Phenibut and Baclofen both come up in the same conversations; they overlap on GABA. Phenibut: Phenibut (beta-phenyl-GABA) is a Russian-developed anxiolytic and nootropic prized for delivering calm, sociable focus and easier sleep [1][3]. Baclofen: Baclofen is a centrally acting skeletal muscle relaxant and agonist of the GABA-B receptor, used chiefly to relieve the muscle spasticity caused by conditions such as multiple sclerosis and spinal cord injury.
Phenibut (beta-phenyl-GABA) is a Russian-developed anxiolytic and nootropic prized for delivering calm, sociable focus and easier sleep [1][3]. Because an added phenyl ring lets it cross the blood-brain barrier that ordinary GABA cannot, it acts chiefly as a GABA-B receptor agonist, the target behind its reputation for melting away tension and quieting a racing mind [1][3]. Introduced into Soviet clinical practice in the 1960s, it remains one of the most recognizable GABAergic nootropics on the market, used for anxiety, stress, and relaxation [1][3].
Baclofen is a centrally acting skeletal muscle relaxant and agonist of the GABA-B receptor, used chiefly to relieve the muscle spasticity caused by conditions such as multiple sclerosis and spinal cord injury. Chemically it is a derivative of the inhibitory neurotransmitter GABA, modified to cross into the brain and spinal cord. It can be taken by mouth or, for severe spasticity, delivered directly into the spinal fluid by an implanted pump, and it is also used off-label for alcohol use disorder.
both fingerprints on one instrument; where the marks line up the two compounds work the same lever, where a slot goes dark only one of them touches it. read straight from each entry's affinity table; nothing here is invented.

strengths are the entries' qualitative ratings (strong / moderate / weak); Ki and EC50 figures appear where an entry records them.
easiest to source: Phenibut is currently listed by more trusted vendors (4), so it's the simpler one to get hold of. for effects and safety, read each full entry; this is educational, not medical advice.
