Retatrutide, KPV, BPC-157, Thymosin Alpha-1, and Nicotine — targeting metabolic, inflammatory, and immune mechanisms simultaneously
Hashimoto's thyroiditis is an autoimmune disorder where the immune system attacks thyroid tissue, producing anti-thyroglobulin (anti-Tg) and anti-thyroid peroxidase (anti-TPO) antibodies. This leads to chronic thyroid inflammation, progressive follicular destruction, and eventual hypothyroidism — causing fatigue, weight gain, brain fog, metabolic dysregulation, and systemic inflammation. Standard treatment (levothyroxine) replaces missing thyroid hormone but does nothing to stop the autoimmune attack itself.
This protocol doesn't just replace missing thyroid hormone — it targets the autoimmune process driving the destruction. By combining metabolic optimization (Retatrutide), anti-inflammation (KPV/Nicotine), tissue repair (BPC-157), and immune rebalancing (Thymosin Alpha-1), it addresses the root causes rather than managing downstream symptoms.
Dose
1 mg per week
Frequency
Once weekly (Mondays)
Route
Subcutaneous injection
Mechanism: Triple agonist (GLP-1/GIP/Glucagon) that improves metabolic health and reduces inflammation in autoimmune models. Addresses the insulin resistance and metabolic dysregulation that accompany Hashimoto's.
Dose
400 mcg per day
Frequency
Once daily (morning)
Route
Subcutaneous injection
Mechanism: Alpha-MSH-derived tripeptide that suppresses NF-κB and downstream cytokines. Directly targets the inflammatory cascade driving thyroid tissue destruction.
Dose
500 mcg per day
Frequency
Once daily (morning)
Route
Subcutaneous injection
Mechanism: Promotes tissue repair and reduces autoimmunity in thyroid models. Supports regeneration of damaged thyroid follicles through angiogenesis and growth factor modulation.
Dose
500 mcg twice a week
Frequency
Mondays and Thursdays
Route
Subcutaneous injection
Mechanism: Modulates T-cell function and restores immune balance in autoimmune diseases. Shifts the immune response away from pathological self-attack toward normal tolerance.
