What is Blend 300 (TMT)?
Blend 300, often called TMT, combines three anabolic steroids in one oil at 100mg/ml each: trenbolone, masteron (drostanolone) and testosterone. It is a classic cut/recomposition stack that unites building, hardness and base testosterone in one shot.
Anabolic steroids, not peptides, ready to use.
How it works
The three components complement each other: testosterone as the base hormone, trenbolone as a very potent muscle/strength driver, masteron as a DHT derivative for hardness and a drier look (masteron does not aromatize and acts mildly anti-estrogenic). All bind the androgen receptor.
Use
Intramuscular (glute, thigh), ready to use.
- Inject with a clean IM needle, disinfect the injection site.
- Rotate injection sites.
- Subcutaneous: the TMT blend contains short esters and tren - more irritating subQ, so IM is preferred; subQ only very low volume and if well tolerated.

What the research shows
The individual compounds are described (trenbolone: Yarrow, 2010; masteron as a DHT derivative without aromatization). For the fixed triple combination there is no study, the benefit derives from the individual compounds. Performance doses are not study-proven.
Side effects
- Mainly from the tren part: sleep problems, night sweats, irritability, prolactin.
- Axis suppression from test and tren, lipid shift (masteron worsens it).
- Cardiovascular load, hair-loss risk (DHT part).
Practice
- Not a beginner stack, the tren part defines the profile.
- Watch bloodwork and prolactin, plan a post-cycle.
- Banned in official competition (WADA S1).
Storage
Store at room temperature, cool and protected from light, out of reach of children. Keep the original bottle closed and mind the expiry date.
