Summer Bulk Protocol

Sustanon 300 / Nandrolone Bulk Phase (8 wks) → Sustanon TRT

Sustanon 300 Protocol

Sustanon 300: Higher concentration blend (300mg/mL vs standard 250mg/mL) allowing for smaller injection volumes while maintaining effective dosing.

E3.5D Schedule: Every 3.5 days (twice weekly) provides stable hormone levels with the mixed ester blend. No daily injections required.

Nandrolone Addition: Deca provides additional anabolic effects for muscle building during bulk phase. Not reflected in testosterone chart but shown in individual compound release.

Protocol Overview

This protocol is simulated over 168 days, with a phase change at day 56.

Phase 1 (Days 0-56)

Sustanon 250 (Blend): 150mg oil (inj. e3.5d) → 113.0mg active
Nandrolone Decanoate (Deca): 75mg oil (inj. e3.5d) → 48.0mg active
Approx. Total Weekly Pure Testosterone (from T-esters): 226 mg

Phase 2 (Day 57 onwards)

Sustanon 250 (Blend): 50mg oil (inj. e3.5d) → 37.7mg active
Approx. Total Weekly Pure Testosterone (from T-esters): 75 mg

Realism Factor applied to T-Serum Chart: 50%.

Predicted Serum Testosterone Levels

Simulation of total testosterone based on all testosterone-type esters in the protocol.

Interpreting the Graph:

Phase 1 (Bulk, Weeks 1-8): With the 50% realism factor, expect peaks around 600 ng/dL and troughs around 450 ng/dL from Sustanon.

Phase 2 (TRT, Week 9+): With the realism factor, expect peaks around 325 ng/dL and troughs around 250 ng/dL.

These levels reflect testosterone only from Sustanon. Nandrolone provides additional anabolic effects not measured in testosterone labs.

Simulation Note (Testosterone Chart)

Chart simulation uses the half-life of: Sustanon 250 (Blend) (8.0 days) for overall decay rate in serum conversion. Realism Factor: 50%.

Individual Compound Release Profiles

Estimated amount of each active compound in the body over 30 days. This chart does NOT apply the realism factor.

Injection Schedule & Dosing Volumes

Compound	Interval	Phase 1 Dose (Oil)	Phase 1 Volume	Phase 2 Dose (Oil)	Phase 2 Volume
Sustanon 250 (Blend)	E3.5D	150 mg	0.50 mL	50 mg	0.17 mL
Nandrolone Decanoate (Deca)	E3.5D	75 mg	0.30 mL	0 mg	0.00 mL

Vial concentrations used for volume calculation: Sustanon 250 (Blend) (300mg/mL), Nandrolone Decanoate (Deca) (250mg/mL).

Protocol Strategy

Phase 1 - Summer Bulk (Weeks 1-8):

Sustanon 300: 150mg oil E3.5D (300mg oil/week)
Nandrolone Decanoate: 75mg oil E3.5D (150mg oil/week)
Simple twice-weekly injection schedule
Optimal for muscle growth during active summer months

Phase 2 - TRT Maintenance (Week 9+):

Sustanon 300: 50mg oil E3.5D (100mg oil/week)
Drop Nandrolone completely
Return to therapeutic testosterone levels
Maintain gains while normalizing hormone profile

Compound Breakdown

Sustanon 300:

Higher concentration testosterone blend containing multiple esters for sustained release. The 300mg/mL concentration allows for smaller injection volumes compared to standard Sustanon 250.

Nandrolone Decanoate (Deca):

Long-acting 19-nor steroid with excellent anabolic properties. Known for joint support, muscle building, and enhanced recovery. Perfect complement to testosterone for bulking phases.

Weekly Dosing Summary

Phase 1 Weekly Totals:

Sustanon 300: 300mg oil/week → ~226mg active testosterone
Nandrolone Decanoate: 150mg oil/week → ~96mg active nandrolone
Total injection volume: 1.0mL twice weekly (0.5mL Sust + 0.3mL Deca)

Phase 2 Weekly Totals:

Sustanon 300: 100mg oil/week → ~75mg active testosterone
Total injection volume: 0.33mL twice weekly
