What it actually is
Testosterone cream is the same testosterone molecule found in Forge — pharmaceutical-grade, identical to your body's own — formulated into a transdermal cream base instead of an oil-based injection.
You apply a measured dose to clean, dry skin every morning. The skin absorbs a fraction of it across the day, releasing testosterone slowly into the bloodstream. The result: a flatter, smoother serum-T curve than any injectable can produce.
Cream gives you the smoothest possible levels. No peak on day 3, no trough on day 7 — just a steady, in-range number, every day, every hour.
How transdermal works
Skin is a barrier, not a wall. The outer layer (stratum corneum) is the bouncer; the deeper layers happily absorb lipid-soluble molecules. Testosterone is lipid-soluble. The cream base — a mix of penetration enhancers and emollients — temporarily relaxes the barrier just enough to let testosterone diffuse through.
Once across, it enters the dermal capillaries and joins your bloodstream. Levels rise within 2–4 hours, peak in the early afternoon, and gently descend overnight — closely mimicking the natural diurnal rhythm of male testosterone production.
Dose
Ember starts most men at 0.5 mL daily — that's 100 mg of testosterone in solution, of which about 10–14% (10–14 mg) actually crosses the skin. That sounds small; it isn't. Your testes make about 6–7 mg of testosterone a day. The cream replaces and exceeds that.
| Starting dose | Target Total T | Adjustment cadence |
|---|---|---|
| 0.5 mL daily (am) | 650–900 ng/dL | Week 8 + Week 16 |
How you take it
- Pump 0.5 mL onto two fingers (it's measured for you — one click of the metered pump = one dose).
- Rub into clean, dry skin on the inner upper arm or shoulder. Both arms.
- Wait 2 minutes. Get dressed.
- Don't shower or swim for 4 hours. Don't let your partner or kids touch the application site for 2 hours.
Total time: 90 seconds.
Side effects, honestly
- Skin transfer. The single most-cited concern. If a partner or child rubs against the still-wet site, they get a small dose. Real but rare — under 1.5% of patients in our cohort. Solution: dress, wait, wash hands.
- Application-site reactions. Mild redness or itching, usually resolves within a week or two of starting.
- Same hormonal side-effect profile as injectable T (hematocrit, estradiol, sperm suppression) but generally milder, because the curve is flatter.
Who it's right for
- Men who don't want to inject anything, ever.
- Men whose mood, libido, or energy swing hard between injection peaks and troughs — cream eliminates the swing.
- Men who travel constantly. A cream tube is TSA-compatible. Vials and syringes get questions.
- Men with partners who are needle-phobic or grossed out — the cream is invisible.
Who it's wrong for
- Men with very low SHBG who need a steeper curve to feel anything (rare; bloodwork tells us).
- Men who live in close, skin-on-skin contact with infants or pregnant partners — risk:benefit shifts.
- Men actively trying to conceive in the next 12 months. Sperm suppression still happens, just slower.
What we monitor
Same panel as Forge — Total T, Free T, SHBG, Estradiol-sensitive, Hematocrit, PSA, Lipids, Liver. Baseline, week 8, week 16, quarterly. Cream tends to show smaller hematocrit elevations than injectable, but we still measure.
Cream is the smoothest curve we can produce. It's also the protocol most often chosen by physicians for themselves — because once you've tried both, you'll likely want both.— Dominant clinical team
The bottom line
If you want optimized levels without needles, without peaks, and without the rhythm of weekly injections — cream is the answer. Same molecule. Different delivery. Real, measurable, supervised.
