T4

T4 is Levothyroxine Sodium from Dragon Pharma, supplied as 100 tabs (50 mcg/tab). It is the gentler of the two thyroid products here, and its effect depends on the body's own conversion.    

It is in stock now and ships the same or next working day from our US domestic and international warehouses, in discreet packaging, and the batch can be verified against its laboratory report on request. The sections below cover what Levothyroxine Sodium is used for, how it is dosed, where it fits into a cycle and what to watch for.

T4 Product Details

T4 is supplied as 100 tabs (50mcg/tab). It is for oral use only. Its half-life is approximately 6 to 7 days, and it does not aromatise.

What Levothyroxine Sodium Is Used For

T4 delivers Levothyroxine Sodium as 100 tabs (50mcg/tab). Levothyroxine sodium is the synthetic form of T4, the storage form of thyroid hormone that the body converts into active T3. It is used clinically to treat hypothyroidism, and in bodybuilding as the gentler, slower thyroid option next to T3.

How T4 Fits Into Your Protocol

It is sometimes used alongside growth hormone, which reduces the conversion of T4 into T3, and it should be managed with bloodwork.

Side Effects & Cautions

T4 is supplied as 100 tabs (50mcg/tab), and the cautions below apply at that strength. Its effect depends on the body's own conversion to T3, so it is less predictable than T3, and it suppresses the thyroid's own output over time.

Batch-Tested & Verified Lab Results

Every batch of T4 that reaches PandaRoids is checked before it is listed. The pack you receive carries a batch number, and the corresponding laboratory report shows the measured content against the label claim. If you want the report for the batch you were sent, ask us and we will send it. That is the difference between listing that says lab tested and one that can show you the numbers.
