You said you were previously ~155 lbs and now you’re 170 lbs, so that’s a +15 lb total increase.
To estimate how much of that is muscle vs fat vs water, we’ll use what’s known about natural hypertrophy rates and creatine/water shifts.


Step 1. Key Context

Since:

You’re trained, not a beginner

You’ve been lifting regularly

You use carb/calorie cycling and probably creatine (given your past messages)


We can assume:

You’re not gaining pure fat, but not pure muscle either

A lot of the first few pounds are water and glycogen increases


Step 2. Typical Gain Breakdown for Natural Lifters

1. Muscle Gain Rate (trained lifter)

About 0.25–0.5 lb/week of muscle is realistic in a productive phase.

Over, say, 8–12 weeks (a few months), that’s 3–6 lbs of muscle max.


2. Water + Glycogen

Each 1g of glycogen stored holds ~3g of water.

A fully loaded muscular system can hold 5–8 lbs more water weight when carbs and creatine are topped up compared to a depleted state.


3. Fat Gain

The remainder of any total increase beyond that 8–10 lbs (muscle + water) is typically body fat.
Step 3. Estimate Breakdown of Your +15 lbs

Component Estimated Amount Explanation

Muscle ~4–6 lbs Reasonable growth from consistent training and adequate calories.
Water/Glycogen ~4–6 lbs Especially if you’ve increased carbs or creatine.
Fat ~3–6 lbs Surplus inevitably adds some fat unless you’ve been extremely lean-bulking.


Total: ≈ 15 lbs gain = 5 muscle + 5 water + 5 fat (±2 lbs each side)

Step 4. How to Tell Which Dominates

You likely gained mostly lean mass if:

Veins and shoulder/arm definition are still visible

Strength in compound lifts jumped up (e.g., +10–20 lbs in bench/squat/press)

You don’t look significantly softer in the waist


You likely gained more fat if:

Abs are blurry and waistline expanded >1.5 inches

Lifts only marginally improved despite more scale weight
