Starter Growth Kit II

LGD-4033 SAFETY DATA SHEET
MK-677 SAFETY DATA SHEET

The Starter Growth Kit II is an entry-level two-compound combination designed for preclinical investigation of high-volume anabolic signalling. It pairs one of the most rigorously characterised SARMs with a long-acting growth hormone secretagogue, providing a research framework focused on lean mass augmentation through convergent androgenic and somatotropic mechanisms.

The mechanistic rationale centres on LGD-4033’s high binding affinity at skeletal muscle and bone androgen receptors, complemented by MK-677’s sustained elevation of GH and IGF-1. This combination supports research models examining the additive effects of strong AR agonism and persistent IGF-1 signalling on tissue mass accrual, particularly in studies emphasising volumetric anabolic outcomes.

Included in this kit:

• 1 × LGD-4033 | 100 pellets, 10 mg active compound per pellet
• 1 × MK-677 | 100 pellets, 10 mg active compound per pellet

Total: 200 pellets / 2,000 mg active compound.

Compound roles in this bundle:

LGD-4033 (Ligandrol) – non-steroidal SARM providing the primary anabolic axis of the kit, characterised by dose-dependent increases in lean body mass and high tissue selectivity in preclinical and early-phase clinical models.

MK-677 (Ibutamoren) – ghrelin receptor agonist supplying the somatotropic component, sustaining elevated GH and IGF-1 levels through stimulation of natural pulsatile release.

Combined research applications:

• Preclinical models of lean mass augmentation under parallel AR and GH/IGF-1 stimulation
• Investigation of bone mineral density and microarchitectural integrity in age-related sarcopenia models
• Comparative analysis of AR agonist potency in the presence of elevated IGF-1
• Research into nitrogen retention and protein turnover under dual-pathway anabolic conditions
• Studies of recovery and tissue repair following controlled catabolic challenge

This kit is positioned as an introductory mass-focused combination with predictable pharmacokinetics and a well-documented safety profile across both compounds.
