T-Base has been discontinued. Check out BPS Dermacrine as a T-Base alternative.
Muscle Research’s T-Base (Testosterone-Base) is a topical pro-steroid cream that combines precise amounts of DHEA (dehydroepiandrosterone, 3b-hydroxyandrost-5-en-17-one) and 1-DHEA (1-Androsterone, 3b-Hydroxy-Androst-1-ene-17-one), along with anti-estrogens, a neurosteroid and DHT inhibitor. These active ingredients are immediately delivered directly to the blood stream via T-Base’s advanced transdermal delivery system. Our unique transdermal delivery system enhances the absorption, uptake and efficiency of the ingredients in T-Base, making it up to 20 times more effective than oral supplements (tablets/capsules). This in turn, enhances performance, increases lean muscle, increases strength, reduces body fat and improves overall body composition. Advantage, YOU!
If you are supplementing DHEA, or thinking of supplementing DHEA, you want to be sure to use a transdermal preparation. Studies have shown that transdermal DHEA has a relatively high bioavailability. In fact, oral DHEA only has 10-15% of the bioavailable activity as the transdermal DHEA in T-Base! If you are supplementing with Oral DHEA, you are wasting a large amount of hormones and you are throwing money away. The advanced transdermal delivery system in T-Base ensures your body converts a much higher amount of anabolic and androgenic hormones. This is why you want T-Base!
T-Base is one of the most powerful prohormone products legally available today. Even a 5 week cycle of T-Base can provide significant gains in size and strength. A user could expect gains of up to 6 to 10 pounds (or more) of lean body mass, with little to no side effects due to the specific combination of ingredients to block estrogen and control DHT.
Most people are familiar with DHEA (androstenolone). DHEA and its supplementation in humans, has been studied for decades. DHEA is the body’s natural steroid hormone precursor. Powerful anabolic and androgenic hormones, such as androstenediol, androstenedione and testosterone are converted from DHEA.
Why choose T-Base?
DHEA has been used by the anti-aging crowd as early as the 1980’s, for its abilities to increase strength and energy, burn fat, improve libido and sexual performance, promote an enhanced sense of well-being, improve recovery from exercise and immune system function, and provide a noticeable improvement in body composition, even without changes in diet or exercise.
Though T-Base’s transdermal preparation provides the highest level of hormone bioavailability, DHEA still converts to testosterone at a relatively low rate. DHEA does have a high conversion to 5-androstenediol, which is where it gets most of its mild androgenic and anabolic effects. DHEA’s thermogenic fat burning properties come from its conversion to 7-oxo-DHEA.
DHEA rarely causes hair loss or acne, and although it has moderate estrogenic effects, it rarely produces gynecomastia (gyno) or other unwanted estrogenic side effects. Transdermal DHEA applications have actually shown in studies to have no significant increase in serum estrogens. Studies using oral DHEA however, have shown significant increase in circulating estrogens. The inclusion of anti-estrogens and a DHT inhibitor in T-Base further reduces any probability of these negative side effects. T-Base has you covered!
1-DHEA (1-Androsterone) is a pro-steroid that must convert to one of the highly anabolic and androgenic, 1-androstenediol (1-AD), 1-androstenedione (original 1-AD) and/or 1-testosterone to be active. T-Base’s transdermal delivery system improves these conversions due to the high concentration of steroidogenic enzymes in the skin compared to the digestive tract. Once in its final form, this compound has about the same androgenic potency of testosterone, with twice the anabolic potency (100:200 vs 100:100).
1-DHEA primarily converts to the potent 1-androstenediol (1-AD), and it does not convert to estrogen nor does it activate the estrogen receptor. It is noted for producing moderate gains of lean muscle mass and strength, increased muscle hardness, enhanced recovery, more intensive workouts, and a slight decrease in body fat.
1-DHEA is a naturally occurring, non-toxic, safe, legal and effective lean muscle building agent. It is a “dry” compound, meaning that it does not produce water retention or bloat, nor is it likely to have a dramatic effect on blood pressure. Users should not experience gynecomastia since there is no conversion to estrogen. Reports of hair loss or thinning are minimal with 1-DHEA, and practically non-existent with T-Base’s inclusion of anti-estrogens and a DHT inhibitor. Probably the most common side effect users have reported with 1-DHEA is a feeling of lethargy. However, with the anti-lethargic effects of DHEA and Pregnenolone in T-Base, this 1-DHEA side effect should be eliminated. T-Base’s transdermal delivery system also eliminates liver first pass, providing relief from the worries of liver stress.
