At a glance

• Forms / Cypionate is an oil-based intramuscular injection; 1.62% gel is a daily topical gel
• Cypionate dose / 50 to 400 mg deep gluteal IM every 2 to 4 weeks [1]
• Gel dose / Start 40.5 mg once daily; range 20.25 to 81 mg; titrate at about 14 and 28 days to 350 to 750 ng/dL [2]
• Boxed warning / None on the cypionate label; secondary exposure on the 1.62% gel label [1][2]
• Hematocrit / Mean rise +4.0% with IM enanthate/cypionate vs +3.0% with gel in a 29-trial network meta-analysis [3]
• Fertility / Both can reduce sperm production; the gel label says the effect may be irreversible [2]

Is there a standard switch schedule?

No switch schedule appears in either label's dosing information. The Depo-Testosterone label gives intramuscular dosing and says the half-life of testosterone cypionate after injection is about 8 days [1]. The 1.62% gel label gives a daily starting dose and says to check a pre-dose morning testosterone level at about 14 and 28 days [2]. Neither label describes a washout, an overlap, or a best day to start the new form.

Curtis Alexander on testosterone cream versus injection

Curtis Alexander, a pharmacist, argues that choosing between testosterone cream and injection depends heavily on the individual. He finds the cream easier to apply but warns that it can rub off on other people and is harder to dose precisely. He sees safety, effectiveness over time, and cost as roughly even between the two, while saying injections act much faster. He prefers small, frequent subcutaneous injections over a deep intramuscular shot given once a week or every other week, because frequent dosing mimics the body's natural pattern more closely. In his view, how a man feels about injections is the biggest factor in the decision.

What each label says

Depo-Testosterone (testosterone cypionate) is FDA-approved for primary and hypogonadotropic hypogonadism; safety and efficacy in age-related hypogonadism have not been established [1]. The label says to confirm low testosterone with morning serum levels on at least two separate days [1]. It specifies 50 to 400 mg every 2 to 4 weeks by deep gluteal intramuscular injection and states that it should not be given intravenously [1]. The label has no boxed warning [1]. It warns that testosterone can raise blood pressure and is not recommended in uncontrolled hypertension, and it lists polycythemia, venous thromboembolism, gynecomastia, and injection-site pain [1].

The gel information below comes from a generic 1.62% testosterone gel label (Padagis), the same strength as AndroGel 1.62%. It gives a starting dose of 40.5 mg (2 pump actuations) once daily in the morning, applied to clean, dry skin of the shoulders and upper arms and not to the abdomen, genitals, chest, armpits, or knees [2]. It allows adjustment between 20.25 mg and 81 mg daily based on a pre-dose morning testosterone level at about 14 and 28 days, with 350 to 750 ng/dL as the no-change range [2]. Its boxed warning reports virilization in children after secondary exposure and says that children should avoid unwashed or unclothed application sites [2]. The label also tells patients to wash their hands after applying, cover the site with clothing once the gel has dried, and wash the site before expected skin-to-skin contact [2].

What changes after a switch?

The main differences are in hematocrit, blood pressure and monitoring. In a network meta-analysis of 29 placebo-controlled trials and 3,393 men, mean hematocrit rose 4.0% with intramuscular enanthate/cypionate and 3.0% with gel versus placebo [3]. Intramuscular enanthate/cypionate rose significantly more than the patch, but the gel and intramuscular pair was not significantly different [3]. A retrospective review of 178 men found erythrocytosis (hematocrit above 50%) in 66.7% of men on injectable testosterone versus 12.8% on gels; the injection group was younger and had higher baseline hematocrit, so the comparison is not clean [4]. FDA says ambulatory blood pressure studies confirmed a blood pressure increase with all testosterone products [5], and the 1.62% gel label reports a mean 1.9/1.3 mm Hg rise at 16 weeks [2]. On fertility, the Depo-Testosterone label says large doses of androgens may suppress sperm production [1], and the gel label says reduced fertility is seen in some men and the impact may be irreversible [2].

