Blackstone Labs | BSL SuperStrol-7 | 60 Tablets

Blackstone Labs SuperStrol-7 is a fully disclosed hormone-support formula built around three actives that sit squarely in the more aggressive end of the category: 7-Hydroxy DHEA at 25mg, Epiandrosterone at 100mg, and (25R)-5alpha-spirostan-2alpha, 3beta, 5alpha-triol-6-OH at 50mg. This is not a broad-spectrum testosterone booster with zinc, fenugreek, and ashwagandha. It is a tighter, more targeted stack designed to emphasize androgenic support, body-composition positioning, and a harder, drier training-oriented feel rather than generalized wellness.

Epiandrosterone is the centerpiece. At 100mg, it lands at the very bottom of the commonly cited 100-400mg range used in this category, which means the dose is relevant but conservative rather than aggressive. Biochemically, epiandrosterone is a naturally occurring DHEA metabolite and a precursor to dihydrotestosterone, or DHT, while bypassing the testosterone pathway. That matters because DHT-oriented support is often associated by users with a drier, harder physique look and a more “on” training feel. The research base in humans is limited, and there are no robust large-scale trials proving muscle gain outcomes at this dose, but its metabolic conversion pathway is well established. Subjectively, this is the ingredient most likely to define the formula’s identity.

7-Hydroxy DHEA at 25mg is included as a supporting hormonal and metabolic component. In the broader supplement world, 7-oxygenated DHEA metabolites are typically discussed for their non-androgenic DHEA-related activity rather than direct anabolic effects. Here, it likely functions as a complementary support ingredient to shape the formula beyond a single-pathway approach. At 25mg, this is a meaningful label dose, though human performance data specifically in this exact context remains limited.

The third active, (25R)-5alpha-spirostan-2alpha, 3beta, 5alpha-triol-6-OH at 50mg, is the formula’s most unusual component. This spirostan-derived compound is often marketed in anabolic support formulas for physique and performance positioning, but the clinical literature is far thinner than what we have for mainstream ergogenics like creatine or citrulline. In practical terms, it broadens the product from being a simple epiandrosterone tablet into a multi-angle hormonal support complex.

The synergy here is straightforward: epiandrosterone provides the strongest androgen-pathway identity, 7-Hydroxy DHEA adds a separate DHEA-derived support layer, and the spirostan triol compound rounds out the formula with an additional anabolic-support angle. Blackstone also appears to have considered delivery. Hydroxypropyl-beta-cyclodextrin and phosphatidylcholine in the inactive matrix are notable because cyclodextrin systems are commonly used to improve handling of lipophilic compounds, and phosphatidylcholine can support emulsification and dispersion.

From a transparency standpoint, SuperStrol-7 gets real credit. There is no proprietary blend, no hidden milligrams, and no inflated label theater. In a category where vague naming and obscured dosing are common, seeing all three actives disclosed is a genuine advantage.

What should you expect? Day 1 is not like taking a stimulant pre-workout—you should not expect an acute rush. The experience is more subtle: training drive, physique look, and overall sense of hormonal “support” are the markers users usually watch. Over 2-4 weeks of consistent use, the intended experience is a harder, drier appearance and more noticeable training confidence, with epiandrosterone at 100mg being the formula’s most meaningful dose anchor. The key caveat is honesty: this is a specialized formula with limited human outcome research, so it appeals most to experienced users who value disclosed dosing and understand the category’s evidence limitations.
