But - that company (Valisure) is no longer doing consumer-submitted drug testing (they are focusing on their tested product pharmacy business). So you’d need to find a good and inexpensive lab to test for purity and any possible contaminants. Its a hassle for sure.
Another simpler (but not as good) approach is to just see how each of the drugs works in your body - take the medications, and then do a blood / sirolimus level test an hour after you’ve consumed the drug, and compare results. This addresses the bioavailability issue of each of the tablets - but doesn’t address any possible quality / contaminant risk issue.
I am glad you are considering this biological test.
It must have a good record as the PEARL clinical trial is using this in their evaluation as a baseline biological age… and evidence of change post dosing regimen.
Some heavy hitters in research supporting the trial including Dr. Mikhail Blogsklonny.
Understood. If someone wants to do the work to find a lab that will test samples, I’d be happy to chip in some funding.
I do plan to check my levels after I’ve been on the medicine for a while. As you pointed out, this will tell me something about the concentration & bioavailability of rapamycin, but nothing about possible contaminants.
Just curious… how many tablets were in the order that got seized vs. number in the other order that came through? Were they both the same sized order? Did only the smaller order get through?
Both orders were around 90mg of Sirolimus total. I should say Varun tried to send the item twice - both times it was seized by customs. My impression thus is that they may not have the most ‘effective’ method of sending Rapa without getting it seized.
My pharmacy Accredo sends the pills to me (3 months worth at a time - 90 total) – recently they changed to Dr. Reddy’s Laboratory which has been used in various clinical trials. It said it on the label. Same marking RD-54. So bascially same as Pfizer’s Rapamune 2 Mg Tabs
Used the Life Extension Testing (thank you for making that possible). I’m taking 4 mg - per Dr. Green - per week. Test was administered within 1 hour of ingesting Sirulimus. Took with a small swig of olive oil. Came back at 4.2 ng/mL. Did I test too soon? Does level seem a low?
LAB RESULTS
Tests Ordered
Sirolimus (Rapamune), Blood
Tests Result Flag Units Reference Interval Lab
Sirolimus (Rapamune), Blood 252-494-4042-0
Sirolimus, Blood 4.2 ng/mL 3.0-20.0 01
My AUC was .6 ng/mL on the day prior to my next dose.
The timing is tricky. Were you fasting when you took your sirolimus? Sirolimus usually peaks in two hours, but there are many variables. The therapeutic range for kidney transplants is >5 ng/mL. IMO, not advice. it looks like the level you got from 4mg is pretty good.
