Trenbolone Enanthate combines a very popular parent hormone (trenbolone) with a long acting ester (enanthate). This allows the advantage of once a week injections. It produces an impressive amount of new muscle fibre, with minimal water retention. This may be
done partly through an increase in IGF-1 within muscle tissue, and increased sensitivity of muscle satellite to IGF-1 and other growth factors and an increase in the amount of DNA per muscle cell.
