GB-115 vs Normoftal
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: Ranquilon, N-phenylacetyl-L-prolylglycine ethyl ester
GB-115 is a synthetic dipeptide anxiolytic developed in Russia, chemically the amide of N-phenylhexanoyl-glycyl-L-tryptophan and described as a retro-analogue of cholecystokinin-4. Rather than acting like a benzodiazepine, it blocks cholecystokinin receptors, a different anti-anxiety route. It has been studied in animals and in a small pilot human study, but it is not an approved or widely available medication.
Also: Eye Peptide Bioregulator, Retina Peptide
Normoftal is an obscure Russian eye supplement from the Khavinson 'peptide bioregulator' tradition, sold as short peptides meant to support the retina. Be clear-eyed about this one: it is marketed as a dietary supplement, not an approved drug, and the evidence behind it is thin and comes almost entirely from one research lineage. We keep the claims minimal on purpose.
Key Comparison Insights
- Both peptides belong to the Cognitive category, suggesting similar primary applications.

| Mechanism of Action | Cholecystokinin (CCK) is a peptide that acts as a neurotransmitter in the brain, and activating its CCK-2 (also called CCK-B) and CCK-1 receptors tends to trigger anxiety and panic-like states. GB-115 works as an antagonist at these cholecystokinin receptors, meaning it occupies the receptor and blocks CCK from setting off that anxiety signaling. In animal work it specifically prevented anxiety provoked by CCK-4, which shares a pharmacological target with GB-115. This CCK-blocking mechanism is the proposed explanation for its calming effect, and it is distinct from the GABA system that classic sedatives act on. | Khavinson's bioregulator theory holds that very short peptides (two to four amino acids) extracted from or modeled on a specific tissue can act as tissue-specific signals, switching gene expression and protein synthesis back toward normal in that organ. Normoftal is the eye/retina version, described as containing a synthesized peptide (marketed as 'AKS-G,' reportedly lysine and glutamic acid) intended to support retinal cells. The proposed mechanism is that the peptide corrects an age- or disease-related 'peptide deficiency' and restores normal cellular function in the retina. This is a hypothesis from one school of research, not a mechanism confirmed by independent molecular studies, and the specific composition claims come from vendors rather than peer-reviewed identification. |

| Research Summary | The research record is real but thin and almost entirely from a single Russian group. In rodent studies (rats, BALB/c and C57Bl/6 mice), GB-115 reduced anxiety induced by CCK-4 and by yohimbine, with effects that varied by mouse strain, and it stayed effective after long-term dosing without producing tolerance or a withdrawal syndrome when stopped. Preclinical safety work has also been published. The only human data comes from a small pilot clinical study of 25 patients with generalized anxiety disorder given 6 mg daily for 21 days, where anxiety scores on the Hamilton scale fell substantially and fatigue scores improved. Importantly, that study was a single-arm pilot with no placebo or control group, so it cannot prove the drug caused the improvement. There are no large randomized controlled trials, no Western regulatory approval, and the evidence base remains preliminary. | Normoftal is sold in Russia as a dietary supplement and is marketed for retinal degeneration, glaucoma, cataracts, diabetic retinopathy, and post-surgical recovery. Here is the part that matters most: it is not FDA-approved, and the evidence for Khavinson-style retinal bioregulators is heavily concentrated within Khavinson's own institute and clinical program, not replicated by independent international groups to modern standards. The related pharmaceutical Retinalamin is registered for clinical use in Russia, but that registration reflects the Russian system, not FDA or EMA review. There are essentially no rigorous, independent, placebo-controlled trials specific to Normoftal itself in mainstream literature. Treat the marketed eye-health benefits as unproven claims, and treat confidence in this compound as low. |
Frequently Asked Questions: GB-115 vs Normoftal
What is the difference between GB-115 and Normoftal?
GB-115 is a cognitive peptide that gb-115 is a synthetic dipeptide anxiolytic developed in russia, chemically the amide of n-phenylhexanoyl-glycyl-l-tryptophan and described as a retro-analogue of cholecystokinin-4. rather than acting like a benzodiazepine, it blocks cholecystokinin receptors, a different anti-anxiety route. it has been studied in animals and in a small pilot human study, but it is not an approved or widely available medication. Normoftal is a cognitive peptide that normoftal is an obscure russian eye supplement from the khavinson 'peptide bioregulator' tradition, sold as short peptides meant to support the retina. be clear-eyed about this one: it is marketed as a dietary supplement, not an approved drug, and the evidence behind it is thin and comes almost entirely from one research lineage. we keep the claims minimal on purpose. The main differences lie in their mechanisms of action and clinical applications.
Which is better, GB-115 or Normoftal?
Neither is universally "better" - the choice depends on your specific goals. GB-115 is typically used for cognitive purposes, while Normoftal is used for cognitive. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can GB-115 and Normoftal be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using GB-115 and Normoftal together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
