That’s what I’d do, and was doing for a while (plan to restart very soon). The Drexel study specifically was for anti-aging of the skin, and they used the equivalent of 1mg per 100ml of solution (although they used a cream or ointment, not solution). The concentration of the topical medicine for tuberous sclerosis is much stronger (100 times stronger, from your chart above). I might use 2 or 3 mg per 100mg of cream, but at least we aren’t talking orders of magnitude higher than the anti-aging skin study.

I don’t believe the Drexel study compared subjects taking rapamycin internally to the ones using it internally.

As I posted before, one of the first things I noticed after starting on rapamycin was a big improvement in my photo-damaged skin. The rapamycin taken internally stopped additional actinic keratoses from taking place and healed almost all of the ones I already had.
I have been treated for actinic keratosis for many decades because of my severe overexposure to the sun when I was young.

Because rapamycin works so well for my skin taken internally, I don’t really believe I am going to gain anything by using it externally. But I will try the 0.001% solution (1mg/100mL) a try.

My theory is that using rapamycin in creams etc, just wastes rapamycin because of the low absorption compared to the Transcutol and water solution. I like Transcutol because rapamycin dissolves in it easily and it penetrates deeply into the skin, but not too deeply.

The Drexel study compared topical rapa to topical placebo. I don’t know of any studies looking at oral rapa and skin aging/actinic damage/actinic keratoses.

When I made my cream a couple of years ago, i dissolved the rapa into transcutol and then mixed it into CeraVe lotion instead of water, which likely further enhances absorption into the skin.

Hello Rapa Admin, do you have any suggestions for ordering rapamycin powder besides LC labs? I’ve tried ordering from them without success because I don’t work in a laboratory. However, I am a practicing physician, but so far that hasn’t worked. I would really prefer to source a powder over pills for working with topical formulations if anyone has any suggestions. Thank you.

Can’t you just call in a prescription (for yourself) for sirolimus capsules to your local compounding pharmacy? if they don’t have a source for rapamycin powder, you might have to settle for ordering it from overseas.

#403

Yes - I’ve also ordered from the company mentioned at the top of the following thread (see link below), no issues. Fine for topical creams and toothpaste concoctions (from my experience): Here: Sirolimus Powder - 3rd party analysis

Soooo… any updates on how your homemade Rapa cream worked on your skin? Any pictures? It is a little intimidating for me to try and make this on my own but I sure have a lot of sun damaged/ precancerous skin from years on a sailboat.

Where can you buy rapamycin powder?

#407

People have mentioned these two sources: (I wouldn’t trust China suppliers for oral use, but for skin use its probably ok).

I recently read a couple of papers where researchers tested topical rapamycin and metformin on mice. They found that the treated mice regrew hair faster than the controls.
Impressed by these rodents, I decided to try myself. So I made up 2 solutions; a solution of 160mM metformin in water and a solution of 100nM rapamycin in ethanol.
I decided to use the metformin on my left forearm/hand and the rapa on my left leg below the knee. Right arm and leg are “pseudo-controls”. 1mL/day.
My skin has lots of sun damage due to a misspent youth on the beach with no sunscreen.
I’ll be shouting from the rooftops if there is any improvement!

Hi, Saw your post about the powdered Sirolimus from a compounding pharmacy.
Would you please be able to share their information?

Thanks
Cathy

It wasn’t my post. I don’t use or buy powdered rapamycin.

#411

I’m new here, so I’m sorry if this is annoying but I was wondering if there’s any kind of wiki or summary of the methods to make the cream and the pros and cons. This thread is… extensive! Hard to dig through.

Dear experts,

I am planning to make a skin cream based on products I have available.

Would anyone be so kind to comment on my suggestion below?
Should I add or change anything, in particular the dosing?

Suggestion for Skin Cream and Scalp Serum

I am based in Norway, and Propylene Glycol was easiest to get ahold of.

Thanks for any advice on both the skin cream and the scalp serum.

The Astaxanthin powder is probably unworkable… its a very powerful red dye and would stain your skin red. So I’d skip that (while I do think it might be helpful from a biological standpoint).

According to the NIH: "Conclusion: Although topical minoxidil has a better overall therapeutic effect than 1 mg oral minoxidil, the difference between the two groups was not significant. Therefore, 1 mg oral minoxidil may be as effective and safe as standard topical minoxidil in female and male pattern hair loss.Nov 29, 2023.
My concern with the oral minoxidil/spironolactone is that spironolactone decreases testosterone. Not worth it, IMO, if oral is not significantly better than topical.
