How do you take TRT?

For an overview of the full treatment approach and benefits, please refer to our treatment page.

Historical Context of Testosterone and TRT

Historically testosterone was associated with bodybuilders abusing vast quantities of anabolic substances often injected large bore into muscle. Abuse of these drugs and without proper monitoring can result in life complications. It is no therefore that the stigma associated with injecting testosterone into remains, albeit to a lesser degree as we are to shift the connotations the health and wellbeing benefits of TRT.

Methods of Administering TRT

There are ways of administering from injections to frequent using fine to oral .

The goal for most people is to find a treatment plan that provides them with stability in how they feel. Whilst an injection into muscle, like nebido, every 8 to 12 weeks is more convenient it has it’s drawbacks, primarily in that it does somewhat of a peak and a trough injections. The route to stability of levels is regular of fast but long acting testosterone esters like cypionate or pellets that slowly release testosterone, though there are also some practical with this method. Testosterone is suspended in low enough viscosity to be injected and drawn up using fine needles and of the lower it tends to be well tolerated when injected into the fat the skin (not dissimilar to the way is taken by patients with diabetes). This is often by as they can use fine needles and inject in the abdomen quickly, safely and in a fairly pain free way. Whenever you inject there will be a degree of and this applies to both muscle and fat. Scar tissue tends to be broken down and absorbed by the body, though this will happen at rates from one person to another, as will the of scar that forms vary. What’s is that when injecting into the fat, to give the body ample opportunity to clear the micro scar, your injection site trauma to the same piece of tissue. If the same tissue is repeatedly injected into scarring of the fat cells can become so marked that you can feel an area of hardness in your called . injecting into such an area would result in very little of the being by the body as it tends to remain in this walled off ball of fat.

As is the most effective means of taking TRT, avoiding forming scar tissue is a key . It’s not uncommon for patients who solely inject to some areas of that they can feel; it can feel like areas of hard or lumpy tissue. My advice is to rotate as much as possible, not just different sites for subcutaneous but also between subcutaneous and intramuscular injecting. using fine needles into the muscle, the thigh or the glutes, is an entirely different proposition to the large bore needle used by those .

Shelf Life and Sterility of Multi-Use Vials

Testosterone is most often in a multi-use vial that tends to last around 3 months. Questions have been raised about the sterility of a vial from which is drawn up repeatedly over a 3 month period. Whilst some state a 28 day use of vials, this is a fairly shelf life as there are that have found multi-use vials to be safe for at least 6 months when being drawn from twice daily.

Alternative Formulations of TRT

Other creams, which are to a greater degree than gels. They can either be applied to the skin or via a patch. These are largish molecules that need to navigate the fairly robust barrier, the skin. The skin’s also significantly depending on temperature, skin hydration, age, skin damage etc. Aside from absorption being an variable, of the drug from the patient to family and friends through direct or indirect is another problem. I advise with children in the household of this risk as it’s not for testosterone cream or gel to be found on bathroom or even transferred from shared towels.

The next area of interest is without a doubt testosterone in tablet form. Testosterone undecanoate has been as an oral version of TRT over many years, initially with liver issues when the drug would be metabolised. This has now been and there are agents available and whilst they’ve been used in the US for a few years, they are still fairly new to the UK market. The little research that’s been done shows good results with the oral forms, albeit they can take around a week to reach a stable level in the blood. Risk of the oral forms are similar to that of injectables and creams. The main with the oral has been how well they can be by the gut and the individual variability in the extent to which they get broken down by the liver when they pass through.

Finally, pellets might be the most fuss-free option on a day to day basis, where a small pellet that slowly testosterone constantly is just under the skin. It’s much more difficult with these to tweak protocols and if there are any concerns, whereas with the other forms you can simply pause treatment, it’s more of an to have to remove a pellet and then re-insert it.
