Simon Smith I'm not yet into self-experimentation with Rapamycin, so I'm still far less competent than others. The evolution of the personal experiments here visible progresses quickly. Looking at other people practicing CR so far, at this intermediate stage of the evolution of Age Reversal (notably Bill Faloon and David Sinclair): if your body takes well Calorie Restriction, then you might not need Rapamycin. Steve Horvat's recent description of Biogenetic clocks at the EARD conference shows that Rapamycin stops the clock- and i think Drs. Green and Blagosklonny are trying to see if, used a bit differently, it could rejuvinate. It's very useful for people who would have trouble fasting (I had wheatgrass fasts in the past, but at 71 my muscle is reduced, my metabolism still requires food, so I was prescribed Rapamycin, Dasatinib and told to read dr. Vlassara's team's studies or her "The A.G.E. Less Diet" book (which is not a diet, just easy avoiding of Advanced Glycation Endproducts food - it does not seem to be given much importance, it's adaptable to all diets, I personally guess it can't hurt).
As for Senolytics, they've been found powerful; I'm not sure how the Life Extension one compares. I used to take it with many of the other LEF supplements you take - I took even more, but I have no idea how much they helped. I understand there are two types of senescent cells, one should be somewhat spared - I don't remember the source..
I find there are so many valuable people, including many doctors, on this forum, the Age Reversal Network has its own doctors, is conducting valuable experiments, one could possibly take part in them. On Rapamycin the PEARL study seems to be under way, (Lifespan.io). Other rejuvination factors have complexities for them to work (NAD is one of these, like Eric Verdin has just explained at EARD). There can be also interactions that can make one therapy contrast the others; I understand it comes down to careful timing, so I'd say that should not stop one from using more than one approach as long as one understands the timing - references on the forum and in specialised research studies (like the many found on Fight Aging). Some try to put the puzzle together, some self- experimenters try to get the maximum benefit from as many approaches as they can understand or be well advised on.
I must concentrate, like many I might have to check back here less often for a while. It's good to keep up with the latest info, then one has to bring it into one's use and balance life also. All the best! Flavio

Simon Smith Hi Simon from a fellow Torontonian. 56 yo male. Fired by family doctor, took on a functional medicine doctor (FMD), focused on prevention like most people here. Went strict keto (PLANT FATS BASED), one meal a day 5 years ago (for the powerful signalling metabolites in ketones, especially neurocognitive). I was intrigued by your comment re CR and muscle mass loss. I started daily resistance (30 mins free weights) followed by 5km treadmill (130 bpm) exercise regiment simultaneously (yes exercise is clearly my #1 health intervention). I promptly lost 50 lbs on the strict keto regiment over about 6-12 months. My muscle mass, however, has exploded on my regiment, and has nothing to do with diet or protein intake (I consume max 50 g net protein/day to stay keto)...but RESISTANCE training. Amino acids don't potentiate muscle hypertrophy...resistance exercise does. My weight has been very stable the last few years. I am in a tweaking mode...trading off eliminating the last vestiges of fat weight loss via very slight calorie reduction whilst increasing muscle mass with higher resistance exercise; increasing lean muscle build with fat loss to maintain weight. I take a large stack of supplements, several you referenced and more.

I did add Rapamycin to my stack in January of this year. Started at 4mg/week, now at 6mg/week, will keep increasing/testing biomarkers. Haven't had any side effects, glucose or lipid dysregulation. Have noticed IMPROVED liver and kidney biomarkers (eGFR is 100, like a 20 yr old), and reduced liver GGT, and very low uric acid.

Re Ferritin, I am of the "dumping as much iron as possible" camp. It's pro oxidative and PRO-AGING (several papers now making this association). I donate 450ml every 7 weeks (https://www.blood.ca/en), so I am completely turning over my whole body blood supply (including plasma) approx every 18 months, which is rejuvenating as it's own intervention. I had my Ferritin down to 12 last test (2 weeks after a donation). It normally ranges between 20-35 between donations. NO anemia like symptoms. Ferritin is NOT a good cellular biomarker for iron stores, . They tell you not to exercise for 24 hrs...I'm on the treadmill same day!

Simon Smith yes aware of the literature on metformin/exercise blunting. I don’t take metformin. With my ketogenic area under the curve, I am already blunting AMPK, and Rapamycin blows away metformin in terms of extending longevity in every animal model it’s been studied. Once I understood that I could continue my exercise regiment on Rapamycin, that’s when I dove in. Dump all the iron you can’t until you hit anemia. There’s a big pool there, depending on your unique N=1 profile. 

Simon Smith Do you know your genetic iron genes? For example, from a 23andme test?

I am homozygous H63D, means I tend to have higher Ferritin. In fact, my very first ferritin test several years ago, it came back at 350 (never donated blood, I was 51 yo).

Next lab bloodwork, do a full iron panel, and it's SATURATION that you want to look at, far more important than Ferritin.

Simon Smith that’s not the only hemo gene, there are several others, and depending on what test and genome array that was available, it might only catch the main ones.
