Ive got 1 gram of T3 sodium salt powder sitting around. Looking to dissolve it, was going to use ethanol but apparently thats not the answer. Maybe ill just have to sacrifice some for the sake of experimentation with a variety of different solvents and see what works.
Using 20L of ethanol is a no go for sure. Ive got propylene glycol, glycerin, DMSO, PEG400, trimethylene glycol, methanol, ethanol, and some other things in my lab. Wait, maybe ill research this through scientific channels...
T3 (sodium salt) is supplied as a crystalline solid. A stock solution may be made by dissolving the T3 (sodium salt) in the solvent of choice. T3 (sodium salt) is soluble in organic solvents such as DMSO and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of T3 (sodium salt) in these solvents is approximately 1 and 0.25 mg/ml, respectively.
T3 (sodium salt) is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, T3 (sodium salt) should first be dissolved in DMF and then diluted with the aqueous buffer of choice. T3 (sodium salt) has a solubility of approximately 0.5 mg/ml in a 1:1 solution of DMF

BS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day.

Thank you for your question.
We recommend dissolving in DMSO. At room temperature, it is soluble up to 100 mg/ml. In water and ethanol, its solubility is 1 mg/ml. It is also soluble in a 1:4 mixture of HCl:EtOH at 10 mg/ml.
Please contact Technical Service if you have further questions concerning this product.

Soluble in water (partly miscible), dilute alkalies, 1 M HCl:EtOH (1:4) (10 mg/mL), DMSO, 100 mM NaOH (10 mg/ml), 4 M NH4OH in methanol (5 mg/ml), 1 N HCl : Alcohol mixture (1 : 2),
50% Ammonium hydroxide (20 mg/ml - clear, brown solution), 1 N Sodium hydroxide, alcohol (slightly), and ethanol 96% v/v (slightly). Practically insoluble in most other organic solvents.

Sooooooo it looks like DMSO is the winner for T3 (sodium salt). Its important to note this is for sodium salt, if you had freebase it may not apply. Is DMSO safe to ingest orally i wonder? I know its great for transdermal. *googles*
Answer: yes it is safe for oral use. But how safe? According to wikipedia its safer than ethanol for the LD50: DMSO is a non-toxic solvent with a
median lethal dose higher than ethanol (DMSO: LD50 Oral-Rat-14,500 mg/kg,
[31] Ethanol: LD50 Oral-Rat-7,060 mg/kg
[32]).
Things to note: DMSO in your eye will blind you, so definitely wear eye protection although that should be a given for anything. Gloves too, obviously.
