I understand you may be a little confused as to think that it has a faster half life than Enanthate because of so much misinformation out there on the internet and other forums. The fact of the matter is that hex has 8 carbon atoms which is one more than Enanthate and also has an extra oxygen atom attached to the chain as well making it even heavier. Tren hex, aka parabolan, has a half-life of approximately 14 days.

Lets clear up some Tren ester confusion. First comes Ace, then comes Enanthate, then comes Tren Hex. I've seen people get the last two confused and putting Tren Hex in between Ace and Enanthate. So Hex is a little longer acting than Enanthate.
The main difference between different esters is simply the number of carbon atoms in the ester. Propionate has three carbons, acetate has two, isobutyrate has four, enanthate has seven, cypionate has eight, and decanoate has ten. More unusual esters, such as cyclohexylmethylcarbonate (aka: Hexahydrobenzylcarbonate wich is used in Parabolan) has eight carbons and one more oxygen than the above esters making it the heaviest.

Trenbolone Acetate has a half-life of approximately 24-48 hours, Trenbolone Enanthate has a half-life of approximately 7-10 days, and Trenbolone Hexahydrobenzylcarbonate has a half-life of approximately 14 days.

TrenboloneHexahydrobenzylcarbonate has a half life of fourteen days.

 The Hexahydrobenzylcarbonate ester extends Trenbolone’s half-life to the extent of approximately 14 days rather than 3 days, which is the half-life of Trenbolone Acetate.

In comparison, Trenbolone Enanthate exhibits a half-life of approximately 7 – 10 days, and Trenbolone Hexahydrobenzylcarbonate expresses a half-life of approximately 14 days.

Ok so that Tren H I had no idea that I'm on Tri Tren right now and when I say the sides are bad like this is the worst Tren sides I have ever had. Tren A was my fav for years into I gave Tren E a go now I love it I just got hold of some high MG Tren E check my pics out. But this sounds like a good cycle to cut but to keep a lot of lean muscle if you ask me.

Yes it did
