As a prohormone, the question of conversion rates is sure to come up and with good reason, as a PH’s conversion rate can make or break the product from an effectiveness standpoint. If only a small amount of the molecule is converted into the target hormone, any good intentions the manufacturer may have had are meaningless. A PH must have a high conversion rate and/or the ability to demonstrate adequate activity in its pre-conversion state, in order to be effective. While it is impossible to ascertain the exact conversion rate of the original compound based on its structure alone, it can provide a general idea of what to expect. With Trenabol, conversion is expected to be high. Initial user feedback appears to confirm this, lending further credibility to Trenabol’s claims of being a legitimate Trenbolone precursor.
