Is Clomid (clomiphene citrate) a good alternative to TRT for men with low testosterone? Clomiphene can raise testosterone levels while preserving fertility—making it attractive for younger men who want to avoid testicular shutdown. But new research suggests we should be monitoring IGF-1 levels...

* Standardization and harmonization offer the possibility to make laboratory test results more comparable. Standardization refers to the process of achieving agreement between hormone tests by establishing traceability to a recognized standard reference material through a high-order primary...

Abstract Kisspeptin-10 is a peptide hormone capable of increasing circulating follicle stimulating hormone, luteinizing hormone and testosterone levels in humans. Clinically, these effects suggest its use as a treatment for infertility. However, its testosterone-increasing effect indicates...

Started TRT 2 weeks ago-Transdermal Gel once per day in AM. I will need to have blood work done in a few weeks. My question is about the timing of testing for Testosterone in relation to taking the dose. Since i apply the dose at 8 am daily, if i test the next day at about 8 AM before taking...

Has anyone tested the hcg from reliablerx? I’ve seen quite a few people on here say great things but wanted to know about testing.

So While on TRT since we are using exogenous Injections we don’t need to fast before a test for testosterone or free testosterone right ? I’m not doing any lipid panels or anything

I'm sure it is technically challenging and prohibitively expensive, but I wish there was a cost effective machine that could test TT, FT, and/or E2 at home. You can get a hematocrit testing machine for about $150 on Amazon. Obviously glucose testing. I would think the market for at-home T...

I'm having some trouble understanding how different ranges relate to each other. For example, the non-Dialysis Free T mehod at Quest has a range of 46-224pg/mL for 18-69yo males (Quest Diagnostics: Test Directory). However the Dialysis Free T range shows 35-155pg/mL on my lab report. My...

Has anyone tested thyroid hormones using LC/MS-MS instead of immunoassay testing? I read a study about the inaccuracy of the immunoassay when testing levels in the lower part of the range especially for free t3. My most recent free t3 level by immunoassay was 2.5pg/ml range 2.0-4.4pg/ml. With a...

The consensus of opinion from most practitioners is to NOT take your med for at least 7 hours prior to lab draw. I had always taken my morning dose about 2 hours before draws and likely received misleading serum levels until I recently changed to taking my last dose about 15 hours prior to the...

Hi All - FYI: I did some shopping around and this is the place where I've consistently found the best pricing on labs. You can choose to go to either a Quest or LabCorp collection center. No Dr. Rx needed and I always check the "weekly promotions" where sometimes you'll find packages at discount...
