Was the study done with subjects taking Resveratrol shortly after or around exercise? This could be a major factor for this kind of results, similar than with Vitamin E and C. Resveratrol also downregulates mTOR pathway, so in my opinion taking it after training would be a bad idea, though I don't know how long does this mTOR inhibiton lasts. Amino acid Leucine activates the mTOR pathway signaling the body to favour muscle protein synthesis which in turn slows down or prevents muscle protein breakdown. So theoretically, the mTOR inhibition of Resveratrol may also inhibit muscle protein synthesis.

I think considering the dosage limitations of the study mentioned above, this one seems more in line with reality.

Chem Biol Interact. 2015 Feb 5;227:89-95. doi: 10.1016/j.cbi.2014.12.033. Epub 2015 Jan 5.
Effects of chronic resveratrol supplementation in military firefighters undergo a physical fitness test--a placebo-controlled, double blind study.
Macedo RC1, Vieira A1, Marin DP2, Otton R3.

PURPOSE:
The purpose of this study was to determine the plasma metabolic response and certain indicators of oxidative stress (antioxidant system and oxidative stress biomarkers) in plasma and erythrocytes of Brazilian military firefighters supplemented or not with resveratrol (RES) for 90 days (100 mg/day). The analyses were performed before and after a typical physical fitness test (FT) used to induce oxidative stress.
METHODS/RESULTS:
In this placebo-controlled double-blinded study, we observed that RES supplementation did not present hepatic consequences compared with the placebo group following analysis of AST, ALT and GGT plasma activities. Plasma glucose and triglycerides levels were increased after the FT in firefighters supplemented with RES but were not elevated at baseline. Neither total nor cholesterol fractions were modified by RES supplementation. CK levels were increased after the firefighters performed the FT; however, no differences were determined between the placebo and RES groups. Ferric-reducing ability of plasma as well as uric acid was increased after the FT, but was not modified by RES supplementation. Plasma oxidative stress biomarkers, such as thiol content, 8-isoprostane and 8OHdG, showed no modifications, while IL-6 and TNF-α were decreased in the RES group after the FT. Among antioxidant enzyme activities determined in erythrocytes from the firefighters, only GPx activity was reduced by RES supplementation both before and after the FT.
CONCLUSION:
In summary, the most pronounced effect of RES supplementation is its anti-inflammatory effect, which reduced IL-6 and TNF-α level. The FT applied to Brazilian military firefighters was not sufficient to challenge the antioxidant defense systems, and, therefore, 100mg of RES for three months did not induce significant effects.

Not sure If I got bad batches of Good Brand Name Resveratrol but it made my joints ache and overall a feeling of lethargy. I substituted high quality Grape Seed Extract and never looked back.

Too much res will chelate too much copper (safer levels range in the 100 to 200 mg range)

High copper has been on my suspect list for sometime now...

I believe I was taking the dose recommended here if not pretty close to it. How can I normalize it CS?

if a moderate level of resveratrol was having that effect, it could be that you are low copper rather than high.
