BHG Labs sells it as a capsule research compound with a third-party COA on every lot; that certificate tells you what is in the capsule, not whether it is safe in a person. this bench is not a treatment for anhedonia, depression, or stimulant withdrawal. if you are coming off a prescription, that conversation belongs with the prescriber. no dosing lives on this page. ## The bench: 2 compounds roles and evidence, not amounts. this page does not publish doses or schedules for research compounds. 1 9-Me-BC [read the guide](/compound/9-mbc) the beta-carboline. in cell and rodent work it raises tyrosine hydroxylase, the enzyme that sets the pace of dopamine synthesis, and it inhibits MAO-A at about 1 micromolar. evidence: rodent and cell data only. human safety data: none. watch for: it inhibits MAO-A, so the serotonergic and stimulant conflicts below are the hard rule. beta-carbolines are photosensitising and DNA-damaging under UV in vitro. a second methylation gives 2,9-dimethyl-beta-carbolinium, a cation in the same family as MPP+, the metabolite that makes MPTP a Parkinson's model. 2 L-Tyrosine [read the guide](/compound/l-tyrosine) the precursor. it gives the synthesis pathway substrate, which only matters if the pathway is the bottleneck. evidence: decent human data for performance under acute stress and sleep loss. weak for mood in rested people. watch for: competes with other amino acids for uptake. the blood-pressure concern comes from the MAOI and thyroid interactions, not from tyrosine on its own. thyroid conditions and MAOIs are reasons to skip it. Form capsules, as sold Human data none for 9-Me-BC; decent for tyrosine under stress BHG Labs carries 1 of 2 Level advanced ### Why these together on paper the logic is clean: 9-Me-BC pushes the enzyme that makes dopamine, tyrosine feeds that enzyme. the pair has never been tested together in animals or people. ### Overlap both act on the same pathway from different ends. what that adds up to in a person is unknown, and caffeine is a third input on the same axis. ### Conflicts 9-Me-BC with anything serotonergic (SSRIs, SNRIs, tramadol, DXM, St John's wort) is an MAO-A interaction and the one hard no on this page. 9-Me-BC with stimulants: no. UV exposure: the photosensitivity work is in vitro, and nobody has tested it in a person. tyrosine with levodopa or thyroid medication: talk to the prescriber. ### What the evidence actually is rodent neurorescue papers, cell culture, and forum reports for 9-Me-BC. no human trial has ever been run. the benefit chips you see elsewhere ('restores dopamine drive') describe rat data. tyrosine has human trials, mostly in sleep-deprived or cold-stressed subjects, and the effect fades in rested people. ### What people report user reports describe a lift in drive after one to two weeks and, for some, irritability. no trial has measured either. ### Who It's For experienced researchers with a log and no serotonergic medication. not for anyone treating a diagnosed condition. ### What to Track motivation on a fixed scale, sleep, blood pressure, skin reaction to sun, mood swings ## Sourced at BHG Labs Ownership disclosure: BHG Labs and BodyHackGuide are commonly owned.
