1-Testosterone (CAS No.: 65-06-5) is more of a mild hormone that will give you cleaner gains and dramatic strength increases. There are three prohormones to this compound:1-androstenedione, 1-androstenediol and 1-Androsterone aka 1-androstene-3b-ol-17-one.
1-Testosterone has a structure similar to testosterone but the double bond is in a different place. 1-Testosterone is a 1,2-double bond instead of a 4,5-double bond in its A ring. This slight modification means that the molecule is subject to different metabolism than standard testosterone. It cannot be converted to estrogen via aromatase nor can it be turned into DHT.
1-Testosterone would give you clean gains that are very dry and lean in nature. This means you won’t get a lot of bloat or estrogen activity with this prohormone. The lack of estrogen actually causes most people to stack this steroid with 4-andro or another “wet” compound. This helps potentiate the gains and increase the “comfort” of the cycle. 1-Testosterone will help give you clean gains that are very sustainable and help your strength go through the roof .
