Test- Heptylate ?

I just started week 5 of test eth. 500 mgs. Deca 400 mgs. I am half way thru my first cycle and i am researching and planning my 2 nd( this is fun ) . Does anyone have any experience with test-heptylate (Calastreme) if so how does it compare with eth., sust, prop.

Thanks eveyone for sharing their knowledge.

cant compare it to much accept suspension, testex, and testiviron... Heptylate was unique in that I got good quality gains, loss body fat, and got stronger than anything i have ever taken... I feel heptylate is a must but i have found it hard to find
