Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Peak SX-7 contains 2 active ingredients. PEAK ATP is adenosine, a compound your cells naturally produce—it's used medically in its prescription injectable form to help diagnose heart conditions and treat certain irregular heartbeats.

Longjack extract comes from Eurycoma longifolia, a plant used in traditional medicine, often studied for effects on physical performance and sexual function. The product also contains inactive ingredients (maltodextrin, a capsule, magnesium stearate, and silicon dioxide) that serve as fillers and binders to hold the capsule together.

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: muscle strength and athletic performance.
  • We looked for evidence on: Muscle strength, Athletic performance, muscle hypertrophy, lean mass gain, exercise capacity.
  • The closest evidence on file: Eurycoma Longifolia is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Adenosine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.
  • Also on file: Eurycoma Longifolia is rated "Insufficient Reliable Evidence To Rate" for Muscle strength.

PEAK ATP (adenosine) is rated effective for diagnosing cardiovascular disease and for treating a type of irregular heartbeat called paroxysmal supraventricular tachycardia—but the data here reflects its powerful prescription injectable use under medical supervision, not this oral supplement form. Longjack extract is rated possibly effective for sexual desire.

For athletic performance, the evidence suggests it's possibly ineffective. For back pain, osteoporosis, and diabetes, there isn't enough reliable evidence to rate it.

The evidence, ingredient by ingredient Adenosine Eurycoma Longifolia

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Safety data on oral adenosine (PEAK ATP) as a supplement is limited. The prescription injectable form is powerful and works quickly—it can cause chest pain, dizziness, shortness of breath, facial flushing, headache, low blood pressure, nausea, and a racing or irregular heartbeat.

Serious effects are rare but can include cardiac arrest and heart attacks. Oral or intramuscular forms haven't shown reported adverse effects in studies, though thorough safety testing hasn't been completed.

Longjack extract is generally well tolerated short-term in studies, but long-term safety and product quality aren't certain. It may raise testosterone levels; if levels go beyond normal, you could develop acne, insulin resistance (trouble managing blood sugar), and liver damage.

The safety data advises against use during pregnancy and breastfeeding.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Adenosine, Eurycoma Longifolia.
  • The most serious interaction on file is rated Major.
  • For scale: 261 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Peak SX-7, check with your doctor or pharmacist if you're on dipyridamole (a heart medication causing a major interaction), carbamazepine (an anti-seizure drug causing moderate risk), or propranolol (a blood pressure medication causing moderate risk). Also let them know if you regularly consume caffeine, theophylline, or aminophylline, as these can interfere with adenosine's effects.

If you take any enzyme-processed medications or testosterone, mention that too—theoretically there's a minor risk, though it hasn't been confirmed in people yet.

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Peak SX-7 is an oral supplement form of adenosine and Longjack extract, designed to support athletic performance and sexual function, though evidence for the latter is modest and for the former is weak. If you take heart medications (especially dipyridamole or propranolol), anti-seizure medication, or drugs processed through your liver, or if you're pregnant or breastfeeding, check with your doctor or pharmacist before taking it.

The ingredients carry real interactions with common medications, so don't start Peak SX-7 without confirming it's okay for you.

General Statements

THE MOST POWERFUL NON-STIMULANT PRE-WORKOUT PILL

How Does It Work? Research suggests the key compound in Peak SX-7(TM)works using three distinct pathways. The first pathway helps increase blood flow to deliver more oxygen to hard-working muscles, allowing them to work even harder. The second mechanism of action is to help your muscles control ionic flux during contractions so they can recover and contract faster. The third and most important pathway of action is when Peak SX-7(TM) triggers the anabolic mTOR pathway – this puts your muscles in “musclebuilding” mode.

Subjects Gained More Muscle & Strength Than Subjects Using a Placebo in a 12-week Clinical Study Researchers at the prestigious University of Tampa conducted a randomized, double-blind, placebo-controlled clinical study done over 12 weeks on very well-trained athletes. 1Subjects gained 8.8 lbs. of lean muscle versus the placebo group, who only gained 4.6 lbs. The results were breakthrough!

Longjack extract5 drug types · 248 drugs

Propranolol (Inderal)

Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.

Likelihood Probable Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Testosterone

Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.

Likelihood Possible Evidence D
Longjack extract full monograph & interactions

PEAK ATP3 drug types · 47 drugs

Dipyridamole (Persantine)

Dipyridamole can increase the therapeutic and toxic effects of adenosine.
Dipyridamole decreases the metabolism of adenosine. Intravenous infusion of adenosine in patients who are taking dipyridamole can cause dizziness, bradycardia, and syncope. Dipyridamole should be discontinued for several days prior to a cardiac stress test using adenosine.

Likelihood Likely Evidence D
Carbamazepine (Tegretol)

Carbamazepine might increase the risk of heart block when used concomitantly with adenosine.
Carbamazepine and adenosine can both cause heart block. Giving them concurrently might produce an additive effect.

Likelihood Possible Evidence D
Methylxanthines

Methylxanthines are competitive antagonists of adenosine and can block its pharmacologic effects.
The methylxanthines, aminophylline, caffeine, and theophylline, can block the effects of adenosine by acting as competitive antagonists at adenosine cell surface receptors. It is recommended that methylxanthines be avoided for 24 hours prior to cardiac stress tests.

Peak SX-7 by MuscleTech: Common Questions

Does Peak SX-7 by MuscleTech interact with any medications?
Yes. Based on its ingredients, Peak SX-7 has a known interaction with 261 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Peak SX-7 contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is PEAK ATP?
PEAK ATP is adenosine, a compound your body makes naturally. Doctors use the prescription injectable form to diagnose heart problems and treat certain irregular heartbeats. This supplement is an oral form of that same ingredient, but the safety and strength data are different from the prescription version.
What does Longjack extract do?
Longjack is an extract from Eurycoma longifolia, a plant studied mainly for sexual function and athletic performance. The evidence supports it as possibly effective for sexual desire, but for athletic performance the evidence suggests it doesn't work, and there isn't enough data on back pain, osteoporosis, or diabetes.
Can I take Peak SX-7 while pregnant or breastfeeding?
The safety data advises against both. There isn't enough information on adenosine safety in pregnancy or breastfeeding, and Longjack extract carries safety concerns (including possible hormonal effects) that make it best to avoid during pregnancy and breastfeeding. Talk with your doctor or pharmacist about whether this product is right for you.
What are the side effects?
The prescription injectable form of adenosine can cause chest pain, dizziness, shortness of breath, facial flushing, headache, low blood pressure, nausea, and irregular heartbeats. Serious effects like cardiac arrest are rare. Oral adenosine hasn't shown reported side effects in studies, though full safety testing is incomplete. Longjack extract may raise testosterone, which could lead to acne, insulin resistance, or liver issues if levels get too high.
Will caffeine interfere with Peak SX-7?
Yes—caffeine and other methylxanthines (like theophylline in some asthma medications) can block adenosine's effects. If you're taking Peak SX-7, it's recommended to avoid caffeine for 24 hours beforehand, especially if you're about to have any adenosine-based heart tests.
Does Peak SX-7 have any fillers?
It contains inactive ingredients: maltodextrin, magnesium stearate, silicon dioxide, and a capsule material. These are standard binders and fillers that help make the capsule, not active ingredients.
