Its not the gains, its the recovery as it seems you already found out. It has a decanoate ester which is too long for cycling and PCT. After last pin you have to wait a long time for it to dissipate before you can start PCT, and a small amount still is getting released while on PCT, many times making the recovery worthless.
Test is test. No point in using blends. Just do enanthate, or prop if you want short ester.
