Description
Tiros (T3) 50 mcg Pharmacom Labs — liothyronine (T3) from Pharmacom Labs at 50 mcg. Active thyroid hormone bypassing T4-to-T3 conversion. Thermogenic and fat-oxidation effects during cutting cycles. Always with anabolic base to protect muscle.
Key Benefits
- Synthetic thyroid hormone — overrides metabolic rate
- Pair with testosterone to prevent muscle catabolism
- Taper up from 25 mcg, taper down at cycle end
- Monitor TSH, free T3/T4 before and during
- Aggressive fat-burner — harsh on cardiovascular system
- Each unit dosed at 50 mcg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: start 25 mcg/day, titrate by 12.5 mcg every 5–7 days to 50–75 mcg/day. Taper down similarly at end — do not stop cold. Cycles 6–8 weeks.
How It Works
Liothyronine, synthetic triiodothyronine (T3). Exogenous T3 suppresses TSH and shuts down endogenous thyroid output — taper critical to avoid hypothyroid rebound. Aggressively raises metabolic rate; catabolic to muscle without anabolic support.
Pharmacokinetics
Plasma half-life approximately 1–2 days. Once-daily dosing. Steady-state in 7 days. Endogenous thyroid suppression develops within a week.
Potential Side Effects
Tachycardia, sweating, insomnia, irritability. Muscle catabolism without anabolic support. TSH crashes — TFTs before starting, during, and 4 weeks after. Cardiovascular stress significant.
Cycle & Stacking Guide
6–8 weeks within an aggressive cut, always with testosterone base (150–200 mg/week minimum) to prevent muscle loss. Stack with clenbuterol for synergy. Not a standalone fat-burner.
Manufacturer Notes
Pharmacom Labs operates from EU-registered facilities with in-house HPLC verification. Every batch ships with a unique code on the label — scannable at pharmacom-labs.com to confirm authenticity before the vial ever leaves the box.
Storage & Handling
Store in the original blister or bottle at 15–25 °C, away from direct sunlight, heat, and humidity. Oral preparations lose potency faster if exposed to moisture; keep the desiccant (if included) with the tablets. Keep out of reach of children. For research and educational purposes only.
