I would start my HCG the last 3 weeks of my cycle up until my 5 days of PCT if one was not used throughout the cycle. here is swiftos aggressive PCT
3. Aggressive PCT (shutdown for 16-52+ weeks)
wk 1-8 Tamox 20mg/ED (40mg/ED first 7 days)
wk 1-8 Tore 60mg/ED (120mg/ED first 14 days, 100mg/ED next 7 days)
*HCG 250ius 2-3 times/wk (on cycle, every 8-10 weeks take a 2-3 week break [E2/PgR])
*HCG should also be ramped to 500ius 14-21 days from PCT
*Aromasin 10mg/EOD (on cycle)
