Didn’t do much for me. I tried a personal experiment.
One benefit it is claimed to have is to increase telomere length. I’ve been measuring mine with the Trudiagnostic epigenetic DNA test, 6 tests in 5 years. The first 4 tests they were getting longer each test (I’ve posted my results before). I was taking NMN and NR, alternating those 2 depending on what else I was doing at the time. 7 months before the 5th test I stopped taking either of those and started Epitalon. My next test, telomers had gotten shorter. I stopped Epitalon and started back on NR, this time as a component of my MAX-5 Super Mix and the telomeres started recovering what had been lost.
Correlation is not causation, so it may have been something else that caused the dip.
Also I never “felt” much from Epitalon, but I don’t put a lot of stock in my feelings, I prefer measurements when I have the opportunity to measure.
I think one of my issues is that I “feel” pretty optimized and it would take an effect like I experienced when I did the first high dose cycle of SS 31 (10+10mg per day for 10 days) for me to say I felt that.
Recently I do notice when I take a break from the Ipa+CJC, more anthric pain after 2 weeks off. Reduction in pain after 1 week back on. Did see something interesting with the Renpho scale, a slight increase in VAT to 4lb (after months of stable 3lb indicated) that decreased after resumption of Ipa+CJC.
hGH is one of the better VAT (visceral adipose tissue) reducers.
I notice a difference when I take an extra dose of BPC+TB+GHK-cu when I’ve done something stupid in my physical activities. This on top of my daily 500mcg+500mcg+2.0mg shot in the morning.
And of course the GLP1 journey is easily measured.
As is my response to DSIP.
Did not notice much with extreme dosing with MOTS-c. 12mg per day for 30 days. 24x the Bro dose. That dose is based on a HED from the 30 day mouse trials that the hoopla is based on. Maybe an increase in muscle tone.
I carry NAD because people buy it.
Any time I get a request for that I send them a PDF the explains why NAD does not work, that it’s a scam and not to waste their money and just start taking NMN or NR orally. Most cancel their request, a few don’t care that it doesn’t work and place the order…
There are a few I refuse to carry and I’ll probably stop carrying NAD when I run out. I don’t do SLU-PP-332, it does not work in humans in it’s present format. the 915 version probably does as it was specifically designed to do so. And there are a few others.
I find that some effects are slow, because they are slow they become my new normal and I only notice there was an improvement when I stop.
Interestingly some of the things never come back because they are finally healed like my 2 ankles
they don’t “unheal” 
If asked, I offer people some of my personal experience (I’ve now used over 20 peptides) but I let them make the decision on what they want to try. I try not to bias new clients, unless I feel strongly against a peptide.
