9 vials of blood tested. Here’s the results.

Don’t panic. Go see a nephrologist, they’ll run some more tests on you. Cystatin C and a uACR test besides others. If you do have kidney issues, there are treatments you can take to slow the decline like SGLT2 inhibitors. The problem with the kidneys is that they don’t hurt when their function declines. But as a person who’s mother is on dialysis, please at least hear them out and go see a specialist. Good luck

I’d be damned if I would waste my time going to a specialist when for $40 I could test:

Creatinine

Cystatin C

eGFR (Creatinine)

eGFR (Creatinine + Cystatin C)

Urine Creatinine

Urine Total Protein

Urine Protein/Creatinine Ratio (uPCR)

Urine Albumin

Urine Albumin/Creatinine Ratio (uACR)

Here's my creatinine levels by date, you can see when I started taking creatine, and when I stopped.

And my cystatin C:

My default/baseline labs I get ran almost any time I have blood drawn are:

CBC with Differential

Comprehensive Metabolic Panel (CMP)

Hemoglobin A1c

Lipid Panel

Apolipoprotein B (ApoB)

Insulin

C-Peptide

hs-CRP (High-Sensitivity C-Reactive Protein)

IGF-1 with Z-Score

Gamma-Glutamyl Transferase (GGT)

If it's time to check my TRT labs, the default list for that is the baseline plus:

Testosterone, Total (LC/MS)

Testosterone, Free

Sex Hormone-Binding Globulin (SHBG)

Estradiol, Sensitive

Dihydrotestosterone (DHT)

PSA (Total ± % Free)

As an adjunct to my testing in a couple weeks (Baseline + TRT), I'm also running these for a periodic update, or for specific reasons (like ferritin and iron because I donated last month to lower my hematocrit).

Ferritin

Iron and TIBC

Free T3 (Triiodothyronine)

Uric Acid

Vitamin B12 and Folate

Magnesium, RBC

Cystatin C with eGFR

Homocysteine

Lipoprotein(a) [Lp(a)]

TSH + Free T4

Complete Urinalysis

Vitamin D, 25-Hydroxy

Urine Albumin/Creatinine Ratio (uACR)

Thyroid Antibodies

That’s fantastic.

I’ve been on GLPs and four other Pepitides since April. I’ve decided to get a very deep comprehensive blood panels every four months while on the peps. I’ve always done a fairly comprehensive annual blood test and have always had great markers. This blood test I literally had every test you could want to see regarding Pepitide use and total health. I even performed an auto immune disease test which came back negative. I had only four areas out of wack. Two were zero issue but a kidney and creatine panel came back a tad more concerning. My doctor called me and asked if I was on creatine and I said yes. He said to stop immediately that the creatine was damaging my kidneys. I stopped immediately and was even going to consult a nephrologist. Well last night I was doing my walk and listening to the podcast I added below. Got to about 7:30 into the podcast. He talks about the myths of creatine and listen to myth one. Oh my fucking god. Is there any doctor on this planet that knows what the fuck they are doing? It’s getting old. I’ve included a photo of blood panel being discussed here.

You’ve figured this out already but the normal eGFR on the CMP is useless if you’re running creatine and working out a lot. Both are serious confounders.

Go get Cystatin C drawn and calculate your eGFR off that. Not the combined creatinine/cystatin c eGFR, just the cystatin c one. That’ll be much more accurate.

On a recent draw I had a creatinine level of 1.3 and a cystatin c of 0.68. That corresponds to a creatinine estimated eGFR of 73 (not great) and a cystatin c estimated eGFR of 124 (that’s reta baby). Only the second one is close to accurate.

I'm no doctor, and certainly no expert in anything peptide or medical related, but I did just run labs last week on everything you did (plus a bit more), and my creatine was fine. I DO supplement with 10g of creatine a day, in a divided 5g dose. I do take KLOW and RETA. Just throwing that out there. I've been taking the pep's for about 6 weeks, but I've been taking the creatine for years. My creatine on previous labs was also in the normal range. I'm not sure if that helps you at all, but thought I'd share my own personal experience.

Same here. I've been taking 5-10g of creatine a day for almost 13 years and just had my annual blood work done last month. Results where the same as ever for creatine levels - totally in the normal range.

It might be just how our bodies metabolize or process the creatine differently, but there's obviously enough folks that take it daily for years without any issues.

It's unfortunate some folks do have issues with taking it, but it would be presumptuous to claim it's bunk as a supplement because of that.

Do you walk 5 miles a day and lift weights 5 times a week? And lifting the max weight your body can stand? Look at what creatine looks like with active high to moderate exercise. It’s fantastic. I’ve been doing creatine and high exercise since 2016. Agree fully. Everyone reacts differently like you said. I have zero worries about my heath.

Agree 100%! I belong to lots of FB groups for muscle building, etc. and there are lot of people who say creatine is a waste of money, that it gives them nothing but the runs, and/or they feel no difference. As you say, perhaps for them it is a waste. For me, I don't notice any bloat or other side effects, it lets me push harder in the gym (I've tested this many times), and at the 10g dose, I stay sharper/have less brain fog. Unless for some medical reason I would be forced to stop it, I'll take creatine for the rest of my life.

Spot on! I recently had very similar numbers. I take creatine and eat a high protein diet. My creatinine level averages around 116 but has occasionally spiked to above 1.3. The creatinine estimated eGFR comes back upper 60s/low to mid 70s. I added in the cystatin c estimated eGFR test and it came back 112 (cystatin c was .70). Really big difference! BTW, I had to have the test added. The primary care doctor wasn't aware of it.

 

[rixsternaz]

Prior to a blood test, I stop taking creatine supplements for one week to avoid any potential impact on the results. My results always have been in normal range for kidney function.

I also find that lab timing affects that creatinine quite a bit. I almost exclusively have draws done first thing in the morning (I already have my next three panels scheduled so that I get that first slot). But my eGFR will look a lot better if I do a draw at any other time of the day when I’m not as dehydrated as I am first thing in the morning.
