These are just the power multipliers I'm going to use for the story, however these might contradict with your head canon, so just know that I am changing how some things occur in the official dragon ball canon. I have no Beta readers and english is my fourth language so chapter updates might take a little while.
Power of Super Saiyan and Beyond Super Saiyan God are not here because I didn't want to integrate them, same with Legendary God Oozaru which are transformations that I don't want to do right now. Super Saiyan 4/God for Legendary Saiyans are not here due to how I changed their powers.
Base
False Super Saiyan (Base x 30) A regular saiyan is able to achieve this form by temporarily transforming into a great Oozaru and retaining their saiyan bodies, providing them with the strength of an Oozaru but with the agility and dexterity of a saiyan.
Super Saiyan (Base x 50 (Stackable with Kaioken x 2)) Once a legend, this transformation can only be access by having a great power level and feeling great concentrated anger. However the anger must be incredibly focused, so in combat it would be on an enemy and passively it would be on a small spot in your back. A great power level must be required to access the transformation and sustain it for a noticeable amount. Turns the user's hair up and golden.

Super Saiyan 3 (Base x 160,000)/(Base x 40,000 x 4) A transformation that is the last evolution of the regular Super Saiyan, increasing their golden hair down to their waist and increasing their power drastically, however stamina is greatly consumed making it impossible to be mastered.
Super Saiyan 4/ False Super Saiyan 2 (Base x 30,000)(Base x 1,000 x 30) A regular saiyan is able to achieve this form by temporarily transforming into a great Oozaru, then transforming into a Super Saiyan in that state then regaining conscious. This allows them to retain their saiyan bodies, providing them with the strength of an Super Saiyan Oozaru but with the agility and dexterity of a saiyan. This is weaker than a Super Saiyan 3 and it can only be retained in that state if there are blutz waves percent.
Mastered Super Saiyan 4 (Base x 600,000)(Base x 30,000 x 20) A mastered state of Super Saiyan 4 state where there is no longer a need of an active presence of blutz waves.
