Jarrow Formulas Rhodiola Rosea - Effects?

I am experiencing very mixed effects with this herb, most times it's a slight mood improvement or reduced fatigue but then again I was taking St. John's Worts at the same time. Really what I am looking for is a natural herbal supplement that will reduce fatigue but in more in-your-face sort of way, in that the effects are very noticeable. Edit: I've placed in an order for Super Rhodiola sometime this mid-week, so I am looking forward to seeing how that compares to Jarrow's version.
I also hardly experience anything when I take Sulbutiamine: I've tried 200mg to 1000mg (500mg b.i.d.). Did the researchers scan the brains of the subjects after they were given Sulbutiamine?
I'm also taking 6 x fish oil which has 330mg EPA & 220mg DHA per softgel. So ~3g of EPA and DHA. I take all 6 in the morning or sometimes, 3 in the morning and 3 in the evening. Is this a bit too much? I've not noticed any negative effects, actually I feel like my vision has improved somewhat.
Jarrow Formulas® Rhodiola extract is standardized to contain a minimum of 5% rosavins, the highest potency available.

Rosavins are used to provide proof that the source of Rhodiola is real, because it is unique to Rhodiola Rosea (however as of recent it seems like some companies have found ways to get Rosavins from other sources like soy). 5% is pretty high, especially if the Salidrosides are still at 1%. Naturally, the ratio is 3:1 Rosavins:Salidrosides. Anything else is probably spiked, or fake.
All this info can be found in The Rhodiola Revolution, by Dr. Patricia Gerbarg & Richard Brown, who specialize in Phytochemicals.

The most potent ingredient in Rhodiola, Tyrosol, is not even mentioned by anyone. Why standardize to an ingredient like Rosavin, when we are really concerned with the Salidroside and Tyrosol in the sample? Are people really concerned with the species used, or the active ingredients in the plant extract? I would think people care about effects first. If you have high levels of Salidroside and Tyrosol, then you will get the desired effects. Also, Rosavin can be synthesized. So its presence in a sample does not necessarily mean you have Rhodiola Rosea. All of our internal testing has shown Rosavin to not affect the stimulatory or antidepressant effects of Rhodiola. I find using it as a standard, or as a positive marketing statement, to be very silly.
