Make your arguments for Rapamycin dosed Once Weekly vs. Once Every Two Weeks

Here’s my Iron results for the two times I have taken a relatively small dose of Rapamycin

Units Iron micromolar/l Ferritin mcg/L

24-Aug-22 LM Iron 15 Ferr 205

31-Aug-22 LM Iron 20 Ferr 145

Rapamycin 2mg 4th Sept

07-Sep-22 LM Iron 10 Ferr 175

12-Sep-22 MPS Iron 18.1 Ferr 157.9

21-Sep-22 MPS Iron (?) Ferr 165.7

13-Dec-22 NWP Iron 21.2 Ferr 170.5

06-Jan-23 NWP Iron 8.3 Ferr 123.2

Rapamycin 2mg 10th Jan

11-Jan-23 LM Iron 17 Ferr 150

19-Jan-23 NWP Iron 14.8 Ferr 152.6

25-Jan-23 NWP Iron 18.4 Ferr 147.6

I think the reason my iron was low on 6th Jan was heavy drinking over Xmas. I am currently planning on taking Rapamycin 4mg some time next week. However, that plan may change.

Pretty sure I may be late to the party with this post. I apologize if it’s a duplicate.

Bryan Johnson has this posted on his Blueprint site:


"Every two weeks, I take 13 mg of gastro protected Rapamune. … To personalize dose and measure for safety and efficacy we’ve measured my Rapamycin blood levels 90 min, 4.1 days and 13 days post administration.

Blood Rapamycin levels:
90 min: 26.5 ng/mL
4.1 days: 2.5 ng/mL
13 days: not detected

Previously maintained a weekly Rapamycin dosing protocol of 6 mg. 24 hours post blood Rapamycin levels of the 6 mg dose were 3.2 ng/mL."


I’m still pondering either 6 mg weekly, or 12 mg every two weeks. Still a bit undecided, and from everything I’ve read, nobody really knows what is best so it might just be a case of pick one and run with it for a while and wait for hopefully more data to come in pointing in one direction or another.

Does he use enteric-coated capsules or something similar? If he does and the rapamycin dose is truly gastro-protected, then 13mg is a pretty high dose.

Go with 12mg every two weeks. They (attia podcast) almost but agreed in high doses at longer intervals.

Ya, that’s what I’m leaning towards…thanks.

BTW I’m doing 10MG with GFJ+EVOO. I’m thinking of upping it to 12-15mg with GFJ+EVOO and only do it once per month. I think I’ll give it a try that way see what happens.

BTW, if you have never taken RAPA before it is suggested you start low dose and up it. When I started I did 2MG first week then 3 next week and then 5 and after a while went to 10

I’m sure he’s just using Rapamune, and he’s using layman’s terms for the nanocrystal technology they use: Rapamycin and NanoCrystal Formulations

I believe BJ is testing a new weekly protocol. One week 12mg, second week 6mg or something similar. Check again his blueprint notes.

ls he taking injections or tablets?
“Rapamune® tablets, on the other hand, exhibited a 27% increase in the bioavailability of the drug”
Oh, well, I think I just stick to other forms of enhancement or take a few more pills.

Ya, I started with 3mg/week to get warmed up.

Oh right! Good find…in his July notes. He posts those using images so not searchable (I totally missed it!).


"Starting trialing new rapamycin protocol:
Week 1: 13 mg
Week 2: 6 mg
Week 3: 13 mg
Week 4: 6 mg

Safety + efficacy monitoring: body temp, sirolimus blood level, complete metabolic panel + routine biofluids, devices, imaging and fitness tests."

I attempted to move to a bigger dose on a 10 day dosing schedule but I didn’t like the kick in the butt from the bigger dose. I also didn’t like the P-I-T-A keeping track of a moving schedule (every dosing day was a different day of the week. I’m happy with a 7 day cycle now.

Perhaps I’m being too cautious but Blagosklony’s tweet & accompanying posted article on mtor surge is enough for me to put rapa on hold for a while until we get some clarity. Or maybe some very low daily or every other day low dose. I’m thinking until we get more info, taurine might be a safer play.

I’m up to 7 mg every 10 days. I might slowly boost to 9 mg every 10 days. So far the only side effect I’ve noticed is an itchy ass on day 2 (and I’m not talking butt cheeks). It’s happened two times in a row and only on day 2. I sometimes get the the same issue the day after I eat raw kale. Maybe someone needs to study the effects of kale on mTor! (I kid).
