TMA's positional isomer 2,4,5-trimethoxyamphetamine (2,4,5-TMA or TMA-2) is much more potent than TMA, with a dosage of 20 to 40 mg and a duration of 8 to 12 hours. [ 5 ] TMA is a low- potency serotonin 5-HT 2A receptor partial agonist , with an affinity (K i ) of >12,000 nM, an EC 50 Tooltip half-maximal effective concentration of 1,700 nM ...
TMA-2 is said to be active at doses of 20 to 40 mg and to have a duration of 8 to 12 hours. [1] It is much more potent than its positional isomer 3,4,5-trimethoxyamphetamine (3,4,5-TMA, TMA, or TMA-1), which is said to be active at doses of 100 to 250 mg and to have a duration of 6 to 8 hours.

TMA-2 may be: TMA-2 mine; Soyuz TMA-2, a Russian space exploration mission; 2,4,5-Trimethoxyamphetamine (TMA-2), a hallucinogenic drug;
A TMA-2. The TMA-2 is a rectangular plastic cased Yugoslavian minimum metal anti-tank blast mine.It is very similar in appearance and size to the PT-56, which it replaced.The mine consists of two sections, an upper ribbed pressure plate with two large circular fuze caps, and a lower base section containing the main charge and two primary fuze wells containing UANU-1 fuzes.
Soyuz TMA-2 was the second flight for the TMA modification of the Soyuz spacecraft, and the 6th Soyuz to fly to the ISS. The commander was Yuri Ivanovich Malenchenko (Russia), and the flight engineer was Edward Tsang Lu (USA). After docking with the ISS they exchanged with the resident crew on ISS and became the seventh station crew, called ...
Alexander Theodore "Sasha" Shulgin (June 17, 1925 – June 2, 2014) [1] was an American biochemist, broad researcher of synthetic psychoactive compounds, and author of works regarding these, who independently explored the organic chemistry and pharmacology of such agents—in his mid-life and later, many through preparation in his home laboratory, and testing on himself.

Dosage: 80–160 mg [2] Duration: 6–8 hours; Effects: Mydriasis, increase in heart rate, no psychedelic effects; History: 2,5-DMA was first synthesized in Tuckahoe, New York by Richard Baltzly and Johannes S. Buck in 1939. [3] It is a low-potency serotonin 5-HT 2A receptor partial agonist and has also been assessed at several other targets. [4]
WF 6 + Si 2 H 6 → W + SiF 3 H + 2 H 2, ∆H = –181 kcal The growth rate can vary from 4 to 7 Å/cycle depending on the deposition temperature (177 to 325 °C) and Si 2 H 6 reactant exposure (~10 4 to 10 6 L), factors that may influence Si 2 H 6 insertion into Si–H bonds [ 35 ] [ 36 ] and result in a silicon CVD contribution to the ...
