My experience:
I took C60oo every day at 3-16 mg since August, 2012 and only experienced benefits. The only side-effect is that alcohol has little effect on me. I don't get the fun high OR pain-relieving effect when I'm taking C60.
I've been off of it for over three weeks and used alcohol as a remedy for pain. I am resuming C60MCT at 2.4 mg/day for it's effects on energy production. The most notable things for the period that C60 has been "gone" from my body is that I can get drunk and feel less pain and I have less overall wildly-easy energy.
Two years age after being nearly defunct of weekly cardiovascular exercise, I decided to walk up a path to get to an area where one could hike barefoot. At 62 years of age, with a 20 pound bag of food, water and readable papers I hiked up 21 stories and decided to sit at a dry fount to eat, drink and read. After a while I thought, I'm 62, I've beaten myself up hiking this far and I would have to hike another 45 stories to get to the grassy hiking trails. I decided to descend. I drove the 90 minutes home, feeling quite beat-up. I took a hot shower for the negative ions and emerged from the shower feeling great.
C60 rocks!
Of course, we must ask if dogs respond to placebos. But obviously, dogs can show us a lot.
I can relate that some don't have the wonderful experience that I have with C60. (Turnbuckle, this means you!) But C60oo or C60MCT only causes efficient mitochondrial energy production. NO TOXICITY, "even when taken long-term," according to the interview of Dr. F. Moussa. My opinion, too, but based on published data.
Adding epitalon, especially with a thymic peptide, such as TB500, thymulin or other causes a tremendous improvement in "cleansing" pathways. Epitalon w/Thymulin caused the disappearance of skin lesions on my legs that were caused by exposure to toxins. These lesions were big red areas that persisted for many months.
Of all anti-ageing or AGE-REVERSAL molecules I rate C60 #1, with epitalon and thymic peptides both competing for number 2. This is what published data show about E and T. I am too busy to cite everything. But if you are skeptical I might answer your queries if you are polite, I find your question interesting, and have the time.
I am resuming daily use of C60, knowing that I will have to deal with chronic pain in other ways.
Peace!
