A 42-year-old man asks about low ferritin after a testosterone and Primobolan cycle. Dr. O’Connor asks about baseline ferritin, CBC results, iron saturation, gastrointestinal bleeding, and other medications before interpreting the finding.

01:30

Dr. O’Connor introduces Jardiance and its effects on hematocrit, then discusses competing influences on red blood cell production. He explains why CBC and iron studies should be reviewed together and highlights excessive phlebotomy as a possible contributor to low iron stores.

The discussion returns to the broader medical picture, including gastrointestinal bleeding, colon cancer family history, screening, and the ABCDs™ framework. Dr. O’Connor emphasizes that more information is needed for an individualized assessment.

Video Summary

A 42-year-old man reports low ferritin after a testosterone and Primobolan cycle. His bloodwork at 10 weeks otherwise looked reassuring, and he asks what caused the finding and how to address it. Dr. O’Connor emphasizes that ferritin alone is insufficient to determine the cause or choose a response.

He begins by asking about baseline ferritin, the complete blood count, iron levels, and iron saturation. He also raises gastrointestinal bleeding and other medications as possible contributors requiring further investigation.

The discussion expands to medications that affect hematocrit. Dr. O’Connor mentions Jardiance and explains that multiple influences on red blood cell production can complicate interpretation. He emphasizes reviewing the CBC alongside iron studies rather than focusing on one isolated result.

Dr. O’Connor describes stored iron being used to support increased red blood cell production during testosterone or anabolic steroid use. He distinguishes a modest decrease in ferritin from a broader pattern of low iron measurements and asks whether the man has been undergoing phlebotomy. Excessive phlebotomy is highlighted as a potential contributor to depleted iron stores.

He returns to the broader medical assessment, including gastrointestinal blood loss, family history of colon cancer, and appropriate screening. He references the ABCDs™ framework and concludes that additional laboratory results and medical history are needed before giving this man an individualized answer.

Drug Callouts

Testosterone

Testosterone is part of the reported anabolic steroid cycle. Dr. O’Connor discusses its relationship to increased red blood cell production and the use of stored iron, emphasizing interpretation of ferritin alongside the CBC and other iron measurements.

Primobolan

Primobolan, referred to as Primo, is described as a DHT-derived anabolic steroid used alongside testosterone. The combination provides context for the man's question, but Dr. O’Connor does not establish Primobolan as the specific cause of his low ferritin.

Jardiance

Dr. O’Connor discusses Jardiance as an SGLT2 inhibitor with heart and kidney benefits and effects on hematocrit. He introduces it as another influence to consider when interpreting red blood cell findings, without establishing that the man asking the question takes it.

Condition Callouts

Low Ferritin

Low ferritin is the laboratory finding reported by the man using testosterone and anabolic steroids. Dr. O’Connor emphasizes comparing it with baseline results, CBC findings, iron levels, iron saturation, and phlebotomy history before determining its significance.

Erythrocytosis

Erythrocytosis involves increased red blood cells and is discussed in relation to testosterone, anabolic steroids, and other medication effects. Dr. O’Connor emphasizes reviewing red blood cell findings together with iron studies and cautions about excessive phlebotomy.

Gastrointestinal Bleeding

Gastrointestinal bleeding is raised as a possible explanation for low iron stores in men using testosterone or anabolic steroids. Dr. O’Connor asks about blood loss rather than assuming the ferritin change is caused entirely by androgen use.

Colon Cancer

Colon cancer is discussed through family history and screening considerations. For men using testosterone or anabolic steroids who have low ferritin, Dr. O’Connor emphasizes including gastrointestinal health and family history in the broader assessment; he does not diagnose cancer in this case.

Key Takeaways

An isolated low ferritin result does not provide enough information to determine the cause or choose an appropriate response.
