One of the first things you will be faced with, as you embark on TRT treatment, will be the choice between injections and gel. Both of these solutions are known to be quite effective. They vary greatly, however, in terms of cost, convenience, and lifestyle impact.
Testosterone Injections
The most frequent method of TRT is injectable testosterone, usually cypionate or enanthate.
How It Works
Testosterone is given through intramuscular injection (in the thigh, buttock, or deltoid muscle) or subcutaneously (in fat tissue). Gradually, the hormone will be absorbed into your bloodstream over several days.
Typical Protocols
- Weekly: Most common, provides stable levels
- Twice weekly: More balanced levels, preferred by most people
- Every 2 weeks: Less common due to hormonal fluctuations
Advantages of Injections
- Cost-effective: Generally the cheapest option long-term (£30-60/month)
- Reliable absorption: A full dose is absorbed by your body
- Flexibility: Easy to adjust dosages
- No transfer risk: No risk of transfer to partners or children
- Less frequent: Only 1-2 times per week compared to daily
Disadvantages of Injections
- Needles required: Some people have difficulties with self-injection
- Peaks and troughs: Fluctuation of hormones between injections
- Injection site reactions: Occasional soreness or irritation
- Travel considerations: Need to carry supplies when travelling
Testosterone Gel
Topical testosterone gel (such as Testogel, Tostran) is a daily topical treatment.
How It Works
It is applied to the shoulder, arm, or stomach regions. Testosterone takes several hours to be absorbed into the bloodstream from the skin.
Advantages of Gel
- No needles: Simply apply to skin daily
- Stable levels: Because testosterone is applied topically everyday, it leads to stable hormone levels
- Easy to adjust: Can modify dose by applying more or less
- Mimics natural production: Once a day application, just like naturally produced hormones
- Travel-friendly: Convenient to transport compared to injection supplies
Disadvantages of Gel
- Transfer risk: Can be transferred to partners, children, or pets through skin contact
- Variable absorption: The absorption rate varies among persons (10-35%)
- Daily commitment: It has to be applied everyday at the same time
- Skin irritation: Some people experience irritation, redness, or itching
- Higher cost: Typically £80-150/month
- Activity restrictions: Must wait before showering, swimming, or contact with others
Cost Comparison
| Method | Monthly Cost | Annual Cost |
|---|---|---|
| Injections (Cypionate/Enanthate) | £30-60 | £360-720 |
| Gel (Testogel/Tostran) | £80-150 | £960-1,800 |
| Nebido (every 10-14 weeks) | £60-100 | £720-1,200 |
Lifestyle Considerations
Choose Injections If:
- Budget is an important consideration
- You're comfortable with needles (or you're learning to be)
- You have a partner or young children (no transfer risk)
- You prefer less frequent administration
- You want guaranteed absorption
Choose Gel If:
- You have a strong aversion to needles
- You live alone or can easily avoid skin contact for a few hours
- You like the regularity of daily application
- Budget is less of a concern
- You travel frequently and your lifestyle requires simplicity
What About Absorption Issues?
In some men, the absorption of gel can be poor. Symptoms of poor absorption include:
- Lower levels of testosterone even with proper use
- Failure of symptoms to improve within 4-6 weeks
- Requiring maximum doses of the gel to reach normal levels
If this happens, a transition to injection delivery might solve the problem.
Conclusion
Neither option is objectively "better" than the other, and which one is best for you will depend on your lifestyle needs and preferences. Some guys will start out using one and then switch to the other. The most crucial part is simply finding something that you can stick to and keep your levels in balance.