TRAVERSE tested daily 1.62% testosterone gel in 5,246 men. MACE occurred in 7.0% of men receiving testosterone and 7.3% receiving placebo [6]. No outcome trial of that size exists for injectable testosterone [6]. The Depo-Testosterone label still carries older wording that studies have been inconclusive for MACE and that some, but not all, reported an increased risk [1].

What people on Reddit report

People who moved between testosterone injections and gel, describing why they switched and how the two felt different in daily life and in results.

I switched from gel to injections because on a sensory level I couldn't do "sitting around topless and slathered with cold sticky goo" every day. Plus it's expensive, plus my partner was worried about inadvertent exposure, plus it's inconvenient doing *anything* daily when weekly or less is an option.

Moved from gel to injections to avoid daily application, cost, and partner exposure concerns. Reports little difference in effects.

did gel > long acting injections > gel. Gel is nicer for my joints and emotional state, so I'm sticking with it. Only drawback is timing swim sessions, really

Moved from gel to long-acting injections and back to gel, and stayed on gel because it felt better for joints and mood.

ive only used gel the biggest thing is not everyone absorbs gel properly. if your levels are good and where they should be on gel then your fine. it does work a little slower at first but you wont get different results on shots UNLESS you just cant absorb it properly and your levels arent right.

Has used only gel. Says results depend on how well a person absorbs gel, and that gel works more slowly at first.

I don't find the gel as effective even tho everyone swears its fine (my dr agrees and says they see this issue a lot), but my levels are stable and it's something lol

Found gel less effective than injections for them, though their levels stayed stable. Disagrees with others who say gel works fine.

Frequently asked questions

›Can you switch from testosterone cypionate to AndroGel?

Neither label says when to start the gel after a cypionate injection. The 1.62% testosterone gel label describes a 40.5 mg daily starting dose and testosterone checks at about 14 and 28 days after starting [2]. The Depo-Testosterone label gives a half-life of about 8 days after intramuscular injection [1].

›Can you switch from AndroGel to testosterone cypionate?

Neither label says when to start cypionate after stopping the gel. The cypionate label gives 50 to 400 mg by deep gluteal IM injection every 2 to 4 weeks after low testosterone is confirmed on two morning tests [1]. The gel label's titration schedule applies to gel treatment [2].

›Is one form safer than the other?

They share class risks: blood pressure increases, polycythemia, venous thromboembolism, and possible reduction in sperm production [1][2]. The 1.62% gel has a boxed warning about secondary exposure and reported virilization in children; the cypionate label has no boxed warning [1][2]. Mean hematocrit rose slightly more with IM enanthate/cypionate than with gel in one network meta-analysis, but that pairwise difference was not significant [3].

What people actually ask

How is medical testosterone administered?

Medical testosterone is given two main ways in this article. Cypionate is an oil-based deep gluteal intramuscular injection of 50 to 400 mg every 2 to 4 weeks, and it should not be given intravenously. The 1.62% gel is applied once daily to clean, dry skin of the shoulders and upper arms, not the abdomen, genitals, chest, armpits, or knees.

Is one pump of testosterone gel enough?

No. The label's starting dose is 40.5 mg, which is 2 pump actuations, applied once daily in the morning. The dose can be adjusted between 20.25 mg and 81 mg daily based on pre-dose morning testosterone levels at about 14 and 28 days.

Is testosterone cypionate the same as AndroGel?

No. Testosterone cypionate is an oil-based intramuscular injection given every 2 to 4 weeks, while AndroGel 1.62% is a daily topical gel. The gel information comes from a generic 1.62% testosterone gel label (Padagis) with the same strength as AndroGel 1.62%.

How much will AndroGel increase testosterone?

No set amount is established for how much AndroGel will raise testosterone. Gel dosing is adjusted toward a morning testosterone level of 350 to 750 ng/dL, with levels checked at about 14 and 28 days after starting the 40.5 mg daily dose.
