So, around 7 months ago my 76 y.o. dad became obsessed with anti-aging stuff. He started lifting weights 3 times a week, running every morning, taking cold showers every morning and evening, stopped smoking and alcohol, intermittent fasting eating just once a day and taking TONs of supplements. He is retired, so, he has lots of free time at hand, most of which he spends "researching on the internet", or discussing anti-aging in his discord group. The rest he spends either gardening or in our garage repairing his cars.

He is following keto OMAD diet. Usually he eats in the evening big piece of meat/fish followed up with a large portion of very oily salad. The salads he is eating are like fat+vegetables at 50/50 ratio. It looks strange, but I'm fine with it. My real concern is his supplements. The supplements he is taking are

140mg CRL-40,941
250mg CDP-choline
250mg phosphatidylserine
1000mg histidine
25mg P-5-P intranasal
5000mg creatine
500mg ALCAR (sometimes more later)
250mg magnesium (1x more later)
600mg sodium butyrate
200mg alpha-lipoic acid (1x more later)
2000ug methyl B12 sublingual
50mg bromantane
0.5mg P21
12mg IDRA-21
5mg PRL-8-53 intranasal
20mg NSI-189 intranasal
40mg trans-ISRIB-A17 intranasal
15mg J-147
1mg semax
4mg brexpiprazole
10mg aripiprazole
20mg lutein xeanthine
0.15g RGPU-95

11mg Risperidone
120mg Vorinostat
40mg tranylcypromine buccal
8+4mg reboxetine
14mg JDTic
75mg bicalutamide
2.5mg selegiline buccal
12.5mg amisulpride
1.5mg naltrexone (ULDN)
10mg ramipril
20mg PPAP intranasal (+10mg later)
0.5g phenibut
10mg nitrendipine
200mg amantadine + 200mg later
0.2mg buprenorphine buccal + 0.2mg later

I might have missed some. The point is, he is super obsessed with this thing. Seven months ago he took Horvath's clock test at two different companies and both returned 71 years old. 1 month ago he took Horvath's clock test again and they returned 63 and 64.
