Look up dosing protocols, suppression profiles, half-lives, and PCT timing backed by peer-reviewed studies. Make informed decisions with actual data, not forum advice.
TL;DR
StackItSmart is a free, evidence-based harm-reduction reference for steroids, SARMs, and peptides. Four tools: Compound Database (123 compounds with cited half-lives and dosing), Cycle Builder (math-based with suppression scoring and PCT timing), PCT Generator (single-SERM protocols from actual half-lives), and Research Library (22+ PubMed citations). 21+ age-gated. No account, no ads.

Every data point on this site is traceable to a peer-reviewed publication. Dosing ranges, suppression timelines, hepatotoxicity ratings — each claim includes its source.
StackItSmart exists because reliable pharmacokinetic data for performance-enhancing compounds is scattered across academic journals and buried in clinical trial archives. This platform consolidates that research into a single, accessible reference.

StackItSmart is a free, evidence-based harm-reduction reference for anabolic steroids, SARMs, and peptides. It consolidates peer-reviewed pharmacokinetics — half-lives, dosing ranges, suppression profiles, and hepatotoxicity ratings — into one searchable database alongside a math-based cycle planner. Every clinical claim is cited to primary literature.
No. StackItSmart is an educational harm-reduction reference. It does not diagnose, prescribe, or recommend use of any compound. Always consult a qualified healthcare provider before acting on any information here.
123 compounds spanning anabolic steroids, SARMs, peptides, aromatase inhibitors, SERMs, HCG, and organ-support supplements. Each compound page lists dosing, half-life, suppression, hepatotoxicity, interactions, monitoring, and cited references.
All clinical values come from peer-reviewed literature — PubMed-indexed pharmacokinetic studies and clinical trials. Where community usage diverges from clinical data, the page flags it explicitly. Cycle protocols use a deterministic math engine (apparent depot half-life × 5 clearance), not AI.
Every claim is tied to primary literature: PubMed-indexed studies (PMIDs), DOIs, and peer-reviewed journals including the New England Journal of Medicine, JAMA, the Journal of Clinical Endocrinology & Metabolism, and American Urological Association guidelines. 22 unique PMIDs are cited across the site — browse the full list at the Research Library.
