Blackstone Labs | BSL Isolation Protein
$49.99

Harmonize focuses on libido, mood, circulation, and hormonal support, not muscle protein synthesis. Pairing it with a high-quality whey isolate covers the recovery side of the equation so improved drive and training consistency are backed by adequate amino acid delivery.

Use Harmonize earlier in the day or pre-activity; use whey protein post-workout or anytime daily protein intake is low.

Creatine monohydrateSTRENGTH

Creatine complements Harmonize well because the two products solve different problems. Harmonize targets vitality, drive, and endocrine support, while creatine improves phosphocreatine availability for repeated high-output efforts and long-term strength performance.

Take Harmonize as directed; take creatine daily at any time, ideally with a meal or post-workout shake.

Fish oilGENERAL WELLNESS

Omega-3s pair well with a formula that includes turmeric and is aimed at users dealing with stress, training load, or age-related decline in vitality. Fish oil adds additional support for inflammation balance, cardiovascular health, and overall recovery capacity.

Take fish oil with meals; Harmonize can be taken earlier in the day or pre-activity.

Magnesium glycinate or ZMA-style recovery supportSLEEP

If low drive is being amplified by poor sleep quality, a nighttime mineral or recovery formula can make Harmonize work better in the bigger picture. Better sleep and nervous system recovery improve the environment in which libido, mood, and hormone-support ingredients operate.

Take Harmonize during the day; take magnesium or ZMA-style products 30-60 minutes before bed.

Full Product Description Article

Blackstone Labs Harmonize is a proprietary-blend hormone and vitality formula built around three overlapping goals: support libido and sexual wellness, enhance mood and drive, and influence hormonal balance through a mix of botanicals, neurotransmitter-active compounds, circulation support, and hormone-related actives. This is not a basic adaptogen formula. It is a more aggressive, old-school capsule product that combines libido herbs like maca, epimedium, and damiana with fast-feel compounds like beta-phenylethylamine HCl and mucuna pruriens, then pushes deeper into endocrine territory with DHEA and androsta-3,5-diene-7,17-dione. The strategy is clear: create a product you feel, not just one you take on faith.

The biggest strength of the formula is its broad mechanism coverage. Maca 4:1 root is here as a concentrated libido and vitality botanical. Human data on maca commonly uses roughly 1.5-3g of raw powder daily, so concentrated extracts are often used to deliver a similar traditional effect in less capsule space. Customers typically look to maca for improvements in sexual desire, mood resilience, and overall sense of vitality rather than an acute stimulant-like effect. Beta-phenylethylamine HCl is a rapid-onset neuromodulator often associated with elevated mood, motivation, and a noticeable lift in mental drive, although its effects are usually short-lived because it is rapidly metabolized.

Mucuna pruriens standardized to 98% L-DOPA is one of the more pharmacologically active botanicals in the blend. L-DOPA is a direct precursor to dopamine, which helps explain why mucuna is often used in formulas targeting motivation, libido, and reward signaling. That can translate into a stronger sense of drive and interest, especially when paired with beta-phenylethylamine. Epimedium extract standardized to 10% icariin and damiana extract continue the libido-support angle. Icariin is commonly discussed for its role in sexual wellness and circulation-related support, while damiana has a long traditional history in desire and mood formulas.

Sodium nitrate adds a separate dimension by supporting nitric oxide production and blood flow. That matters because circulation is a practical part of sexual performance and physical readiness, not just a gym performance issue. Turmeric standardized to 95% curcuminoids brings an anti-inflammatory counterbalance to the formula, although curcuminoids generally perform best when paired with a dedicated absorption enhancer, which is not disclosed here.

The most consequential ingredients are DHEA and androsta-3,5-diene-7,17-dione. DHEA is a steroid precursor with moderate evidence. Meta-analytic data shows that doses above 50mg per day are more likely to raise testosterone than lower doses, and DHEA also acts as an estrogen precursor, especially relevant in women. Importantly, DHEA is not a body-composition shortcut; meta-analysis does not support major fat-loss or recomposition effects on its own. Androsta-3,5-diene-7,17-dione is typically used in estrogen-management style formulas because it is intended to influence aromatase activity, but this is precisely the kind of ingredient where undisclosed dosing matters.

That brings us to the formula’s biggest limitation: transparency. Harmonize uses a 2.9g proprietary blend across nine actives, which means no customer can verify whether maca is meaningfully dosed, whether mucuna is aggressive or conservative, or whether DHEA is in the range used in research. In a category with hormonally active compounds, that lack of clarity matters more than it does in a simple herbal formula. Still, the ingredient architecture is coherent. Day 1, users are most likely to notice mood, drive, and possibly circulation-related effects. Over 2-4 weeks, the intended experience shifts toward more stable libido support, endocrine support, and a more noticeable baseline sense of vitality. The formula concept is compelling; the proprietary blend is the tradeoff.

