | |
|---|---|---|
| Human evidence | ★★★★☆ | ★★★★☆ |
| Legal status | OTC Supplement | FDA Approved |
| How it works | Choline + cytidine → precursor for acetylcholine synthesis and for phosphatidylcholine (neuronal membranes); also raises dopamine receptor density. Prescription (Somazina) for stroke in some countries. | Stabilised 44-amino-acid GHRH analog binding the pituitary GHRHR, driving pulsatile GH → hepatic IGF-1. FDA-approved to reduce visceral adipose tissue in HIV-associated lipodystrophy. |
| In plain English | Feeds your brain the raw materials to make its "memory and focus" chemical (acetylcholine) and to build cell membranes. Well-tolerated, decent evidence for attention. | A refined copy of the brain's "release growth hormone" signal. Uniquely proven to shrink deep belly fat, and the only GH-releasing peptide with an actual FDA approval. |
| Bottom line | One of the better-evidenced cholinergic nootropics. | The legitimate, approved member of this family. |
| Availability | Available over the counter | Available over the counter |
Which is better for focus & cognition?
Both carry a comparable human-evidence rating (★★★★☆). Choose on mechanism fit, side-effects, availability and cost rather than evidence strength alone — they work through different mechanisms.
