Testosterone Replacement Therapy

Treating low
testosterone, the right way

Declining Testosterone can put your life on a halt, but it doesn’t have to. There are scientifically proven options available!

Get Started

Statistics and symptoms

Living with low T is tough.

Chronic Fatigue

Low testosterone often leads to low energy, constant fatigue, and an overall lack of interest in daily life.

Muscle Weakness

Low Testosterone can result in reduced endurance, loss of muscle mass, and poor performance.

Mood changes

Low testosterone leads to significant mood swings, resulting in depression and anxiety.

Low libido

Low testosterone can reduce your ability to have satisfying intercourse, adversely impacting intimate relationships.

Erectile Dysfunction

Low testosterone is a leading cause of the inability to maintain an erection sufficient for intercourse.

Brain Fog

Low testosterone levels can lead to decreased cognitive function, and difficulty concentrating.


The Science: It is a long acting testosterone ester that metabolizes in approx. 7-8days. It is bio-identical and works best to treat chronic low testosterone.


Results6-8 weeks

UsageInject 1-3 times weekly intramuscularly

Why TRT?

Increased muscle mass and strength

TRT can increase muscle mass and strength, leading to improvement in athletic performance and physical functioning in men with testosterone deficiency. The mechanisms by which TRT increases muscle mass and strength are thought to involve stimulation of satellite cells and promotion of protein synthesis, among other factors.

Improved sexual function​

TRT can improve sexual function by increasing libido and reducing erectile dysfunction in men.This may be due to the testosterone's ability to improve penile dilation, and stimulate sexual desire.​

Better bone health

Testosterone plays an important role in maintaining bone density and preventing osteoporosis. TRT can help to prevent bone loss and reduce the risk of fractures in older men.This may be due to testosterone's ability to stimulate bone formation and inhibit destruction of bone mass and density.

Enhanced mood and well-being

Testosterone has been shown to have a positive effect on mood and well-being, and TRT has been used to treat depression and anxiety in men. It can also improve energy levels and overall quality of life by regulating neurotransmitter levels, among other factors.

Francis Major

I recently reached out to OnMen after blood work showed my T was at the low end. I like that OnMen won't prescribe TRT unless they deem it necessary and they will suggest alternative options if you don't qualify.

Joseph Bartek

So grateful to have found this company. A Lot of physicians in Canada still feel it is a waste of time to even look at optimizing testosterone, especially because reference ranges are so diverse.The doctor that OnMen provided was knowledgeable and patient. The best part was she listened to what I had to say instead of just trying to prescribe an antidepressant. Very satisfied, very greatful

Deven MacDonald

Finally a legit TRT clinic in Canada I've had a really good experience with Onmen. The blood test that they do every three months is really superb. The clinicians are well versed in hormone optimization and I've appreciated their services immensely. The prescription comes directly to my door, and it's done wonders for me and my overall quality of life.

NLHRX L- Google

OnMen has been amazing, and has given some of the best customer service I have seen. The technician is very knowledgeable, and they take a very responsible and ethical approach towards trt.They believe in making actual long term improvements, and will not just jack you full of test. They will not prescribe if you don't need it, and will slowly ease you into the treatment protocol if you do.Amazing company!

Shawn Guild

I had been looking for a clinic that treats hormones for men under 40 for 3 years. Getting turned down left right and centre by under educated physicians because of my age (now 31). I finally found ONMEN, I am truthfully so impressed with their team of customer service reps, managers and nurse practitioners. Everyone has been so helpful and eager to answer my MANY many (I’m sure annoying at times) questions.

Langley Jackson

Super easy to do business with. No pushy sales tactics. Incredibly easy to get a hold of as well. The chat window is answered by an actual person. Professional all the way through the process. Can't recommend enough!

Arthur Tutt

5 Stars. Very helpful and attentive. I had a flight coming up for long term travel where I was going to be out of the country for a few months and OnMen was very accommodating to make sure I got scheduled in early for an appointment with enough time before my flight to get the necessary bloodwork done and get the TRT prescription. Easy to work with. Very smooth. Thank you so much!!

Filling in our online health assessment is the first step. Once complete, we’ll send you a referral for the Low T blood work panel.

Getting your sample back to us as soon as possible is vital. We can’t schedule your initial virtual consultation with a Science&Humans clinician until the blood work is complete.

Personalized, individual healthcare plan

Once your blood results have been analyzed, you’ll have an in-depth video consultation with a licensed Science&Humans clinician.

They’ll spend time getting to know you as an individual, explain your results and what they show, and recommend a personalized treatment plan, specific to your needs.


Your personalized medication will ship directly to your door every three months for free, through one of our licensed partner pharmacies. It’s a no-fuss, all-around approach to your healthcare.

Quarterly follow-ups

We’ll conduct repeat blood work-ups every 3 months during your treatment. There’ll also be a virtual follow-up consultation with one of our providers after each set of results. We use these quarterly checks to track your ongoing progress and make any necessary tweaks to your treatment.

This system ensures continued, relevant care, tailored specifically to keep you performing at your best.

Your Science&Humans TRT subscription includes a follow up blood work requisition and review of the blood work/your progress during a live follow up consultation, every 3 months. If you are not experiencing any side effects, the practitioner will renew your prescription. Please note that this does NOT include the cost of medication, that is paid directly to the pharmacy.

The personalized treatment, including your specific dosage, will be determined by your Science&Humans clinician during your initial virtual consultation.

Your TRT prescription comes in a range of options. We offer a specially made testosterone formulated cream as well as injections and gels.

TRT treatment is prescribed solely at the discretion of the clinician, based on an extensive analysis of your blood results and symptoms.

Yes, TRT may affect fertility. If fertility is of concern for you, please refer to our hCG program.

Human Chorionic Gonadotropin (hCG) plays an essential part in Testosterone production. But it can also help keep the side effects of Testosterone treatment at bay.

Specifically, hCG can boost the production of sperm and Testosterone in the testicles, which in turn can maintain and increase fertility.

It can increase testicle size, but it’s also a proven method for treating Low T for those who want to preserve their fertility during treatment.

All care decisions are made by the independent clinicians who work with you, based on your test results. So, if your blood work doesn’t indicate Low T, we won’t treat you for it.

We work based solely on medical needs and nothing else.

If you have already been issued the blood work requisition, the $50 is non-refundable. If your appointment has taken place and a prescription was offered, the $150 is non-refundable.

However, if during the initial virtual consultation, both you and the clinician decide that TRT isn’t the right option for you, we’ll absolutely refund the cost of the appointment.

First-time blood work requisitions are sent within 24 hours of sign up.

Follow-up requisitions are sent 70 days from your last shipment of medication.

Blood work should be completed in the morning, before 10am.

Once you have qualified as eligible to receive TRT, payment will be deducted for your initial virtual consultation..

Payment for quarterly follow-ups and blood work will be deducted every 70 days.. This means we can have everything in place for your next set of blood work and appointments.

The process starts as soon as we receive your blood work. Once the extensive analysis is complete, you will have a decision on your eligibility in 5-10 working days from receipt of your results.

It couldn’t be simpler. Start by checking out for TRT for $50. You’ll need to complete the blood work, as usual, so we can see where you’re at, levels-wise.
