Blackstone Labs SST-1 Kit is a dual-formula stack featuring two synergistic supplements: SST-1: GH and SST-1: IGF. This combination is formulated to potentially support goals related to training performance, recovery, and overall physical development. Each component is designed to complement the other as part of a structured supplement cycle.

Who Is It For?


This kit is intended for advanced adult users who are familiar with supplement cycles and are looking to explore complex stacks that may support their overall wellness, workout routine, or recovery practices.

What’s Inside the Kit?


SST-1: GH (Growth Hormone Support Complex)


Serving size: 3 tablets per day (45 servings per bottle)Key ingredients per serving:


  • Mucuna Pruriens Extract (std. to 500mg L-Dopa)


    This botanical extract contains L-Dopa, a precursor to dopamine, which may play a role in supporting neurotransmitter function and may be associated with natural hormone balance.


  • Anterior Pituitary Peptides (450mg)


    A blend of biologically active peptides that may mimic certain elements of pituitary output. These peptides are included to support the overall design of the GH-support matrix.


SST-1: IGF (Peptide & Nutrient Matrix)


Serving size: 4 tablets per day (45 servings per bottle)Key elements per serving:


  • NXP-GF™ (Whey Protein Isolate-derived Peptides)


    A proprietary whey protein extract standardized to contain approximately 22.25µg of naturally occurring IGF-1 per serving.


  • Phosphatidylcholine & HPBCD Complex


    This delivery system is designed to improve the transport and stability of the peptides. Liposomal encapsulation and cyclodextrin complexing may help protect ingredients through digestion and could potentially improve bioavailability.


How to Use



  • SST-1: GH – Take 3 tablets before bed on an empty stomach. This timing may align with your body’s natural rhythms for optimal effectiveness.

  • SST-1: IGF – Take 4 tablets in the morning or pre-workout, preferably on an empty stomach. This usage pattern may help support your training or recovery schedule.


Each component should be taken consistently for best results. A typical cycle duration is 6 to 8 weeks, though individual use may vary based on personal needs and supplement goals.
As always, users should evaluate their own health status and consult with a healthcare professional before starting any new supplement regimen.

Important Notes



  • Not intended for use by individuals under the age of 18.

  • Do not exceed the recommended daily dose.

  • Store in a cool, dry place.

  • Consult your doctor if you are taking medication or have any medical condition.
