What Is Testosterone Cream? Dosage, Half-Life & How to Track It
Also known as: AndroGel · Testim · Compounded Testosterone Cream · Transdermal Testosterone Gel
Testosterone cream delivers unesterified testosterone through the skin, applied once daily rather than injected weekly — there’s no oil-based ester to build a depot, so absorbed testosterone clears within a couple of hours and levels depend on the application happening every day. FDA-approved gels like AndroGel and Testim ship in pre-metered pumps or packets; compounded pharmacy cream is dispensed with a Topi-Click applicator, where one click delivers about 0.25 g of cream. Educational only; topical TRT dosing is set by your prescriber.
What testosterone cream is and how it works
Testosterone cream and gel deliver testosterone itself, not an ester — there’s nothing to cleave off before it becomes active, the opposite design from cypionate or enanthate. Applied to the skin (typically shoulders, upper arms, or abdomen), it’s absorbed gradually over several hours as the vehicle dries, entering circulation directly rather than through a depot injection.
That has two practical consequences. First, because there’s no depot, blood levels track the daily application rather than a weekly cycle — missing a day drops levels faster than missing a weekly shot would. Second, topical testosterone carries a well-documented transfer risk: skin-to-skin contact with a partner or child within a few hours of application can transfer meaningful testosterone, which is why labeling recommends covering the site, washing hands, and waiting before contact.
Two product families exist. FDA-approved gels (AndroGel, Testim) come from the manufacturer at a fixed concentration in a pre-metered pump or single-use packet. Compounded cream, prescribed through a compounding pharmacy, is custom-mixed to whatever concentration and volume the prescription calls for — and for that reason needs its own dosing math.
Dosing math: pumps, packets & Topi-Click
The commercial gels are the simplest to dose because the manufacturer fixes the mg per actuation: AndroGel 1% delivers about 12.5 mg per pump (a typical starting dose is 4 pumps, 50 mg); AndroGel 1.62% delivers about 20.25 mg per pump; Testim 1% comes in single-use 5 g packets containing 50 mg each. None of those require any calculation — the dose is simply the number of pumps or packets.
Compounded cream is different: the compounding pharmacy sets the concentration (written as mg/g or a %, e.g. 100 mg/g = 10%), and it’s usually dispensed with a Topi-Click dial-a-dose applicator, where each click reliably delivers about 0.25 g of cream. The formula is one line: mg per click = concentration (mg/g) × 0.25 g.
| Concentration | mg per click (0.25 g) | Clicks for 50 mg |
|---|---|---|
| 100 mg/g (10%) | 25 mg | 2 clicks |
| 150 mg/g (15%) | 37.5 mg | ~1.3 clicks |
| 200 mg/g (20%) | 50 mg | 1 click |
Compounded T cream concentration varies by pharmacy — always confirm the mg/g on the label before counting clicks. Women’s low-dose T cream is typically compounded far lower, around 10–20 mg/g (1–2%).
Half-life & why it’s applied daily
Testosterone itself, once absorbed, clears from the blood quickly — on the order of a couple of hours, the same fast clearance the hormone has any time it isn’t attached to a slow-release ester. That short window is exactly why topical testosterone is applied once daily rather than weekly: there’s no depot to coast on between doses.
The trade-off for daily application is a flatter, more consistent day-to-day pattern than a weekly injection’s peak-and-trough swing, but also more variable absorption from person to person — skin thickness, application site, sweating, and even temperature can change how much testosterone actually gets through on a given day, more so than with an injection.
What to track & precautions
Labs mirror any TRT protocol — total and free testosterone, estradiol, hematocrit, and a lipid panel — but timing guidance differs from injections: because there’s no weekly peak/trough, testosterone is typically drawn several hours after application rather than at a specific point in an injection cycle.
The transfer-risk warning is specific to topical testosterone and worth taking seriously: cover the application site with clothing, wash hands after applying, and avoid skin-to-skin contact with others — especially children and pregnant partners — for several hours. Local skin irritation at the application site is also common enough to be worth logging if it happens.
How to track Testosterone Cream in Stackeddd
Log each application the way you would an injection — date, dose (pumps, packets, or clicks), and site — so a daily-use compound doesn’t quietly slip the way something with no depot to fall back on can. If compounded cream is involved, run the concentration through the Cream calculator once and the click count for any target dose is locked in.

Frequently asked questions
How many clicks of testosterone cream should I use?
It depends on the compounded concentration: mg per click = concentration (mg/g) × 0.25 g, the standard Topi-Click volume. At 100 mg/g, one click delivers 25 mg; at 200 mg/g, one click delivers 50 mg. Always confirm your pharmacy’s specific concentration before counting clicks.
Is testosterone cream as effective as injections?
It raises testosterone through a different route — continuous daily absorption rather than a weekly depot — and can produce comparable levels, but absorption is more variable person to person than an injection, and daily application is easier to miss than a once-weekly shot.
Can testosterone cream transfer to other people?
Yes — skin-to-skin contact with a treated area can transfer meaningful testosterone to a partner or child, which is why labeling recommends covering the site, washing hands after application, and avoiding contact for several hours.
What is the half-life of testosterone cream?
Once absorbed, plain testosterone clears from the blood within a couple of hours — there’s no ester to slow it down. That’s why topical testosterone is applied once daily rather than weekly like an injectable ester.
