SARM Cycle Calculator: Plan Your Cycle with Precision (Free Tool)
🧠Why You Need a SARM Cycle Planner (Especially in 2025)
Here’s the reality: Most people start a SARM cycle with good intentions but no real plan. They wing it with loose timelines, over/under-dosing, and no exit strategy — and end up confused, shut down, or disappointed.
That’s why we built the FitScience SARM Cycle Calculator — a simple, smart tool that gives you a complete layout of your:
-
Cycle length
-
Dosage timing
-
Suppression risk level
-
PCT start date
-
Suggested support compounds
You plug in your SARM, goal, and dosing — it handles the rest.
📊 What This Calculator Helps You Avoid
-
Guesswork on cycle duration
-
Overlapping compounds or dosing errors
-
Starting PCT too late (or too early)
-
Unnecessary side effects from poor planning
-
Incomplete recovery between cycles
🔧 How It Works
-
Choose your SARM(s):
Select one or stack up to three compounds (e.g., RAD-140, MK-677, YK-11) -
Input your dose and cycle length:
We’ll handle suppression estimates and active life modeling based on known half-lives -
Set your goal:
Bulking, cutting, recomp, injury recovery, or bridging -
Get a full protocol printout:
Cycle days, dosing times, support compound options, and PCT start date
💥 Example Output
Let’s say you’re planning an 8-week recomp cycle:
-
RAD-140 @ 10 mg/day
-
MK-2866 @ 25 mg/day
-
Cardarine @ 10 mg/day
Your custom cycle sheet includes:
-
Daily dosing schedule
-
When suppression begins (est. Week 3–4)
-
Suggested PCT start (3 days post-cycle)
-
Optional: NAC + omega-3s during cycle
-
PCT: Clomid 25 mg x 3 weeks or natural booster if bloods are solid
🧠Who This Is For
-
First-time SARM users who want structure
-
Intermediate users building stacks
-
Coaches building cycles for clients
-
Anyone prepping for a lean bulk or cut
-
Lifters running cycles every 3–6 months and tracking recovery
