Product overview

Xeno Labs T4 100 mcg Levothyroxine Tablets

Xeno Labs T4 is levothyroxine sodium, the synthetic form of thyroxine, at 100 mcg per tablet in sealed packs of 50. It is run late in a cut, when a long deficit has pushed metabolic rate down and the scale has stalled. It is the storage hormone the body converts into T3, so it is usually paired with the faster-acting Xeno T3 and a thermogenic such as Xeno Clenbuterol. Buy Xeno T4 here.

How Levothyroxine Works

Levothyroxine replaces the thyroxine the thyroid gland normally makes, and the body converts it into the active hormone T3, which sets the pace of energy use in nearly every tissue. Because that conversion is gradual, T4 builds up slowly and clears slowly. That slow build is why the dose is started low and stepped up on a prescriber's schedule, and why the block is closed with a taper.

Dosage & Administration

The prescriber sets the amount and raises it gradually. Levothyroxine is taken once a day on an empty stomach, 30 to 60 minutes before breakfast, and community thyroid protocols pair 50 to 100 mcg of T4 with a smaller amount of T3 before tapering both. A missed dose is taken as soon as it is remembered, unless the next is nearly due; never take two doses at once. Higher amounts are not a shortcut: levothyroxine should not be used to treat obesity or cause weight loss, and large doses can cause serious or life-threatening problems, especially with stimulants such as amphetamines. Helios is the usual partner on the thermogenic side.

Quality & Authenticity

Each lot is made under GMP conditions and assayed by HPLC before release, with the result tied to the batch code on the strip. Keep the pack dry, at room temperature, out of direct light.

Prescription medicine: consult a healthcare professional before use.

Stacks

Thyroid Pair: Xeno T4 + Xeno T3

Xeno T4 50-100 mcg daily + Xeno T3 25-50 mcg daily, both tapered.

Outcome: a steadier curve, gentler steps between doses.

PCT: not required - neither compound suppresses natural testosterone.

Thermo Stack: Xeno T4 + Xeno Clen

Xeno T4 50-100 mcg daily + Xeno Clenbuterol 40-120 mcg daily, 2 on / 2 off.

Outcome: metabolic rate lifted while the beta-2 side burns more.

PCT: not required - neither compound suppresses natural testosterone.

Contest Cut: Xeno T4 + Winstrol

Xeno T4 50-100 mcg daily + Winstrol 50 mg daily for 6 weeks, the dry phase.

Outcome: definition sharpening, muscle kept under low calories.

PCT: required - Nolvadex 20 mg daily for 4 weeks, or Clomid as the alternative, because the oral steroid suppresses natural testosterone.

Consult a healthcare professional before any cycle. When a stack includes compounds that suppress natural testosterone, PCT is required. Dosages reflect community protocols.

FAQ

Before you ask

Questions, answered

It is levothyroxine sodium, the storage form of thyroid hormone (T4), at 100 mcg per tablet in sealed packs of 50. Cutting plans use it in the closing weeks, when a long deficit has pushed metabolic rate down and the scale has stalled, usually beside the faster-acting T3. Every lot is analysed per batch with the report on file.

Once a day on an empty stomach, 30 to 60 minutes before breakfast, with a full glass of water. The prescriber starts low and steps the amount up gradually, and community protocols run 50 to 100 mcg of T4 for four to six weeks before tapering down. A missed dose is taken as soon as it is remembered unless the next is nearly due, and two doses are never taken together.

No. T4 is levothyroxine, the storage hormone the thyroid releases in the largest amount, and the body converts it into T3, the active hormone that sets energy use. Because that conversion takes time, T4 builds and clears slowly and produces a steadier, gentler curve, while T3 acts and leaves quickly. The two are commonly run together, T4 as the base and T3 for the sharper edge.

At higher amounts it acts like too much thyroid hormone: chest pain, a rapid or irregular heartbeat, uncontrollable shaking, nervousness, anxiety, irritability, trouble sleeping, shortness of breath and heavy sweating. Other reported effects include changes in weight and appetite, headache, vomiting, diarrhea, fever, changes in the menstrual cycle, sensitivity to heat, hair loss, joint pain and leg cramps. Large doses can cause serious or life-threatening problems.

No for T4 itself. Thyroid hormone does not suppress natural testosterone, so a T4-only block needs no post-cycle therapy. When a steroid such as Winstrol is stacked with it, PCT is required - Nolvadex 20 mg daily for 4 weeks, with Clomid as the alternative, because the steroid suppresses natural testosterone.

Yes. Xeno Labs T4 100 mcg is stocked here in packs of 50 tablets with U.S. domestic and international delivery, and this page shows current availability and restocks. Every batch is GMP-manufactured and HPLC-verified with the Certificate of Analysis on file.
