who's tried vit B5 for acne? Does is work? What dose do i need to take per day?

As above.. 

Not especially effective, depends on the severity of your acne.
If its the odd spot, then it may very well help.
10g a day is the suggestion mega-dose, tastes rather unpleasant though in powder form, and gives stomach upset.

If the acne is AAS induced then I doubt it will be especially effective.    
              

Tried it. Did nothing.

Seem to remember it wasn't that cheap either?

Its not cheap mate!

Ive just paid £8 for 50 / 500mg tabs 

Ive read u need to take up to 10 grams a day, ive taken 2 grams today. 

Loads of reviews on the net raving about it tho..??

Absolute scam if you ask me, did nothing for me anyway, I think its a complete myth created by the industry (IMO) a little bit like that acai berry scam
If you have steroid induced acne nothing is going to clear it except accutane or (possibly) time IMO

Vit B5 Did nothing for me either even at high doses.

Accutane.

If you run accutane wait until you finish your course. If you run the two at the same time, you will need more of the unpleasant med to shut down the sebaceous glands as the gear will be producing more oil from them in the first place.

Vit B5 does work in that it will dry your skin, but don't expect miracles.

try 100mg a day of zinc and then cut down to 50mg a day when things improve.

Best thing I ever did for acne/spots is to cut out most dairy and limit consumption to just milk proteins. 

B5 was mildly effective for me but only at mega-doses as stated....I found sea salt used as a skin scrub to be a millon times more effective and LOTS cheaper!
A couple of hits in the sunbed every week works very well also.
Where are the spots exactly??

Not sure how effective this would be, but if you do this make sure you have some copper or else you will get zinc poisoning.
