Does Trenbolone Enanthate take 3 weeks to kick in like Test Enanthate?

The ester is the half-life. A longer ester will stay in your system longer and build up, which is when most people notice the gear. I can feel it right away. Some people front load to feel it faster.

What does it mean when you say "Front Load" and what is "Half-Life"?