T-Base also includes the hormone Pregnenolone, the “grandmother” or primary hormone to all hormones. Pregnenolone cream is often prescribed as part of a HRT regimen, to control DHT conversion and help prevent hair loss in men prone to androgenic alopecia. Pregnenolone is also a powerful neurosteroid. In conjunction with DHEA, Pregnenolone further enhances cognitive effects, focus, memory and sense of well-being.
A composite of the anti-estrogen ingredients resveratrol, 7,8 benzoflavone and chrysin, round off the active formula of T-Base. These natural compounds can bind to the estrogen receptor and block estrogenic activity. Resveratrol, 7,8 benzoflavone and chrysin have also been shown to support healthy blood vessel function, improve libido, increase testosterone levels, fertility, and erection strength.
What kind of results can I expect from T-Base?
Results from T-Base can begin to be felt within a few days and become more pronounced and noticeable within a couple of weeks. Of course results will vary based upon the dosage and the user’s experience, diet, rest and effectiveness of workouts. T-Base users can expect enhanced cognitive effects, focus, memory and sense of well-being, increased energy and strength, improved libido, sexual performance, and erection strength, moderate gains of lean muscle mass, increased muscle hardness, enhanced recovery, more intensive workouts, decrease in body fat, and a noticeable improvement in body composition.

What is in T-Base?
1 pump per serving
69 servings per bottle:
1-Andro, 3b-Hydroxy-Androst-1-ene-17-one 50mg
Do I need Post Cycle Therapy after using T-Base?
YES. A full PCT is always recommended when using T-Base, since it is supplying the body with an outside source of hormones, and suppressing the body’s natural production of hormones. We recommend the Perfect Post Cycle Therapy Stack, by MR Supps.
What side effects can I get when using T-Base?
Side effects with T-Base should be mostly non-existent due to the completeness of the formula. Aside from the suppression of your body’s natural hormone production, using T-Base within the recommend dose is safe for men, granted there are no serious pre-existing medical conditions. The most likely side effects that could be reported would possibly be skin irritation and/or mild anxiety. These side effects are not very likely, and any mild anxiety should generally be avoidable if the user is participating in moderate physical activity on a daily basis. If any side effects do occur, use of T-Base can be stopped or reduced and the side effects should disappear quickly.
There is a risk of T-Base transfer to others who come in contact with the application site for up to 12 hours after application. Secondary exposure can be mitigated by means of a t-shirt barrier.
Do I need an AI (Aromatase Inhibitor) when using T-Base?
Typically, no you do not. T-Base has an anti-estrogen complex built into the formula. When building a cycle and a PCT, it is always wise to have an AI handy. We highly recommend our extremely potent and effective Forma Stanzol v3, not only for on cycle support, but for use in PCT, to enhance recovery by stimulating LH, FSH and natural testosterone production.
Will taking T-Base give me gyno?
Since T-Base does not convert to estrogen and has estrogen blockers built into the formula, gynecomastia (gyno) should not be a major concern. If you are highly prone to Gyno it is suggested to use Forma Stanzol v3 for the entire cycle.
Is T-Base liver toxic?
T-Base is a transdermally applied product that contains non-methylated (non 17aa) pro-steroid ingredients, so it isn’t inherently toxic to the liver. Furthermore, due to the advanced transdermal delivery system, most of the conversions to the anabolic/androgenic hormones such as, 5-androstenediol, 1-androstenediol/1-androstenedione (1-AD) and/or 1-testosterone, are taking place via steroidogenic enzymes in the skin, so liver stress should be virtually eliminated. Studies have also shown no significant elevation in liver enzymes with transdermally applied DHEA hormones.
I’m under the age of 21, should I use T-Base?
No. In fact, you should not use any steroid or hormonal product if you are under 21. Your body is already making plenty of natural Testosterone at your age and there is no need to mess with hormonal products.
I’m an athlete in organized sports, should I use T-Base?
No. Using T-Base to enhance athletic performance in competitive sports is morally wrong and against the rules of every known organized sports league. Cheating in sports by a few, is the main reason Steroids are illegal for all of us. Not only are you cheating yourself, but you are also going to get caught. T-Base will make any drug-tested athlete test positive for WADA banned substances during the cycle.
What is the recommended usage for T-Base?
It is recommended to apply 1 pump twice daily for 5 weeks to upper back, shoulders, or arms.
The caliber of effects is dependent on the dose/amount used. It is best to start off with a lighter dose and increase as needed. It is not suggested to apply more than three (3) pumps of T-Base in a 24hr period.
More experienced users should feel comfortable experimenting with cycles of up to 8-10 weeks of continuous use of T-Base. In case of accidental overdose, contact a health care professional or poison control center immediately.
A PCT is always recommended when using T-Base, since it is supplying the body with an outside source of hormones, and suppressing the body’s natural production of hormones. We recommend the Perfect Post Cycle Therapy Stack, by MR Supps.
