I’ve been using strategic deconditioning, and have gained an inch in 10 months this way. It’s clear proof to me that the penis needs time to recover, and two weeks is not necessarily enough. I do two-three months on, with a slowly progressing routine until I reach a decided point of over-training, then I take one or two months of to recover and allow growth to start. My last cycle brought me a 0.7 cm gain, and pushed me over the first inch.
It’s weird but I have rarely seen any gains while actually doing a routine, only during the decon, and I was lucky to stumble onto this insight about my own growth pattern through my own laziness.
I’ve been reading allot about strategic deconitioning, IPR etc. lately, and this cycle phenomena just seems to be the way I grow, maybe this could help you? Anyway, don’t be afraid to take time of, maybe your gains are just waiting to have some time to kick in.