Science & Clinical References 11 citations
DHEA and Endocrine Positioning5 studies

DHEA is an endogenous steroid precursor that can feed into downstream androgenic and estrogenic pathways depending on tissue context, enzyme expression, age, and baseline status. In supplementation, its utility is usually framed around restoring or supporting a declining hormonal environment rather than producing an acute stimulant-like effect. The clinical literature is mixed, but evidence is strongest in populations with lower baseline DHEA status or age-related decline. Because endocrine conversion is individualized, response variability is substantial and caution is warranted in hormone-sensitive users.

Mucuna, L-Dopa, and Motivation Signaling2 studies

Mucuna pruriens standardized to L-Dopa can influence dopaminergic tone by supplying a direct biochemical precursor to dopamine synthesis. Dopamine pathways are closely linked to reward anticipation, motivation, sexual interest, and perceived drive, which helps explain the fast-feel character often attributed to this ingredient. This does not guarantee a dramatic effect in every user because neurotransmitter handling differs widely across individuals. In a mixed formula, mucuna is most plausibly contributing to the early uplift in interest, initiative, and central activation.

Maca as a Libido and Vitality Botanical2 studies

Maca is best understood as a functional vitality herb rather than a direct hormonal switch. Human data suggest benefits may emerge through influences on sexual desire, perceived well-being, and fatigue resilience without reliably changing classic serum hormone markers. That distinction matters because users may feel improvements in libido and vitality even when bloodwork changes are minimal. Concentrated forms are commonly used in capsule formulas to target these outcomes with less serving bulk.

Sodium Nitrate and Circulatory Support2 studies

Dietary nitrate can be reduced through the nitrate-nitrite-nitric oxide pathway, ultimately supporting vascular tone and blood flow under favorable physiological conditions. In practical terms, that may enhance the circulation component of arousal and support a more perceptible fullness or vascular sensation. The effect is mechanistically distinct from libido herbs and neuroactive compounds, making it a useful complementary pathway in a multi-target vitality product. Response depends on oral nitrate reduction, timing, and total dose, which is a limitation in proprietary blends.

All Questions About Blackstone Labs | Harmonize | 30 Capsules 10 Q&A
What is Blackstone Labs Harmonize designed to do? +
Harmonize is a capsule-based hormone and vitality formula designed to support libido, mood, motivation, circulation, and endocrine balance. It combines botanicals like maca, damiana, and epimedium with neuroactive ingredients like beta-phenylethylamine and mucuna, then adds DHEA and androsta-3,5-diene-7,17-dione for deeper hormone-support positioning.
How many capsules are in a serving of Harmonize? +
A full serving is 4 capsules, and each bottle provides 30 servings. The label also indicates users can take one to four capsules daily, which makes it reasonable to start low and assess response before using the full serving.
Is Harmonize a fully transparent formula? +
No. Harmonize uses a 2.9g proprietary blend that lists the ingredients in order but does not disclose individual milligram amounts. That means you cannot verify the exact dose of maca, mucuna, sodium nitrate, DHEA, or any other active in the blend.
Does Harmonize contain caffeine? +
No caffeine amount is listed on the verified label data. However, the formula can still feel stimulating because beta-phenylethylamine and mucuna pruriens can noticeably affect mood, motivation, and central nervous system tone.
What does the DHEA in Harmonize do? +
DHEA is a hormone precursor that the body can convert into downstream steroid hormones. Research shows DHEA can influence testosterone and estradiol levels, but the effect depends heavily on dose, and Harmonize does not disclose its exact DHEA amount.
Why is sodium nitrate included in a hormone-support formula? +
Sodium nitrate supports nitric oxide production and blood flow. That matters because sexual wellness is not only about desire and hormones; circulation is also a practical part of physical readiness and performance.
Can beginners use Harmonize? +
This is not the best starting point for beginners. The combination of proprietary dosing, hormonally active compounds, and stronger mood-drive ingredients makes it better suited to experienced users who understand their response to advanced supplements.
How long does Harmonize take to work? +
Some users may feel mood and drive effects the first day, especially from beta-phenylethylamine and mucuna. The broader libido and hormone-support goals are more realistically judged over 2-4 weeks of consistent use.
Can I stack Harmonize with a pre-workout? +
You can, but use caution. Even without disclosed caffeine, beta-phenylethylamine can increase the intensity of a stimulant-containing stack, so most users should start with conservative pre-workout intake until they understand how Harmonize feels for them.
Who should avoid Harmonize? +
Anyone under 18, pregnant or nursing, taking hormone-related medications, or using MAO inhibitors or dopamine-related medications should avoid it unless cleared by a clinician. The formula contains DHEA, an aromatase-focused compound, and neurotransmitter-active ingredients, which makes interaction awareness important.
